I tried everything, different ROMs, Radios, Tweaks, Workarounds, Navigation Softwares.........

Nothing helped me. I was very frustrated.

After all this I found the solution that solved all my GPS problems.

I tested the HTC tool:Nadavi_HTC_GPS_TOOL.cab

With this tool you can do 4 types of reset on your integrated GPS modul.

I tried all.

It seems to me that the one that fixes the problem is: Clear memory

1: You have to go to a location with a good GPS signal. Than start Clear
Memory in the Settings TAB.

2:After that look at the Information TAB: At GNSS DOP and Active
Sattellites, if get an update at Mode 2 you are done.


After this procedure all my problems are solved.

I have now a time to first fix about 30sec.

No GPS LAGs, the positioning is now very exact.


So if anybody have the same problems , try the HTC GPS Tool.

Hi, I will make a try, how to make a warm, cold and hot start ?
Cheers

In a german PPC Forum, I get a tip that a RADIO ROM in combination with a bebeROM should be solve the problem. I flash it and test it now and report to you guys.

Open the HTC GPS Tool. Choose your Option e.g. HotStart <<<< klick Open

Thats it.

I use Version 1.1.1.0 of the GPS Tool.

It worked for my diamond with A.Z.T.O.R. SprintFlavor ROM and radio 1.00.25.08
This is the first time that I can actually use TomTom.
Thanks for this handy tool.

I worked for me also for official 1.93 ROM Russian
Tested on iGo8 and 2 local GPS Nav programs
All of them are very responsive and accurate, really amazing
Instead of 20 minutes I get a fix in 30 seconds

However, it seems that QuickGPS ruins everything when it downloads sat info.
I turned it off, and will check later today/tomorrow

So far I am very optimistic

maybe...i'll try this too....
anybody knows if clean memory clears also QuickGPS ?

I will guess that "clean memory" also cleans the data QuickGPS downloads.
I cleaned memory yesterday in the evening before driving home.
GPS was fast and accurate after that.
I also tested it in late evening and today in the morning before I came to work. It was quick.
Then at work I connected to my laptop via Activesync (and I have an option "load satellite info automatically if connected via ActiveSync" in QuickGPS) and when I tested GPS in the open air at lunchtime it seemed to be slow again ( I waited ~ 5 minutes).

My conclusion so far - QuickGPS downloads garbade or unappropriate data

So unticked this option in QuickGPS and will test again to be sure that this is exactly Quick GPS who does this dirty trick

I will guess that "clean memory" also cleans the data QuickGPS downloads.

yep, I've the suspect too that quickgps data aren't correct or a bit outdated.

I discovered also in the official telus diamond forum that IP addresses registered are different from the ones (traditional) recorder into quickgps app (there is a registry key for this)

Bye,

Do you know which registry key exactly ?
It will be funny to check if they are all the same for different countries or vary from country to country.

Its much better after disabling QuickGPS and cleaning....
but i still got some minor lag (2 lengths of Arow)
