[PROB] TouchPro GPS lag problems

[omega01]

A lot of people have problems with the TouchPro GPS especially for pedestrian use...

From stock the TP GPS is quite unsable in car especially with TomTom 7 and totally unusable for pedestrian use.

After 2 weeks of reading and testing tweaks, here are the results of my tests and the applied tweaks to enhance the GPS performance

A. With Advanced config 3.2 http://www.touchxperience.com/fr/outil-de-configuration-avancee/telechargements/40-advanced-configuration-tool-downloads/9-advanced-configuration-tool-32-cab.html

1. disable A-GPS
2. disable GPS logging
3. logfile name must be empty
4. old logfile name must be empty
5. maximum size of logfile must be 0
6 delete the files : \windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt

7. it seems that if TomTom is installed on a fast microSD decrease the lag(have to test to be sure)

With those changes car usage will be quite perfect

B. Then edit registry with TotalCommander http://ghisler.fileburst.com/ce/tcmdpocketarm.cab

Under: HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\

- Drivers\GpsOneDevice\PollInterval -> 100 (default is 1000)
- Drivers\InputBufferSize -> 512 (default is 4096)
- Drivers\OutputBufferSize -> 512 (default is 4096)
- Drivers\SleepOnNoData -> 100 (default is 1000)
- Multiplexer\MaxBufferSize -> 512 (by default not present, you have to create it)

Tests to be done with buffers at 256...seems to be a little better
Tests to be done with other PollInterval value...seems to "drain" battery

With those tweaks pedestrian usage will be much better but not perfect...I explain.

You have to walk for a least 250m in order to have a reposition with mouvement on the map (before that, speed is always 0km/h) and then if you continue to walk there is quite no lag...and the speed reflect reality

...BUT if you stops you have to walk again for a least 250m in order to have a reposition with mouvement on the map and then if you continue to walk there is quite no lag...

Very strange indeed...

I hope this will help people...please test and feedback.

PS : tests were done with
TomTom_Navigator_7.450.9028_R3_VGA_black_edition
GoogleMaps 2.2.0.16 -- http://www.google.be/gmm/GoogleMaps.CAB
GPSTuner 5.4 -- http://www.gpstuner.com/download/GPSTuner_v5.CAB

I noticed GPS problems yesterday with Route66. Havent have time to test GPS lot before, just checked that it can find satellites and really works with Route66.

First while driving, Route66 got fix to satellite pretty quickly, but drop it then after couple seconds. Then couple secods of lag, again found satellites, couple seconds ok, drops again. This keeps going over no matter what, moving or staying stopped.

I then did soft-reset, no help. Then tried Google Maps with GPS, that worked no prob. After using Google Maps I returned to Route66 and strangely satellite fix was ok...

This might be just random satellite fix problem, but strange enough :confused:

Many of us have/had that issue so I can confirm you Its a device issue, not a satellite situation. The registry tweaks minimize that problem but I hope HTC solves the problem in his next driver/radio rom/... and the users hasnt to tweak their devices (95% of the users probably will never read this forum and they dont know how to "tweak" their devices

[freco]

Thanks for sharing. I 'll check it.

[Jorlin]

Thank you! :D

[Flippy_TK]

I applied all the patches, my TP still doesn't want to find the sattelites...

[TomasNM]

F.....g hell!!! I tried anything,and morning I've got a fix with 5 satellites in 20secs,so it looks nice(yesterday evening I did the tweaks). But after 4 hours it can see 1-2 satellites,sometimes 3,very rarely 4 under blue sky. So 2 hours of my travelling from city-to-city I didn't get a fix! Co do pici s tym je!!??(sorry for slovak lng,but I cannot speak it english,because so wrong words english language doesn't have). I bought an useless technology and HTC is rolling on the floor laughing,how the customer is stupid. F..k them all with their technologies. Another thing is wifi...no comment is better. I will maybe buy an crazy Eten with Sirf3 and HTC with their stupid Qualcomm can go to hell. For what are all the technologies here,when they are working <20% of time? I am so angry on HTC,so when my kind of device will appear,I will immediately sell the Raph.

[Kevlar-Source]

I applied all the patches, my TP still doesn't want to find the sattelites...

Same here... Don't know what else to do...
I believe I will never be able to use the GPS...
Ain't that a shame :(

But I don't get it, it used to work the first days...

For those how have still problems

1. Hard reset
2. Applied the tweaks
3. Download last QuickGPS
4. Install TomTom
5. Have a little more patience...:)

Gook luck.

Did all that and the bloody phone is still not getting a fix on satellites...

[TomasNM]

I am confused in other way...
Why it does lock the satellites in 30seconds and it sees 8 sats.and few hours after it has problem with seeing 3 of them at the same place with same weather conditions? I believe,that tomorrow(when I will not needed to have the fix,anyway I will try it) will fix the satellites ASAP. Do the Raphael have a status-sensor,that knows,if I need it right now or not? That's my opinion,while it doesn't work,when I need it and works when I testing it...
I will s..t on whole GPS technology and I will trust the plain maps as before(unfortunately,that costs me some money/energy that I spend for that).

[bbonga]

This is just amazing. Thank you!
Now I get a fix in 10-15 seconds. Earlier it took several minutes... totally amazing...:D

tried this also and been driving around for almost an hour without results is that enough patience? ;)

[lepermessiah]

hmm, my gps was working normally, applied these patches and nothing changed..still working normally (no lags etc.)

[clandestino_usr]

Applied all the patches except one (I kept A-GPS on), and after testing with iGo it's working like a charm. With the latest QuickGPS data downloaded, it can still take - seconds to get a fix, but the positioning is accurate (no more 100-200m lag), the devices sees 4-6 satellites in the Belgian sky, and the navigation is finally usable on the Touch Pro. I'll make regular checks in the coming days and I'll report the results. Thanks for the tweaks!

[Oehoe]

With A-GPS enabled the GPS works great. I had it in my pocket with GPS tuner running while running in a forrest and he didn't lose my position and no lag. The problem: with A-GPS enabled TT7 loses the fix every second. Like 1 sec there is a fix, next there is not. And it keeps doing that. When I disable A-GPS it takes way longer to get a fix with TT7 but it holds the fix.

Tip: driving around makes it harder for the gps to get a fix.

[mhsnalbarwani]

hi, i recently bought htc touch pro & i am facing problem to download gps on my phone could someone help me regarding this matter step by step.

thankx

[bauerpavel]

Well, don't forget that the sattelite network is not static. Neither is the Earth ;-)....just to explain why you'll never get the same number of sattelites at any given location at different times....just sayin'....

[Don_Zakaria]

did someone try this with a vario IV? i am wondering what the results are...

[BoldFace]

This tweak worked great for me.... Locks on in about a minute as opposed to 5 minutes that it used to. Have yet to test the lag, will do a drive around and report my findings.

[knight14th]

I haven't applied any patches. Even so the position is very accurate: While driving around the position is nearby exactly where I am. If I stop the car caused by a traffic light the calculated position is even better (within 2m). Driving on a tree-lined road the position is sometimes about 10m by the road.
I can't confirm, there is some lag or so. Also I get the first fix within 30 seconds.

Guys,
I've discovered that problem with my TP GPS is not BAD SIGNAL RECEPTION but general problem with GPS functionality (accessibility I thing)

I'm using Nav iGO8 for one month and I've tested it two or three times without major problems (250m lag to refresh location mentioned earlier is true) but yesterday I've installed simple, well known and reliable - GPS Test v1.04 (latest version afaik)

You know how it works on navigo, automapa, tomtom and so on ?
You dont know what is going till you have a fix (or not)

But with GPS Test it's much simple - GPST starting,initializing GPS hardware and show you GPS signal strenght asap.

What I've found?

Usually when starting, GPS Test need to have couple of minutes to FIND and INITIALIZE GPS HARDWARE ITSELF - There is message on screen "looking for GPS unit" and.....waiting waiting waiting

But sometimes GPS hardware is initialising in 10-15sec, then GPST showing satelites asap.

Situation is random - sometimes I'm waiting 2-3min to initialise, then just simple close and start GPST again and it works in 10sec
Sometimes I need to start GPST couple of times to get access to GPS hardware.

So this is definatelly problem with accessing to GPS hardware and finally reason of lag to get a fix.
GPS is connected on COM4 so maybe something else is using the same COM sometimes?

Still you suceeded to connect the GPS... I never got that far. I can't connect, whatever is the com port listened.
I'm now trying to hard reset my TP.
I have also made a thread about it :
http://forum.xda-developers.com/showthread.php?t=427156

[flashmp3]

Hope we have new radio that will solve all this problems

[bzdziagwa]

Do you have any VoIP software installed on your TP or did you use internal VoIP?
I'm asking about VoiP because there is known bug (known from other platforms) that usage of VoIP on WM is responsible for permament GPS problem (HardReset was a solution)
I don't remember if this bug present on Diamond, but maybe this is reason of your problems with GPS.
There is solution to update default VoIP drivers (attached to dedicated thread)

[Maranelloot]

I haven't been able to solve my GPS lag problems yet. Tried all tweaks mentioned here and there, but no luck. It keeps lagging 50+ meters almost constantly.

I tried:
- All tweaks mentioned so far (registry keys, disable agps, disable logging etc)
- Hard reset and only GPS software to test (Tomtom7, McGuider), no other external software, with and without tweaks.
- Custom ROM (DCS V14) with and without the tweaks..

Nothing seems to help. I'm calling HTC this week to see what they have to say about it.

mmm i have tested my GPS with same tool, and have no problems conecting with GPS driver anytime... works fine for me... i press Open button and starts receiving data inmedatly...

