Hi,

I dont know if this is pure fluke and this just works on my setup but i seem to have found a way to get a 5-6 second fix GPS, having said that i cannot guarentee that it will work for everyone, but you are all welcome to give it a go!

Firstly i will list my setup:

SwiftBL WWE v6.5 16Mb PP (http://forum.xda-developers.com/showthread.php?t=408109)
Radio v1.00.25.07 (http://rapidshare.com/files/136644831/Diamond_Radio_1.00.25.07.zip)
TomTom Navigator 7.450.9028 for HTC Diamond

Process Used:

1: Load TomTom 7, and wait until you get the message "Waiting for valid GPS Signal" at the bottom left
2: Once the message appears select "Browse Map" -> "Find" and go to the page with "My Location" this will be greyed out.
3: Exit TomTom 7
4: Restart TomTom 7, once you see the message "Waiting for valid GPS Signal" it should fix

As i said previously, i dont know if this is a fluke, but i have had 100% success with this.

My Testing:

Everytime i have done this i have done this from different locations 30 - 40 minutes appart (I travel alot on the train) so my device has not been locking onto the same satelites

To ensure fairness in these tests i have powered down my device totally, started the device from cold, entered my PIN and loaded the desktop. Then launched TomTom 7

I have tryed 5 different locations in the UK over 2 Days:

Southport, Manchester, Bolton, Churchtown and Preston

I've never had a problem getting a fix with any of the diamond roms - often as quick as 5 or 6 seconds depending on where I am.
The issue that I think most people are having is the lag in providing an accurate fix.

Im jealous!

Until i started doing this i was getting 1-2 minute lock on and fix my position, but as i said this seems to speed it up alot for me.

Also, there is no lag to get an accurate fix doing the process i suggest, once there is a gps signal detected, my location is zeroed instantaniously!!

My experience is as follow (I tested a lot):
With radio 1.00.25.05 cold fix takes about 5 minutes. After that a few minutes. Once I get a fix, it's stable.
With radio 1.00.25.07 cold fix less then a minute. After that about 5 seconds. It's also stable once I get a fix.
Quality of calls is the same, so is the signal strength and battery life.
So I would recommend radio 07 for those who use navigation.

It is weird indeed. I have 05. Sometimes I get a fix in 5 secs, sometimes it takes forever.

I also found that once I get a fix the accuracy fluctuates from poor to high indeed.

Once I hit the roads, np but need to do more tests

I would definately update your radio to .07, i have much better signal in general and GPS is much better

I have had the same problem as yours with those details...

I think it maybe to do with the ROM, mainly because I have not had an issue with other roms...

Hi everyone,

I try Radio .08 and the same thing. I fix GPS in 5-10 secondes...
Some people say that with the .08, less batterie is consumed...
I don't know need to do the test...

I try Radio .08 during 4 days, and my batterie is good !
My phone is charging during 1h30 - 2h and it's full...
less consumption, but when i use GPS.... my lifetime is very short....
No lag ! but high consumption.
I can call and use 3G, during 1,5 days !