TomTom7 found the GPS hard about 2-3 seconds...

Cheers

[indiana99]

I am using Garmin Mobile XT. I applied all the tweaks from the first post and the initial fix after a reset is much quicker(3-5 min to less than 40 sec). The small lag that was there is now gone.

[zenkinz]

I just noted that my satellite reception is better when I connect my navigation software to GPS Intermediate driver/port, instead to a physical com 4.

Is it possible to use the Diamond drivers and settings?
I startet in cooking rom and i wonder if that is possible..

[egg]

Diamond is just as bad. I'm watching this thread, to see if YOU guys find a solution here :)

[gervasius]

NOTHING HELPS :mad:
I really don't know what to do...
My gps doesn't work, with all tweaks...
After 10 minutes fix on satelites, and
after that every minute lost connection,
bad reception... jumping over map,
wrong street (showing 200 meters wrong position)
:mad::mad:

really don't know what to do

[Jorlin]

[flippy]

Have all u guys made sure your settings are correct? In tomtom use the manual settings, think its called other cabled gps or something, and set baud rate to 9600 this helped me a lot. The answer was found her on xda but cant remeber who posted it.

[TomasNM]

I have noticed,that the GPS is working differently inside different cars! In my own car(Volvo 460) I have tested navigation WITHOUT any lag,5 satellites fixed most of the time. Skoda Octavia(bussiness car) is maybe blocking the signal(maybe metsllized windscreen) and the reception is very poor,while iGo/TomTom is confused most of the time. I just stand outside,I got 8 satellites visible,5 fixed(8/5). When I sit into the car,the satellites are lost and sees just 3/2. I will test it with other cars ASAP.
What the hell are the new cars designed for?

[Xtreme XL]

What the hell are the new cars designed for?

new cars come with internal satnav ;)

[Trolly333]

I also had gps lag, but not anymore. I use Tomtom and everything works fine now.

Earlier in this thread i posted my sollution, some registry settings needed to be done.
These settings i found on another board and posted them here with credits to the original
poster.

Finally someone else copied these settings from my post and started his own post. Maybe you have to ask him, he seems to know more (search xda for it).

My problems have gone away and im very happy with my tp now..hope you solve yours soon. Im keeping my fingers crossed for all those who still have problems :(

Hi,
after you stopped the car how many sec Tomtom need to show speed "0"
Regards

[Trolly333]

Hi Pajaa,

I normally don't look at it (as it works fine) but it seems like 1 second or so.

The problem that tt said 'go right in 10 meters' whilst i was already long past the exit has gone completely though. 99% of the time it's spot on now.

Furthermore i noticed that in the old situation (original without editing registry) when i was sitting in front of the traffic light, the screen would twist and turn, like tt was searching for a good fix. Now, after applying the registry edits, tt doesn't do that anymore.

So i'm happy. But....the reception is far worse than my old P3300 which was perfect. I believe that the hardware used now is crappy opposed to the sirfstar3 gps module in the P3300. What on earth made HTC abandon sirfstar3...no idea but it was a baaaad move.

Ok, maybe it's driver related i'm no expert. But atm to me it seems obvious it's hardware related (reception anyways).

[Maranelloot]

My TP is going back to HTC because of the GPS problems. I tried everything, the registry settings, different custom ROMs, different GPS software (Tomtom6, Tomtom7, Igo8, McGuider), but nothing seemed to help...

I hope they can find a solution for the problem...

For now I'm switching back to a Tytn2, which at least has no GPS lag...

[ronh]

I installed TomTom in internal memory (hey, the Pro has lots of memory to spend :devil:)
And that helped a lot.
Just a smal lag of 5mtrs, but that can also be the accuracy of the GPS.

[adolfotregosa]

guys try this in conjunction with the registry mods

Install portsplitter, write yourself com4, choose 4800 and add com6, press start.
Now on tomtom 7 choose the nmea option, 4800 and the new com 6 : port splitter

What i saw for the first time was ""12"" satelites on tomtom after some minutes of driving and tomtom was much more responsive. Ok still not perfect but i notice the diference.

I remember this because generally on the samsung pdas you have to use that program for tomtom to work with the internal gps (omnia , i780)

Post feedback.

Hi,

I suppose you keep the maps on card anyway, right? Which version of TT?
I have got TT7 installed in internal memory since the beginning but there still is a lag.

[dav3ywrx]

Well, you guys have done it again!!

I was really in two minds as to whether I should go for the TP after reading some of the reports here but in the end I did and signed up to Vodafone.

It arrived this weekend and one of the things I had concerns over was the GPS performance. I gave it a test with some GPS software and even after 45 mins of being outside and it seeing 13 satellites it still couldn't give me a fix, no good at all.

Settings:
COM4 - 9600.

Just before boxing it back up and sending it back I thought I'd give the suggestions outlined at the beginning of this thread a try. After this the GPS reception seemed far more 'aggressive' and got me a fix within 30 seconds with A-GPS disabled (as the SIM's not active yet and I don't have a data connection).

Tested with TomTom V6.010 and it perfect in the car too.

So, as I said, well done to you guys!.
Cheers,
D.

[cracou111]

Hi everybody,
My problem with the TP is also this +- 50 m lag but I noticed that the vocal instructions of tt7 are accurate! It says "turn right" precisely where I have to (this is just for example, I don't turning around ;-));)

So is it a problem with the video driver? I didn't have any lag with my Diamond with exactly the same configuration.

I tried all the tweaks, TT is in internal memory, removed the PI, ...

[hugo5]

Greetings to all!


So I've had my device for quite some time now, and since I have still not changed my mobile telephony provider (but will after october) I decided to have 2 handsets carried with me all the time (I am used to it anyways!) and hence not to rush things but give the TP a thorough testing. Here's, what I've observed:

First of all I have to state, that GPS reception is not bad at all. That said, I have to clarify: Without the tweaks it is quite bad. I am quite spoiled by a Garmin GPSMAP 60CSx device, which I regularly use outdoors, and I have to say that I use this as sort of reference.
I use IGO8 by the way, and don't intend to use anything else.

Before applying the tweaks the reception was jumpy to say the least when standing still, afterwards it got ok. Here I have to add, that I also changed the HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS\GPSMode from 2 to 1. This having the effect, that the GPSOne chip doesn't use the QuickGPS provided data and works autonomously. The first fix in this case takes really long to happen (around 30 Minutes) as the device has to get the Ephemeris Data from the satellites, but the following fixes are quite fast. I've read that using this configuration also sort of disables "static navigation" on GPSOne modules (although I know, that static navigation is a feature of SIRF chips and as such cannot be disabled or enabled in Qualcomm chips! :cool:).

The lag issue is something different. I don't seem to experience much difference in the lag within IGO with or without the tweaks. But I don't really know if this issue isn't simply caused by an "inaccuracy" of the map data. I am not suggesting that the maps themselves are inaccurate, but often I find my acutal position quite far away (saying 50 meters!) from the position on the road where I am actually. This of course is somehow corrected by the stick to road setting, but nevertheless gives a reason for a lag.
But why is the position inaccurate? I once had the problem with an older Garmin device, that I used an inaccurate ellipsoide setting, giving me quite annoyingly a wrong position. I wonder if this was the case with the GPSOne device, meaning that it was not set to WGS84. The problem is, that I couldn't find any reference as to where to change this setting in the first place.

My next round of testing will be to use my Garmin device and TP at one time in navigation using Garmin's mobile XT software. With this software I can use the exactly same maps as on my GPSMAP and can directly compare the lock accuracy of both devices.

I will keep you informed regarding the results!

Greetings, Hugo

[crocodile010]

I just tried the tweaks mentioned in first post and it looks like they helped a lot. thank you!

For all of you that don't have Advanced Config installed, here is a CAB with all tweaks from first post. Only changed PollInterval of GPSOneDevice to 250 (decimal) for battery consumption.. lower value, higer poll, higer consumption.

I should add that I found that Igo8 didn't suffer any lag problems on my TP even before I had made the reg changes - only TT7 did.

Hallo guys,

my experience so far:

repack tomtom 7 on storage card
map: dach on storage card
Tf3d is activated

Fixing absolutely no problem, within some seconds. I have tried all tweaks, especially posted from trolly333, but there is still the lag min. 50 meters, but the voice is accurately.

Tried the connection with my bluetooth sirf 3: no lag any more !

Have a nice day

[Maranelloot]

As my Touch Pro is being picked up today to go back to HTC (because of this lag problem), I switched to a Tytn2 (Kaiser) for the time being. Well, it's a huge difference compared to my TP. The Tytn2 is spot on, where the Touch Pro was always late...

I'll post it here when I know more...

[joeltje]

Same Lage here, being it that it is once in a while... It looks as though the GPS doesn't cope very well with the speed differences you have when driving (It is like a GPS unit on a large elastic band :rolleyes: ).

I try the CAB for the tweaks after I do a custom ROM on my device...

[Izzm]

i've got the same lag, like about 3 seconds (30-50 meters, depending on car speed) and nothing in this thread solved this problem

but i've got a solution to solve my 5-minutes-waiting-problem to get a gps-signal:
programs -> quickgps -> options -> 3x enable

(i disabled the second option and had to wait a very long time to get a gps-signal)

[Minus-1]

but i've got a solution to solve my 5-minutes-waiting-problem to get a gps-signal:

Hi, Izzm.

Where do you see this option ("3x enable"). Are you joking about this?

I only see three options in QuickGPS:

1. Remind me when data expires
2. Auto download when data expires
3. Auto download when connect to PC via ActiveSync

My TomTom takes FOREVER to get a fix (but once it does, it does track properly).

Thank-you!

[joeltje]

The tweaks did not improve my fix speed, as this was already in well under 1 minute. So no complaints there. I did notice improvement on the lag though, now the very tip of the arrow is exactly where I am...

The speech is spot on.

No complaints for me, as this is only a secondary navigationsystem, primary is Factory installed :)

sorry guy, i've got the german version and didnt know the english menu names

so, enable every menu option (especially Auto download when data expires) and try again a gps fix

here i get a gps fix in 20-30 secs with the option enabled, and more than 5 minutes when disabled

My TomTom takes FOREVER to get a fix (but once it does, it does track properly).

Thank-you!

That's what he means by 3 x enable - i.e. enable all three!

[gervasius]

but, my question is:
why other devices (not raphael) works WITHOUT quickGPS,
and Raphael must have quickGPS??

next question: wrong position, gps lag

[Minus-1]

Lol Izzm & apd!

I feel so silly now. :)

Like you, I had all of them set 'cept option 2 ("Auto download when data expires"). Of course my thinking is/was why would I set this if I'm already syncing the data much more frequently than the expiry period, etc.

But, I will set it and hope somehow that it is a magical fix!

Oh boy (pinkies crossed). I'll let you guys know!

Thx for the help.

As my Touch Pro is being picked up today to go back to HTC (because of this lag problem), I switched to a Tytn2 (Kaiser) for the time being. Well, it's a huge difference compared to my TP. The Tytn2 is spot on, where the Touch Pro was always late...Thanks for that feedback. Aside from the fact the screen cant be tilted like on the TyTN II for watching videos, the poor GPS on the Touch Pro is yet another reason why I'll be hanging onto my TyTN II (with standard WM 6.0 ROM) until something truely better comes along. Nice to know the TyTN II isn't obsolete yet :D
A shame HTC don't seem to be very good at sorting GPS (and general) driver issues though.

[mrvanx]

OK so far my replacement raphael has had some major GPS issues so ive been hunting and testing out things.

The problem was that it wasnt getting a fix AT ALL, regardless of if i was outside in an open area or indoors, i left it searching for a fix for a couple of hours to make sure and no deal, finally i spotted the (apparently) newer HTC GPS tool floating around and tried the technique posted earlier of clearing out the memory and turning off QuickGPS which did the trick.

The raphael now aquires a fix, nice and solid, in around 20 seconds when in a decent are, indoors doesnt work well at all but who cares?! :)

Ive attached the cab for reference, just clear the memory then leave it for a while to aquire a fix on its own steam, untick ALL the options in QuickGPS.

I suspect this is only an issue for certain models as later models seem to work fine. I cant comment on LAG just yet as ive done no testing of it.

Let us know when you have results regarding the GPS lag. Without QuickGPS it takes up to 5 minutes before I get a fix. With QuickGPS I get a fix in 20 seconds. I only have a few seconds lag, but if you trick can fix the lag completely, i'd happily turn on tomtom 5 minutes before I go out to drive. ;-)

tomtom7 navigating becomes sooo crappy!
lag still remains yet, and my position on the map is warping like tabletennis ball in a whirlpool :<

[TomasNM]

Your position is jumping around your current,but I tried today iGo8 and my position was in opposite direction,so the map was going backwards. Tomtom was much better in this case. But as I said before...it varies with different cars. Don't know why,but in my bussiness car Skoda Octavia is the navigation useless(of course,because in this car I am travelling most long ways and I need it sometimes in strange locations - Murphy's law). In my private car(Volvo460) and also in friend's Seat Alhambra was it working very good with more than 5 sats fixed all the time(travelling via known locations,just testing). Geocaching is also possible in the forest with very good accuracy <10m(using Beeline GPS). So why the new,expensive cars are designed for signal cutting?

For the record - i've tried this registry fix and it doesn't improve the lag at all! In fact, I've noticed other anomalies too.

Oh well, it seems that us Touch Pro owners will have to put up with GPS lag forever because I'm sure it is a hardware issue.

(Mark my words).

I haven't noticed the lag in the 3 weeks I've been using my Vario IV, it's always spot on.
(If it's hardware, then something should be different in the T-mobile version RAPH300)

[groofoo]

ok, here is a little thing i found while using tom tom.

this afternoon i drove to my work using the tom tom nav app.
no lag or what so ever, like before (never had a lag problem).
until someone called me, i anser the call, the screen goes to black, ended the call, turned the screen back on, and switched back to tom tom using the taskmanager.
and there it is, a 50 meter lag.

i solved the lag by shutting down tom tom, and starting it up again.

so i was thinking, on my old (very old) SPV M500 with an external GPS reciever.
if i didnt have the phone capabilities (flight mode) on, the bleu tooth function wasn`t working, (blue tooth didn`t work).

on my trinity, if the phone was in flight mode, the internal gps reciever would not start.

so maybe if you have a poor phone connection to yourre telecom provider, you may suffer from this lag.
its just a suggestion what i tought off.
maybe it has nothing to do with each other but ... the noob as i am ;)

[topspeclt]

Thanks for that.

Could you possibly supply us with details of your ROM and Radio versions?

I highly doubt they changed the hardware between the two.

[karloe]

Details as in the Wiki for the Dutch T-mobile ROM ;)

[ice_coffee]

I used my GPS for the first time last night, im using an older version of tomtom 6 and could not notice any real issues, I have made no modifications to the registry, but I am using ROMeOS v1.12 I only got my TP on saturday, it is an 837K model

[GenghisZ]

I'm surprised reading all this negative comments, because +/- 2 weeks ago I flashed to DCS v15, and started using GPS frequently.

At first I took my TomTom One v2 with me, and used it together with my Touch Pro, to check if I could notice any lag issues.

I did not change anything that is GPS related in the register, but I keep QuickGPS up to date (also A-GPS I think, but not sure how to check that ;-) ).

Anyway, getting a sattelite fix on my TP was 5 seconds faster then on my TomTom, so no issue here (it took around 20-25 seconds).
The screen and voice are IDENTICAL, it was actually very funny to see the map and hear the voices in sync :)

The only strange thing I noticed, was that when I stop the car, my TomTom shows a speed of 0 km/h in like 2 seconds, but my TP shows 3 km/h in 2 seconds, and after another 2 seconds it goes to 0 km/h, altough the blue triangle stays put.
On the other hand: While accelerating from 0-140km/h, I did not see any speed differences between my TomTom and TP.

I have no clue on why I have no problems, but I am very pleased with my GPS @ TP. Yesterday I even tried it in Brussels (big buildings, no open sky, etc etc) and my TP had better reception then my TomTom v2!

During the 2 weeks of extensive testing (TP plugged into power, TP on battery, TP on dashboard, TP on backseat, TP in car (Ford) with QuickClear windshield!!, TP in hand while walking, etc etc) I did not encounter any lag or long fix time.

[MenosOcho]

I was reading several post and my doubts is about of tweaks of first post..
It supposed work only if you've selected the "GPS Intermediate Drive" inside of GPS software (TomTom or Garmin Mobile XT) or it work too if you use direct connection to COM4?
I use Garmin Mobile XT and i get better signal if i use COM4, but i'm experiencing the same lag..

For anyone who's considering buying the Touch Pro, perhaps their best option is to contact HTC using a choice from all the above methods of communication to get the required updates on what HTC is doing to resolve the problem. I certainly wouldn't make any purchasing moves though until after any supposed fix has been released and positively reviewed to fix the problem fully. I was told on more than one occasion by HTCs tech support, when the TyTN II video driver debarkle was at its peak and they were getting loads of complaints, that they'd provide video acceleration drivers for the device in the future but look what happened. On a premium 'flagship' product like the Touch Pro it's a disaster that GPS problems have followed on from its predecessor the TyTN II with WM 6.1 ROM.

If sales are seriously affected on this high priced/higher profit model, then maybe they'll listen and be more responsive towards fixing the issues.

I don't know about the ROM you are using, but on ROMeOS, you can choose to turn it on and off (like I said mine is off)

Start --> settings --> (choose SYSTEM tab at the bottom)--> AGPS icon top center

What I love about this, is how fast it is, coming from an athena and a universal with intel CPU's and crap video acceleration it is such a breath of fresh air to have TOMTOM start in >5seconds and also when it is re-routing it is SOOOOOOO fast compared to me previous devices, I always assumed that the TOMTOM peeps deliberately caused the poor performance on WM devices so the could justify their standalone units, but im using the same old version of S/ware and it works perfectly, I guess it was just crappy WM devices.

Just wondering: is there anybody who has their Touch Pro sent in for repair for this problem? The lag is really making me so sick, and I'm willing to lose the phone for a couple of weeks if it would help...

[topspeclt]

I used TT7 (7.451 Sep update) without QuickGPS (out-of-date). Here's what I noticed:

The time to fix before was around 10 secs now it's around 2-3 mins (because of the out-of-date QuickGPS I suppose).

I travelled around 6 miles in and around town and guess what? No lag. The position was spot on throughout the journey.

I didn't try IGo8 because I didn't have the guts to disturb my 'joy'.

I'll report back if the situation changes but it looks like my problem with TT car nav may be solved.

When i first used Google Maps on the Touch Pro it got my location right to the exact parking space. Next day I needed to drive somewhere by a back route and it wouldn't connect at all.

This morning I had nine satellites. This afternoon couldn't get a lock. This evening it is working perfectly.

Really frustrating.

I have not seen a difference in GPS lag with or without outdated QuickGPS. Only that the fix is a lot slower when QuickGPS is outdated. Luckily my GPS lag is not unusuable, it's just annoying.

I wonder if they test their products before sell them. And even worst, they know the poor performance but dont worry about it....:confused:

When working I get a few meters lag, but nothing compared to Tom Tom 6 running with an external GPS on my old Treo.

May try charging the external GPS box and using that for driving instead of the internal GPS.

Hello,


Like i said you in my last post i make a lot of call to HTC SUPPORT.

Today i receive an email from HTC SUPPORT :

"Good Afternoon,

Thank you for contacting HTC Europe.
HTC are aware of the issue you have described in your E-mail and we have escalated the issue to our technicians, we hope this will be resolved shortly. Please send in any other information that you think might be relevant such as which GPS Navigation Program you are using and which third party software programs you yourself might have installed. Send these in with the above Reference number in the subject field. Thank you very much for your input."


So may be HTC make an Hotfix.

So il you encoured the same probleme of your HTC Diamond GPS please send an email to HTC SUPPORT !!!!

Here my email so support :

"Inquiry Type:Technical Support

I tried it and much lag....

[cribeiro]

I have Eten M800 with a very good Sirf Star III GPS receiver. Also I have a Sirf Star III external GPS receiver Holux 236, also a very good GPS receiver.

I put my Touch Pro (TP) and my Eten M800, both with Tomtom 7, side by side, running in the car, driving about 60Km/h. I observed that Touch Pro has a lag of 0.5 to 1sec in time in the voice instructions and 10 to 20m of distance in the map.

Next I put Touch Pro receiving the GPS signal from Holux 236 using bluetooth, not using internal GPSOne receiver.
Again I put Touch Pro and M800 running TT7 side by side. Now, Touch Pro has no lag; the information (voice instructions and map information) coming from both PDAs are exactly in synchronism.

So the lag problem in TP is coming from GPSOne internal receiver, not from any ROM or from Windows mobile or from tweaks.

Next I put my Tytn II and M800 running TT7 at same time. I begin walking. M800 takes 3m to show my speed (about 6Km/h) and Tytn II takes 20 to 30m to show my speed. I get the same result making this test with TP and M800.
As Tytn II is a GPSOne, this test seems to confirm that the problem is coming from GPSOne technology.

[RavenY2K3]

Just thought i'd let people know about my little experiment today.

I got both my Kaiser and Raph side-by-side whilest driving around today and there was hardly anything in it, in terms of which performed better, i have applied the different settings mentioned in this thread but my initial problem wasnt with lag as such, yes it did do it occasionally but nothing i couldnt live with.

The main problem i had/have is it over heating, which i have now worked around by possitioning my car holder, in such a way that cold air blows on the Touch Pro from the air vent and even more so when the AC is on.

But i can concluded from my tests (117 miles throught out the day) that at least for me, its no better nor any worse than my Kaiser is. I found the signal strength to be stronger on the TP than my Kaiser, and when TomTom issued its order, both device's gave the commands at almost the exact same time (im using TT 7.451).

So from what im used to with my Kaiser im happy with how these settings have worked for me, because although i only got s slight lag, its none existant now, who know's perhaps the fact ive got cold air blowing on my device is helping some what as it no longer gets hot, slightly warm, but not hot.

:D

[Don_Zakaria]

[DeepThought]

Today I did a similar test like cribeiro:

I used my stand-alone-satnav and my Touch Pro at the same time. Both devices have the exact same version of iGo8 installed.

At 80 km/h there was a difference of about 1 second. So if my math isn't to bad that means a difference of about 22 meters in position. At about half the speed the deviced almost matched in their voice-commands but not always. In areas with bad sight to the sky (high buildings on both sides) the gap between both devices was again one second but at a speed of only 30 km/h.

[Upquark]

My tests indicate a lag of about 2-3 seconds, which is about 40 meters when driving in town. That is just way too slow for comfortable navigation.

[Maranelloot]

Maybe a lot of people didn't notice the GPS problems. But if you compare it, then you will see the difference. I used the gps from my trinity and compare to the raphael it is far superior............actually the gps is useless on the road.

A good friend of mine has a Vario IV (technically identical to the TP) and when compared, his is spot on where my TP lags about 50 meters. Tomtom versions, maps etc are all identical...

Can you ask your friend to dump the ROM and post here to take a look at GPSOne driver?

[Maranelloot]

Mine is a Touch Pro T7272 WWE, one from the first batch (got it the day after it came out). In other topics/forums it is suggested that mainly the first batch has problems with GPS, which makes me think it's a production fault of some kind. But it's not confirmed anywhere, so just guessing.

[onderduiker]

If it's a hardware problem, then they should fix it. A "pro" device deserves a better GPS system........and it was a lot money we spend on this device.
Still hope there is a solution on the way.

Sorry, but for me the lag is not acceptable because the gps is technical not good.

If it's a hardware problem, then they should fix it. A "pro" device deserves a better GPS system........and it was a lot money we spend on this device.
Still hope there is a solution on the way.

@jcespi2005
Sorry, but for me the lag is not acceptable because the gps is technical not good.

You mean 5-10 meters is not acceptable? GPS signal have 3-5 meters error margin... so 5-10 meters lag can be a normal function of every GPS unit... but i can be wrong, only thinking...

Used my GPS in anger for the first time last night from Calais to Amsterdam.

Stock Touch Pro with CoPilot Live v.7 for Touch Diamond.

There was some lag maybe as a previous poster has said of 5 - 10 meters, but it got me back here, I didn't miss a turn and everything worked well.

I noticed more lag when trying to walk to somewhere using it - CoPilot kept freezing and was barely usable, but for driving - certainly on last nights experience, it seems acceptable to me.

[Maranelloot]

5-10 meters is acceptable. 50+ meters is not... The difference between my device and the one from my friend is quite big.

[rotohammer]

I've used my Kaiser with TT6 & Igo8 for the last year, so I know what to expect.

I'm away and used my Touch Pro yesterday to get somewhere 40 miles away, mostly highway. Through the whole trip, Igo8 would go crazy, the display looked like I had shifted miles off course and the map would spin in circles. Then Id get a lock (im guessing) and id be right on track. Its very discerning when your trying to watch for the next turn and the nav system freaks out.

And then theres the lag, I drive fast (80-85mph) and the lag gets worse the faster you drive. That I can deal with it, but its dissapointing considering my Kaiser worked so darned well.

Ill test the fixed posted here and report back.

[onderduiker]

exactly......compared to another device from htc (mine trinity) the gps is no good
The strange thing I noticed that the voice of the navigation program didn't have a lag or something. It seems the instructions are on time :confused:
......or am I wrong ?

I notice with TomTom7 the zoom in navigation screen sometimes makes the redraw a bit slow, so i disable the autozoom function, and choose a high zoom level, perhaps this helps with tomtom7...

The redraw on my trinity was always very quick. The raphael is technical faster, so why is the redraw a lot slower ? (VGA screen perhaps ?)

But,
Just given my raph a hard reset and start al over. (How many times did you hardresetted or change the image from your device :D:D)
............spend already a lot of time on this thing I believe :p

Of course VGA screen don't help in this case, but resolution is resolution... i love VGA but i'd love more TomTom makes a version that use of D3D in TP to take advantake not only of processor speed, but also of graphics accelerator...

how many times i flash my device? jejejeje too many mate, i coocked a lite spanish version and tested many times jejeje flash is very adicctive :D

[Gigs]

Guys,
As I have tried all the fixes for GPS in this forum and still my position lock is slow and the lag is still present (about 1 second or shall we say 40 meters?) I have made a video of what happens after 5 minutes of trying to lock position from my balcony at the second floor of a block.
In the same position, in one minute my eten m700 with sirfstar acquired fix...
If you look at the video you can see the strangest of all: the satellite position is not fixed! They jump around 1 mm at 2 seconds interval.
Maybe someone has an idea where can I send this video (press, HTC support) so that it can be of use?
I mention that I allready sent three support requests using htc webpage and technical support section, but I received no answer from them.
Device SN is HT832K and my location is Romania.
You can download the video from
http://www.drivehq.com/file/df.aspx/publish/gigs2/PublicFolder/mov00955.avi
(Uploading a zip file of 5,2 MB using the attachments seems to have put the server in an "hate" position towards me)

[Nghiem]

I think there are some problems between WM 6.1 and Qualcomm chipset.

I'm on tilt (kaiser) and I don't have a Touch PRO, yet. Prior to WM6.1, GPS got fix well under 55 seconds; meanwhile GlobalSAT BT 559 w/ SIRF3 Bluetooth GPS receiver chipset gets fix in less than 40 seconds (cold fix.) Now with WM6.1, I feel I'm lucky if tilt gets GPS fix less in than 150 seconds. However, my friend's Artemis (SIRF3) goes fine with WM6.1

[ferus]

I found out the following (if it is already known then I apologize but I don't have time to read the whole thread):

Today, I was travelling with a friend who has a MIO PDA with TT7 installed. The 50m lag was definitely seen on my Touch Pro however the voice navigation was without any lags. Both GPS devices were talking at the very same time - only the video display of TP was lagging behind.

Can this be a graphics/driver problem?

[topspeclt]

yeah it does..I believe by ATI

Are you sure because I thought it was the Sony X1 with the ATI graphics accel.

Do you have a link or reference to support this?

It would make my day! :)

[utvol06]

HTC made the guts in the X1..the internals are the same as far as I know with the Touch Pro and X1. There would be no TouchFlo3D without video acceleration I can tell you this much. Whether both use the ATI chipset for video acceleration I don't know, but they both have hardware video acceleration. Neither the Xpanels nor TouchFlo3D can work with out it.

[NetRipper]

There's no ATI chip. The MSM7201A chip does have 3D acceleration though, but not as good as the ATI chip that the Hermes, and possibly other devices, had. Coming from the Hermes it's quite annoying to see that the Raphael and Diamond are performing so badly graphically in Tomtom. I'm not sure if TomTom is making use of the graphical capabilities, so I hope there's space for improvement.

[onderduiker]

Like I said, I started over again.
My installed rom was DCS-TouchPro-v15 because navigon "worked" on that rom.

Lets do something different........installed ROMeOS v1.13. Before I tried 1.12 but that didn't work with navigon because it find no gps. I thought give 1.13 a try, maybe it will do it with navigon. But same thing........no luck with navigon.
Changed the radio rom to 1.02.25.28 .........but still no luck with navigon.
I like this rom, because it is fast and stable. Installed tomtom instead of navigon. And wow...........it works like a charm. Can't notice any lag at all.
So finally I think......navigon was "my" problem.
I like navigon more, but for me it is not working on my raphael. Maybe the new version 7 is working. But I have to be sure before I buy the upgrade.

[eu_beu]

Hi,
I am new on this forum. I have a TP with iGo8 installed.
I can confirm that the lag is due to the TP, not to the software. I have on a P350 installed exactly the same iGo8 and it is working very well, no lag at all.
I put both on my car and the differences are more than few seconds. On TP is like a "lazy" hardware. When I am start moving the car, the P350 is showing immediately the changes, but the TP is "waking" 5 seconds later. The same when I am stopping - even I am still already, TP is showing like I am still on the move for 5 secs. This is not so problematic, but it is very annoying when you miss a change of direction, due to this delay....:mad:
I tested what you posted from the start, changing the registers ... nothing to do. Maybe it is working on TT, but on iGo8 is not working at all.

[GroinsNZ]

I've been having the GPS lag problems with my device as well.

I've done all of the registry tweaks I think but no improvement with the lag issue.

Lately, I've been testing the GPS with iGO8 and at first I had the Baud Rate set at 57600 on COM 4 but I noticed that the Satellite signal would come on intermittently and then disappear, effectively resulting in a positioning lag. Today I set the Baud Rate down to 38400 and this resolved the issue with the Satellite signal continually dropping out. I am certain (or would like to believe so) that there was no lag either, however, I only had the GPS running for a short (approx. 2Km) distance while driving home tonight so some more testing is required to confirm this.

So anyway, if you can, perhaps try your GPS with a different Baud Rate. Stock is 4800 and up from there you can possibly select (depending on the software you’re using); 9600, 19200, 38400 (could be a sweet spot for mine) and 57600 (didn’t work for me).

Cheers,

[Maranelloot]

Got my phone back from HTC and tested it together with a Vario IV (with DCS v14 custom ROM). It seems to be doing better now, it lags only marginally. Still need to do some extensive testing though. Not sure what they've done though, besides a hard reset. Serial numbers and IMEI are still the same, as is the MAC address. According to the sheet that came with the phone, 'no errors were found'...

As soon as my car holder is in, I'll be comparing it to my Tytn2, which is working perfectly.

[adonker]

Hi All...

Ive tried everything;

* Different Roms, including official T-Mobile ROM
* all the adviced shown in this forum
* HTC GPS tuner.

last week I soft resetted the TP, runned the HTC GPS tool with clear memory option. After that TOmTom worked for one time, next start up TomTom coudn't get a fix again...

Reading this forum and other GPN forums it is clear that the TP has a GPS problem.
I've called T-Mobile and they said to send the phone to them for repair. TomTom was working for once, so it must be a software problem?

So no one had got a fix for this problem? HTC and T-Mobile are selling something which isn't working richt?

Very strange!

I tried this morning decreasing the Baud Rate till 9600 and the results are the same .... the lag remains the same ....
It is very frustrating ....:mad:

[GroinsNZ]

That's a shame mate.

I had more positive results today when I used the GPS for going to work and back, a 30km ride (motorbike) each way and it worked really well. The iGO8 software, once configured properly, might be why it's working so good. The turn-by-turn voice commands gave me plenty of warning for upcoming turns and was good at letting me know I was doing over the posted speed limit too ;)

As a side, definitely a nice application, much better than Garmin XT that I was using previously.

Having fiddled about a lot with the GPS I have now managed to acheive a lock on tomtom 6 in about 6 seconds and virtually no lag. Here are the steps i have taken.

Install TOMTOM
Install GPS Test (http://www.chartcross.co.uk/products/WM00002_details.asp)
Install GPS Tweak CAB (attached)

Open Tomtom and under the GPS receiver settings, select other NMEA GPS receiver and select baud rate 9600 and com port 4.

Close Tomtom.

Make sure that before you run Tomtom on sebsequent occaions that you run GPS Test first. Under GPS settings select com port automatic and baud rate 9600. Once it says GPS running, (usually 10-15 seconds) minimise the program then start up Tomtom. Once Tomtom has a fix then close GPS Test and all should be well.

I now usually get a fix in about 6 seconds. I find if i dont run GPS check first then it can take about 20 minutes to get a fix in Tomtom.

I know this may not fix everyones but it did for me so i thought i would share. :)

Hi All,

my tp gets fixes in a short time but lag lag lag...

i had a chance to test my tp with igo8 and garminxt, but the result was same,50+ m lag, opposite way, like a labyrinth.

i read all posts about this problem and i dont think that anybody found a certain solution.
i want to ask you that, i couldnt test it with my BT-338 SiRF Star III Bluetooth GPS,
can anybody explain how to use ext. bt gps receiver on igo8 step by step?
and i cant adjust the baud rate, my default hardware port is "none" and baud rate "4800".i change both of them but when i turn back they re same.

i will be glad if anybody helps,at least i want to test with bt gps receiver to see the difference...

Thank you...

First of all...I've already tried all fixes and improvements mentioned here and in other posts - with no results - there was permament problem to get FIX.
Today I've made some general changes on my TP and observed GREAT improvement:

1. Installed 1.02.25.28 radio
2. Tried GPS Test but no results still problem to get fix
3. Did some changes in Settings->External GPS

Settings ->External GPS -> Programs TAB -> COM5,
Settings ->External GPS -> Hardware TAB -> COM4 speed 57600
click OK

hardware settings were changed back to NONE 4800 but for programs COM5 is now available.

And....for GPS Test it takes about 40sek to get FIX !
tested on Nav iGo8 - takes about 30-60sek to get FIX !

I was really surprised so did two or three soft reset to confirm that situation is stable but GPS is still available.

I will test GPS lag tomorrow and let you know.

i m waiting your good news and i m going to test my tp with igo2006+ tomorrow, i wish to get no lag.

i change them, when i exit setting and go back again its same.

i will be glad to get an answer about this prob...

It seems from extensive reading through this post - most are married to TomTom... could this be because it is freely available as Warez?

Well, following your post and recomendations i do a test changing the TomTom parameters without changing nothing in Setings/ExternalGPS and the Lag decreases a bit more, so now i have no lag, only 3-5 meters, and TomTom 7 redraw the position very quick and smooth...

Attached is my GS config inside TomTom.. nothing changed in externalGPS configuration...

[doublecheese]

Guys, I'm really thinking that there is problem with your GPS chip if you have lag. I will tell you why.

I have a friend who bought a unlocked TP from USA about 1 1/2 month.

I have bought mine while visiting USA about a month ago. .

3 weeks ago I loaded , IGO8 and GARMIN XT on my TP , and it works perfectly well, no lags no nothing, everything perfect.

At the same time I loaded the same IGO8 and Garmin XT to my friend's TP. He has alot of lags, the gps position is not correct sometimes, etc etc.

Now think like this; two HTC Touch Pro's bought at the similar times, both from USA. All radio and Radio versions are the same

One is working perfectly , one has problems. We're using the same navigation softwares and we made side by side comparision..

To solve the lags, he had hard resetted his TP atleast 4-5 times, did all the registry and other tweaks, he changed the raud rates , it all helped up to a certain point. His TP's GPS is never as good as mine.

So after these comparisions , I surely think that people with GPS lags/problems should report this issue to HTC.

Because here is a living example what I just explained.

[DeepThought]

@doublecheese

You are right, it seems that some TPs seems to have this problem and some not even if they are exactly identical regarding to software versions.

But that doesn't necessarily mean, that the bug can't be fixed with a new radio or a better GPS driver in the OS.

But that doesn't necessarily mean, that the bug can't be fixed with a new radio or a better GPS driver in the OS.

in 2006, I bought myself a FSC N560, it has a great large screen and a very fast processor. N560 had been my main Navigation source when I'm navigating due to it's large screen.

It was working like a charm, however just until recently I started getting lags and the gps sensitivity has been much much worse. I used to get full satellite bars, now I can't get even half bars and also suddenly all bars disappear. However sometimes the bars become full again.

This clearly shows that , my N560's satellite receiver is not working as it used to somehow. It had been working fine since last two years, but suddenly it behaves like this.

With my friends TP the results are similar, that's why I think the GPS receiver is faulty.....

I am also starting to think that the real problem is the "GPS driver in the OS", because, so far, no tweaking, what so ever, really works.

I've read that that TP GPS has trouble holding a signal in built-up areas - e.g. driving around London. Can anyone share their experience of regular use in a city like London?

[Black1982]

I have a Dutch Vodafone branded TP.
ROM: 1.90.172.4 nld
rom date: 23/08/08
radio: 1.02.25.19

I had problems with GPS lag about 25-50 mtrs.
I applied the XDA JCEspi2005 GPS Lag Fix Raphael and installed the Nadavi_HTC_GPS_TOOL.
After this my gps using Google Maps and TomTom 7 (pre-installed)is very precise.

Since i installed them both at the same time i'm not sure what is fixing the problem, but my guess its the JCEspi2005 tweak!

The Nadavi_HTC_GPS_TOOL seems just for testing your connection but i'm not sure about what it does exactly.
If someone has more info about this tool please share your knowledge.

QuickGPS workes perfectly for me for getting a quick fix by the way.

My guess is that most of the GPS lag issues are software/registry related.

[rockywall]

I have had my TP for over a week now and have tried the GPS tweaks on this site to no avail. I installed Franson GPSGate and it worked perfectly. I also had this problem on the Diamond and GPSGate fixed it. My wife's touch also has GPS problems with WinMo 6.1 and GPSGate fixed them. I think the problem lies in WinMo's attempt at "managing" the gps, under Settings | System | External GPS. Myabe it is not compatible with HTC's chip. However I have turned that off and still have the same problems and a few others. I will stick with Franson until HTC comes out with some sort of fix.

[TheDuck]

There's been talk on a couple forums about Sprint's delay for the TP being to fix several issues, including GPS lag. Also, the fuze is/was delayed until Nov xx because they also were waiting for a ROM update, according to one of the posters.

Does anyone here have an advance copy of the new AT&T ROM to test whether the fix really worked?

Here's a link: http://www.wmexperts.com/articles/inside_an_htc_facility_rumors.html

and here's a quote:

(Delay for Sprint Touch Pro release--why? Needs a ROM update to fix the following:

* Camera Lag issues: Software
* GPS Lag issues: Software/reg edit
* TF3D exception issues: software/reg edit/update
* Camera Update - Software
* System Performance with Processor - Software Update/patch
* Speaker Volume issue - Check Hardware - Software/AD Update
* Control PAD malfunction - Software/Update

Be seeing you,

All of you who's having GPS lags and other problems.


Just try pairing your TP with a Bluetooth GPS and see how perfectly it works out of a sudden.

My firend who was having GPS lags, says that after connecting to a bluetooth GPS rather than the built in GPS, his all GPS related problems are gone.........

This clearly shows again that there is a problem with the GPS Chip of the TP on some devices with lags .......

[Matthes42]

Thanks for your logical attempt to find the reason for the lag. Don´t you think that an external gps mouse uses another driver than the internal onboard device? So it might be a driver issue as well :D

My firend who was having GPS lags, says that after connecting to a bluetooth GPS rather than the built in GPS, his all GPS related problems are gone.........

This clearly shows again that there is a problem with the GPS Chip of the TP on some devices with lags .......

[doublecheese]

OK, how about this then ?

As I mentioned above I and my friend both have the TP, our phones are same, with same Roms and radio versions , bought from the same country within same similar time period.

But one of them works perfectly, one has problems .......

why would one work and the other don't

[ludovic.audoin]

Thanks for your logical attempt to find the reason for the lag. Don´t you think that an external gps mouse uses another driver than the internal onboard device? So it might be a driver issue as well :D

Hello, for your information, I tested TT7 with an external GPS receiver (Globalsat) and I have the same lag issue...

[speed200]

I´ve just read a small review about the HD and it does n´t have the GPS problems of Pro.
If only we could get the GPS driver to test...

[cribeiro]

I have a Touch Pro, an Eten M800 with a very good Sirf Star III GPS receiver, a Sirf Star III external GPS receiver Holux 236 (also a very good GPS receiver) and a Tytn II.

I put my Touch Pro (TP) and my Eten M800, both with Tomtom 7, side by side, running in the car, driving about 60Km/h. I observed that Touch Pro has a lag of 1sec in time in the voice instructions and 10 to 20m of distance in the map.

Next I put Touch Pro receiving the GPS signal from Holux 236 using bluetooth, not using internal GPSOne receiver.
Again I put Touch Pro and M800 running TT7 side by side. Now, Touch Pro has no lag; the information (voice instructions and map information) coming from both PDAs are exactly in synchronism.

Next I put my Tytn II and M800 running TT7 at same time. I begin walking. M800 takes 3m to show my speed (about 6Km/h) and Touch Pro and Tytn II take 20 to 30m to show my speed. I stop until TP and Tytn II show 0 Km/h; I wait stoped 2 sec and begin again walking - after 5 meters TP and Tytn II show the speed. I stop more than 30sec - I will need to walking again 30m to get the speed in TP and Tytn II.
As Tytn II is a GPSOne, this test seems to confirm that this problem is coming from GPSOne technology.

I drive at 60km/h side by side M800 and Tytn II; Tytn II is precise like M800; it has no lag.

So I guess that the lag problem in TP is coming from its GPSOne internal receiver or its driver, not from any ROM or from Windows mobile or from tweaks, as Tytn II has no lag and also is a GPSOne.

I have an HTC Touch Pro with a stock Sprint ROM. I was fed up with the GPS lag and about to return the phone.

But I tried the GPS Tweaks cab from this forum - and it fixed the lag issue 100%. If there's ever any lag now - it's going to be at most 3 meters as opposed to the 50 before I applied the cab file.

So - I recommend trying that tweaks cab before giving up.

[polkadots]

Is there a thread/tutorial on editing the registry? I'm planning on doing the GPS fix but want to know if there's anything I need to know before doing the edit.

I have taken the GPSDriver from a touch pro which don't have any fix problem, but if I overwrite mine driver my device doesn't recognize the GPS any one of the masters want to try it?

Hi guys...

I recently upgraded my Nokia for a Touch Pro, and life has been so much "laggier" and patchy with the faulty GPS and poor 3G/GSM reception.

Iv'e just sent HTC a rather long email, hoping to get a reply in a day or so, and they'd better, or else I'd be spamming them each day until I get a reply.

At the moment, for me, the only way to use TomTom 7 is via an external BT GPS device. I don't get why the time for a GPS fix is a minute at least (stationary, in car, clear view of sky), and why my location appears to be 300 metres away from where I actually am. I don't think the VGA screen has anything to do with CPU lagging etc.

Currently my TomTom GPS screen shows my coordinates, but there are no satellite data available (none in view), and on the homescreen, TomTom shows me that the GPS is working (the colours of the map are not greyed out), although my signal shows nothing.

Tried all the fixes here, but nothing seems to work at the moment, I'll probably return the Touch Pro at a 3 Shop next week, hoping to test out another one.

I don't really believe that all the Touch HD's will be lag-free. Iv'e read quite a number of reviews of the Touch Pro before I got one, and the GPS was described as 'excellent', with no faults.

what map prog are you using?

i applied the gps tweak cab and also install gps test.cab and i use igo 2006 and also beelinegps. both still sucks after all that ... ;(

what comm port speed are you using?

when you mean problem fixed, is it totally fixed?

btw, i am using a sprint tp also.. thnx

[Sander]

With my Touch Pro it helps to select another gps device within TomTom, after that I set it back to internal gps and it almost instantly goes searching for satellites. Hope this helps someone.

[laft2k]

I found the only way to eliminate the lag and fix time in tomtom was to have gps test set to com port auto. If it was on com 4 then it would lag about 10 meters.

[doksie008]

Hi all,
I've read the whole thread and I noticed that a lot of people have somewhat the same problem in not getting a gps-fix.
This is what works for me and a couple of my friends who also own a TP. We all have the original HTC rom.

-Do a hard reset. After hard reset, don't make any tweak settings
-If possible, download the the gps-data with the quickgps
-Install tomtom 7 (I tested this with 7.450, 7.451 and 7.910 - all works great)
-Open Googlemaps and pinpoint your location.
-Go to menu and thick use GPS...wait till you get a gps fix (you should get
about 5-8 satellite fixes)
-Do not close googlemaps after the gpsfix. go to the homescreen
-start TOMTOM...in a few seconds (between 5-15 secs) you'll get a fix with
the internal GPS.
-Then go back to the homescreen, open googlemaps and close it.
-Go back to TOMTOM, you'll notice that the fix is still there.
-Restart TOMTOM and test if you still get a quick fix.

as far I can see, the lag is still there, but acceptable (about 5 meters).

I hope that this works for all you guys who still have the gpsfix-problem

This is not an acceptable solution my friend. First you need a manual (with your post) to do all this every time you need navigation. Second when you get TT7 working you will be already at your destination. :D
Thanks for your effort but we need a real solution.

This probably isn't a real solution but it would be interesting tough if this is a interim solution for more than one person. If so I think that would get us much further to a real solution.

But you certainly right - I wouldn't want to do the whole procedure above every time I want to use gps either. ;)

[doksie008]

This only has to be done once and not everytime you start tomtom.
Btw, this works for us and it's only a suggestion. If you don't try it, you won't know it if works for you.

[wibberly]

I returned my Touch Pro to HTC for repair on 27/10/08 because of poor phone signal and even worse GPS signal. Before I returned it a lady on the phone went through a series of tests for me to try before I sent it back.
She agreed it was faulty. I also informed her I have a HTC Diamond on loan which is faultless in every respect so I could even do a side by side test as well.
I have been watching the live HTC repair tracking website daily and after about a week of the same message 'Hold for Engineering' I decided to ring them to find out what this meant.
I was informed that indeed a fault had been found and they were waiting on a part. I asked him to confirm this again as I don't think English was his native language just to confirm. Great!
After watching the same message on the website for about another week I rang them yesterday to see if I would be getting my phone back soon.This was on the 10/11/08.
I was phoned back today to be informed there is no fault that could be found and the phone is to be returned to me in the next couple of days.
I told them it is a waste of time even returning it if nothing has been done but they told me to try it and see and if it is still not working then to return it again. We will be on windows mobile 7 by the time HTC acknowledge a problem.
I have an email. HTC Customer Satisfaction Survey. Do you think they read the replies?

[eras2r]

I use Garmin Mobile XT and I was having a hell of a time getting the GPS to work reliably on my new Fuze. It took forever to lock onto a GPS signal, and when it did, you could see the GPS signal drop to 0 about every 5 seconds. I believe this is what was causing my lag while driving. So, inside of the Garmin app under the GPS settings, it was set to COM4 Serial. I disabled that and changed it to use the "Intermediate GPS Driver" and everything is working great now.

Locks onto a GPS signal quickly.
No lag while driving.

Could the problem possibly be the GPS driver/chipset not working properly with the COM4 serial interface?
Is the "Intermediate GPS Driver" part of Windows Mobile or Garmin?

[illegible]

I've been through at least 5-6 programs (including tracky, GPS Tuner, GPS Today, gps phototagger) and all had horrendous acquisition times, from 5-15+ minutes. Then i installed Beeline GPS (http://www.visualgps.net/BeeLineGPS/default.htm) and suddenly i'm getting really fast acquisition times (5-25 seconds, usually on the lower end!)...

Does anyone know why? It did seem to go through some process of finding the gps that others did not, could it have found a better way of communicating with the gps than the other programs had as default (com4 i think)? and if so, how can i get my other programs to use the same way of connecting? It actually works the way i'd hoped it would.

I don't know about the lag, i don't really use and lag sensitive applications, so it's hard for me to know if it fixed the lag or not.

I'd be interested to see if other have had the same experience or if there is something else going on (it's been consistent enough to know it's not random, and i didn't change anything else, so i can't imagine what else it could be)

Thanks!

I use GarminXT too. However I found it to be really reliable even using COM4.
First lock - 10-20 seconds
After that lock time is 2-5 seconds.
I'm finding my lock times are very similar when using TT7 but it does seem to drop out every now and then.

I also prefer the user interface with Garmin, but thats just a personal preference.

The only thing I am unable to get working is the Bluetooth sync with my car stereo. When i had a Nokia N95 the voice guidance would come through the stereo speakers (very handy), however I can only get speech through the phone speaker on my TP. Any ideas?

[iamwarpath]

I have a stock Sprint HTC Touch Pro. I am not using any external GPS chip or reciever, just what is built in. I put Iguidance 4 on the phone and there was so much lag that I would miss my turns by two blocks then miss the same turn again after I have made a U-turn. I thought it was the software so I removed it. I am currently using Google Maps + Live search. Both pieces of software put me 15-40 feet away from where I am standing. Yes, standing. It has to be something related to the phone like every has already said.

I upgraded from the HTC PPC 6700 with a i.Trek M6 external GPS chip and Iguidaince 3. Comparing them side by side, the i.Trek puts me in the exact spot I am suppose to be in while the TP moves me around and says I am across the street.

I just filled out the email us section of HTC's website and will try the GPS driver update and CAB file later. I'm not going to flash the rom though - I've had bad experiences with my PPC 6700.

Unfortunately we have all fell prey to HTC and bought their phone..... maybe we should all return it then maybe they will listen....

It's interesting how corporations deny culpability a lot of time when even by just acknowledging it and saying something like "we don't have a solution yet but we are working hard on it..." Just admitting a problem i guess is a foreign concept for a lot of management...

[Flying Kiwi]

Unfortunately we have all fell prey to HTC and bought their phone..... maybe we should all return it then maybe they will listen....Although I bought a TyTN II when they first came out, there were no adverse reports or reviews around at the time (although I was disappointed with its video playback capabilities when First used it). I've been following this forum purely for general interest sake.

[thedogger]

I'm using iNav 4.02 with the AT&T Fuze just fine. I used Franson GPSGate to provide the intermediate driver abstraction -- take COM4 as the input, and set COM1 as the output from GPSGate. In iNAV, set it to listen on COM1, 4800 baud - seems to work fine on the stock AT&T Fuze ROM.

iNAV worked fine in Windows Mobile 6.0, but in all 6.1 ROMs you need GPSGate to make it work. Otherwise you get this horrible screen lag, low frame rate problem where the map screen doesn't update.

Note: I have A-GPS disabled - iNAV stalls for about 2 minutes if there is an active data connection running when it launches, and A-GPS makes a data connection when you fire up the GPS chip, so you have to disable A-GPS.

[iamwarpath]

I didn't know the difference between a-gps and gps. I just expected it to work the same as an external gps device.

http://wmexperts.com/articles/gps_vs_agps_a_quick_tutorial.html

I have noticed that the a-gps of the Sprint Mogul is better than the newer TP. The Mogul isn't moving around like it is trying to triangulate where I am. Isn't it suppose to be the same chip?

[alfakilocharlie]

HTC doesn't seem to reply emails that are sent to them. They seem to respond better to calls.... I just had a HTC rep call me, and according to him, the Touch Pro and Diamond is not compatible with any GPS software, even if it's meant to be. The only one compatible is Copilot, and that's all. Even Google Maps is said to be partly incompatible. *Then what is Google maps for? Just for display?*

I used to have GPS lag issues, with TT7 showing my position 350 metres away from where I actually am when stationary and when I was driving (Imagine driving across parks, rivers, and buildings). Now, it's gone, and I'm still having a slow GPS fix.

I did use a cab file a few pages back, but nothing seemed to work, so I did some reg tweaking by changing values of this and that, and it seems to solve the problem, although TT7 still updates my position 15-20 meters slower than my Nokia or the TP with an external BT GPS.

[starstreak]

I guess I should consider me lucky.
My TILT(unlocked and duttyrom) normally takes 3-6mins to get a cold fix. Hot fix can take 15seconds to about 2mins. I can get a fix indoors sometimes, and it seems to hold lock unless I'm in the city, where I need it the most. Once it drops, takes a few mins to get a lock. Needless to say, I was ticked when I didn't know where to turn next.

The Fuze, takes about the same for both hot/cold fixes. I don't seem to have the same pulling strengh to get a fix indoors. BUT I can get more connections. like 6-9 sats, when the Tilk got like 3-5. BUT I can go from 9 sat locks, to nothing, by moving the Fuze from my right hand just above my dashboard in my car to my lap. BOOM. Nothing. Grrr...

Oh to stay a bit on topic, I do notice, that with igo or TT, my position is about 2-3 car length behind of where I think I should be on the 3D map.
Btw, if you use igo, don't use the show where you are pinpoint when driving. Drives me bonkers to see the DOT like in the incoming lane, when the arrow is where it's supposed to be. Yes, I know, its probably that the mapping software isn't 100% perfect of where the road should be. And yes, at the time, the program says I have excellent sat lock.

[xeryus1907]

Hey Guys,

My TP have lags and cant get cold fix, the fixes it found always disappears in a few seconds, not stable.But my friend's tp gps works like a charm and with my globalsat ext. bluetooth gps receiver it works like a charm too.Both of them with the same softwares.

What do you think about that?

[Jouke74]

For all people having done the startpost tweaks, especially those who have issues with the cold fix afterwards, please see how it works if you only UNDO this tweak:

- Drivers\SleepOnNoData -> 100 (default is 1000)

My interpretation of this registry key (which is nowhere to be found on the internet) is the time in milliseconds it takes before the device goes back to sleep when you are not getting any data from the satellites.

I have tried values of 100, 500 and 1000 together with the tweaks on the first page (512 buffers plus the PollInterval to 100). And for lag in update speed this "fix" does not seem to matter (much) (Note that I left AGPS and logs on, but that should not make a difference IMHO as it should not influence the GPS driver?).

However when your Gps receiver was off and had no fix at all, and then you turn it in on for example on Google maps the first time, the time it has to locate satellites is reduced from 1 second to 0.1 second. If it fails to find any satellite in that time (which is not uncommon with 0.1s) it will shut itself off, hence no cold fix or working GPS at all.

With "100" I was not able to get a cold fix frequently and Google maps indicated GPS looking for signal way to short, with 1000 this is no problem at all. It gets a fix, although this takes some time (depending on Agps, QuickGPSfix and currentl location as compared to where you turned your GPS off last time). Once it has a fix, the other 3 registry tweaks help quite well to increase the speed, I think namely the polling interval tweak matters.

Now the other thing that worries me, that with the Polling interval at 250 and the SleepOnNoData at 100, it would mean that every one pollinginterval your GPS device is turned off and on for at least one time (depending on the amount of time it takes to transfer data). I don't think this is good. I think the sleep value should be at least equal to the polling interval.

PS. Thanks for the lag issue solve btw.

I have finally managed to get this working well. I contacted HTC several times but they were frankly completely useless. When I received the handset it was not picking up any sats using TT6, GPS Test or HTC GPS. I tried the .cabs at the start of this thread but they made no difference. Thus I decided to take a chance and upgraded the radio as suggested on a previous post. I think my original radio was .18 or .19 and I upgraded to .28. I instantly had one more bar of reception and better 3G connectivity with slightly better call quality. After this the TP could pick up between one and three sats under clear skies but would not get a lock. I then changed the Quick GPS settings to allow automatic updates (previously everything was unchecked) and upon the next attempt GPS Test locked on to several sats very quickly. Now TT6 works well in the car and is also adequate on foot as long as you are walking briskly. However, there is occasionally some lag in both scenarios when the sat signal is weak.

Many thanks to all who posted advice.

I exchanged my Fuze this morning because of GPS issues, and now I got one with a bad USB connector + bad GPS. I can see 9 satellites within 60 seconds of starting GPS Test, but none of them change from yellow to green for longer than 1 second.

When I get Fuze #3, I'm gonna try every single radio available just to rule that out.

I exchanged my Fuze this morning because of GPS issues, and now I got one with a bad USB connector + bad GPS. I can see 9 satellites within 60 seconds of starting GPS Test, but none of them change from yellow to green for longer than 1 second.

When I get Fuze #3, I'm gonna try every single radio available just to rule that out.

Just one question, did you disable A-GPS?
If not then that is most likely to be your problem! :)

I have this exact same problem. GPS test gets 8 bars of satellites, and about half will go be green and half will be yellow, but they switch around about every 10 seconds. I've only been successful once in getting a lock in GPS test and I never again could replicate my results. I've tried all the roms, stock att, romeos, and pdaviet plus I've tried the 28 and 32 radios plus stock spl and hardspl with the stock rom. I've just resorted to my Holux M-1200 for gps now, works great with tomtom and usually locks into the satellites before I can even get my stylus out to open up tomtom. Just wish the gps I paid for inside of the phone would work correctly.

Pretty much the same here. I've tried the Romeos 1.4.1, and flashed the radio to .28, but all I get is maybe 4 or 5 satellites on GPS test, with a couple of them green, but I can't get GPS working in either Google maps or Tomtom Navigator 7. It's pretty disappointing that there's so many issues with this - I just cant seem to get GPS working how it ought to :confused:

I'm using iNav 4.02 with the AT&T Fuze just fine. I used Franson GPSGate to provide the intermediate driver abstraction -- take COM4 as the input, and set COM1 as the output from GPSGate. In iNAV, set it to listen on COM1, 4800 baud - seems to work fine on the stock AT&T Fuze ROM.

iNAV worked fine in Windows Mobile 6.0, but in all 6.1 ROMs you need GPSGate to make it work. Otherwise you get this horrible screen lag, low frame rate problem where the map screen doesn't update.

Note: I have A-GPS disabled - iNAV stalls for about 2 minutes if there is an active data connection running when it launches, and A-GPS makes a data connection when you fire up the GPS chip, so you have to disable A-GPS.
Thank You Bro.

I did this and my Fuze is just working fine with i-Go 8 :D

[vijovame]

and did this too....

THE SOLUTION: Turn OFF aGPS!
a) Start->Setting->System->AGPS Settings
b) Uncheck BOTH "Enable AGPS" and "Enable AGPS location information..." (under the Privacy tab)

Awesome. I did all off the previous tweaks and still had issues. After deselecting the AGPS under the privacy tab I consistently get a lock in 5-15 seconds. WHOO HOOOOO!!!!!

Made a difference for me too. That's the first time I've seen the second AGPS setting referenced!

Unfortunately, there is no "AGPS Settings" item in the Settings->System Tab on the Sprint Touch Pro. Would disabling AGPS fix GPS lag issues on this device too and, if so, how would we disable it?

[Aar0n]

I've got my GPS working now after not getting a fix for ages before. I just left GPS test running for about half an hour to lock onto 7 satellites then get a fix.

Now it's done this I get a fix from 10 seconds up to a couple of minutes in a large apartment block.

TomTom 7 works alright too, but it's slightly behind still (even with Baud set to 38400 and Other NMEA receiver selected, too.)

[olegplanets]

I read all 23 pages and unfortunately wasn't able to get my HTC pro working. I got my htc from Bell Mobility in Canada. I made a complaint through BBB.
And I also do no have the AGPS in start-settings-system. Is there a way to disable it otherwise?

AFAIR there is an option to disable AGPS in Advanced Config. This should work for you.

I wonder if its only affecting a certain batches. My GPS seems to be weaker than my Tilt since its difficult to get locks indoors, but with both Garmin XT and iGo8 I don't really seem to have the lag problem...if I do its not very noticeable.

[drunkbastard]

From my own personal experience with the GPS lag, I put the 25.16 radio on, and I get no problem with either time getting locks or a lag. Took a few radios, but I found that one works. YMMV of course, I'm in Phoenix if that matters.

But these radios do not work with the Sprint Touch Pro correct?

[mobiletrader]

For those still fighting with finding the location of the right settings on the Sprint version of the phone...

The AGPS setting can be turned off as suggested via Advanced Config.
Don't forget to turn on the Location Service via
Settings > Personal > Phone > Services > Location Setting > On

I don't know when/how that got turned off the first time for me, but in tinkering with my phone, this service was turned off by default after a hard reset.

[i00]

changing these settings didnt seem to make a difference for me :(

[jwb1969]

Knock on wood. I have had success with Pocket CoPilot v6 and Google Maps.

Only real complaint is on the few times I used it, I had slow sat pick up times. (1-2 minutes) Other than that GPS seems to work for me now.

Now that I just jinxed myself, let me go check it again. :D

I have tested the GPS using TomTom 7 and IGO8 on Fuze and dedicated GPS unit running TomTom 7 and IGO8 side by side.

-- Fix takes considerable longer time on the Fuze.

-- Driving at 60-65 MPH there is 2 sec lag on Fuze compared to the dedicated GPS units both on TomTom and IGO8

-- Using GPS test helps getting the fix quicker on Fuze.

[hopper13]

There seem to be widely varying reports of time to signal lock for those using the GPS function of their touch pro's. My own times often vary widely. In an effort to understand the differences in reported times I'm starting this thread. Please do not post here if you cannot get a GPS signal or are having software difficulties including lag, there are other threads for those topics. Thanks.

My experience today... time to lock 14 minutes. My settings as follows:

1) Sky clear.
2) Fresh soft reset.
3) Freshly updated QuickGPS.
4) GPS settings, COM4, Hardware port: (None), Baud rate 4800.
5) AGPS off everywhere.
6) Software, TomTom 7.9, GPS set to "Built-in"
7) ATT Fuze, stock rom and radio.

[mrvanx]

1) Sky clear
2) Any time (normally phone is powered on 24/7)
3) QuickGPS not used at all
4) COM4, 4800bps as normal
5) aGPS off (not sure if it is supported in the UK yet?)
6) TOMTOM set to built in, googlemaps set to auto
7) VERY FIRST fix after a hard reset or rom flash takes a while to get the ephemeris data (since i dont use QuickGPS) but fix after that takes around 20 seconds depending on if the car is moving or not.

I do get GPS lag though, not too bad.

[dgduris]

50 seconds!

Process - run 6 days ago:

1. Run GPS test until you get a lock (took 20 minutes plus)
2. Run Google Maps

I did the above one time the day I got my Fuze. Now I get a GPS lock with Google w/o doing anything but starting up Google.

aGPS is enabled
I have run the GPS Quick Update Utility once and am getting 50 second time consistently when in the car. I have set a car profile that automatically launches Google Maps so all I have to do is tell it to use the GPS.

There are already two threads about speeding up your GPS lock time, i'm going to merge this thread with one of them.

Update: Merged with TouchPro GPS Lag Problems

[misfitwrx]

I am buying an att fuze in two weeks and im getting all my tweaks and software all ready now. i was wondering if google maps is usable for navigation? i know it doesnt have voice prompts or anything like that but does it reroute you if you miss a turn and stuff like that? if its not a good navigation solution what is a good nav program? i live in the US so igo8 wont work will it? i think thats only EU

With all due respect, this is a thread about GPS lag problems, not GPS lock problems. Granted, it has migrated all over the place. I was trying to segregate the issue into a descrete thread so that people can try to isolate the operator causing the issue. No big deal, I guess.

FWIW, after using the GPS all day I did a soft reset and still got a lock after about 40 seconds...so that's not what causes the occasional 12-20 minute lock issue.

[kwill]

im with notatreofan. i might be exchanging my fuze. damn thing hasnt locked a satellite since i got it and i know how to use it and all the little tricks from my kaiser days. tried two diff roms, two diff radios for the rapheal and one for the diamond. still no luck. ive let it run for about 10 mins during driving at still no lock. sats pop up for a second as green through gps test. then turn right back to yellow and this is on a CLEAR day! tried the tweaks mentioned, ALL of THEM and nothing. this blows and i cant take it anymore:D

**EDIT** so, freaking hilarious! i was driving home and decided id fire up gps test right before i left the building. started driving and about 3 mins later i look down and i FINALLY had 3 or more green bars. fired up gooplemaps and lock and tracked me in no time. not much lag if any either. anyways, safe to say it does work at least. and i cant attribute it to the radio i changed to (latest diamond), tweaks in this post, numerous gps tools or what.

If you're looking for a free program with voice prompts, 3D moving map view, etc., take a look at AmazeGPS.com. I've only been using it for a few days and only on short trips where I already knew where I was going, but it seems to do the job very well. It does do real-time rerouting if you turn off the planned track. It seems to cover most of the world; the maps and POI database seem pretty good for my part of Massachusetts, at least (can't speak for anywhere else).

Hi Guys,

i have still lag problems.

my tp gets 7-8 fixes in 10-20 secs. but they disappear in a second then they appear again.everytime like this.Now i give up to use my internal gps, i use my globalsat bt gps receiver.

i ve tried all settings, tweaks, programs and some radios except roms but i couldnt have a solution yet.

what did you or people have my problem do?
you give up like me or you solve the problem?
