GPS in HTC official ROM doesn't work

Hi All,
Could someone please let me know how to use the GPS in my phone. I have tried upgrading the phone to different ROMS that were supposed to enable the GPS and now I am currently using the official HTC WM6 Australia but I cannot get the GPS detected in TomTom or Google Maps. Any help on this would be very, very appreciated since one of the reasons because I bought the phone was because of the GPS...
Thanks in advance

what settings are you using for your TomTom?
Does it say "No GPS Device"?
If it says "Waiting for a valid GPS signal", then you just gotta walk outdoor and wait a few mins...
Note that it takes quite awhile for the first lock.

please state your radio version as well

GPS Problems
Hi,
Windows Mobile 6 Professional (Build 17944.0.3.1)
ROM. 3.00.707.17
ROM Date 06/29/07
Radio Version. 1.38.00.11
I use the "Other NMEA GPS receiver" /115200 GPS baud rate /GPS in COM9
and it says "waiting for a valid GPS signal..." but I have been outside the house waiting for 20 minutes and it doesn't pick up the signal. My TomTom bluetooth GPS used to pick up the signal in 1 minute.
If I get this GPS running, how long will I have to wait everytime I want to use my GPS?
Thanks

sounds like a tom tom configuration issue.. .there are threads for this in the forum, cause your radio and rom are up to date.. (although i'd suggest a newer radio to get rid of battery drain). It definitely shouldn't take 20 minutes.. i think within 4 minutes it should be set, most of the time MUCH quicker (2min?)

Where can I get the radios
Sure, where can I get the radios updates?
Are all compatible with all the different ROM versions?

I had similar issue with Tomtom recently. After I have TomTOM software downdgraded back to version 6.010 instead of 6.030 problem is gone.

First of all, your GPS device IS detected. There is too steps when Tomtom is trying to make a GPS fix: 1) no GPS device 2) waiting for a valid signal. If you've already reached the second one it means Tomtom can sense your GPS but it cannot aquire the three satelits signal required for a valid location fix.
I would suggest you upgrade your radio. Athough the 1.38 one can work, I didn't have a good GPS with it and it tookme ages for a fix, and sometimes no fix possible.
Besides, that radio wasn't made for the newest wm6 roms.
1.46 will work way better for that.
And since Tomtom is not the lightest application for GPS testing, I would suggest you try other apps such as GPS test (which is free etc.) you'll get a fix quicker, and once you had a fix, all other applications will fix instantly too.
You can try the GPS function in the camera too, which is quite light too and fix quicker than Tomtom.

GPS Not working

Did you do a hard reset AFTER flashing?

yep, it happened to me also, an hard reset should resolve, in any case I suggest you to install the utility "GPSTest" (google to find it).
that program is useful because it is able to "renew" the gps status, after installation just launch it (outside of course) and let the program to automatically check your GPS status (1st time it can take 2 or more minutes), when you see at least 3 sat aligned simply close the program, shutdown the phone (NOT soft reset) and then after reboot launch tomtom and you'll see that it will recognize again the gps module.
bye,
davide

i dont think it is fault that you did not do a hard reset after flashing your rom, neither did i.
You should run the htc gps tool with cold start for a while (3-4 mins minimum), then ur TT can find gps.

The same story here, except that I used GoogleMap. It took a long time for GPS to get a fix and when it did, it found only a few satellites. The reception was also poor with a lot of lagging. And yes, I forgot to make a hardreset after flashing.
I just installed http://www.efficasoft.com/gpsutilities/index_wm_ppc.html and this program got an immediate fix to 12 satellites. I then rebooted and noticed that also GoogleMap was OK now. Why? Someone else may explain.
Untick "Auto search Bluetooth GPS receiver"
Set "COM Port" to COM4.
Set "Baud Rate" to 4800.

hello everybody
im having a very wiered problem since today, i have flashed the new 1.93 NLD stock rom, and the gps decided not to work anymore, i did everything possible, hardresetting, reflashing the rom, but nothing helped, i also installed this HTC tool, and let it running for a while, nothing changed, i deiced to leave google maps runnign for a while, it turned a message saying that my GPS device is having torubles finding a GPS signal.
does that sound familiar to anybody,,, actually what makes it wierede, the programs can see the GPS chip, i mean in tomtom and google maps, but only the device, no signal.
Best regards
Kevin

Always remember to do a hard-reset after installing a new rom.
- I have tried several times that my gps were "stuck". My sollution is the Htc Gps tool (Find it here: http://maritime-billeder.dk/htc-diamond.html). With that you can choose to do a warm or a cold start. This gives the gps chip a kick, and almost always fixes the problem.

GPS connection dropping?

Hi, I tried TomTom today and my GPS connection kept dropping every 5-10 seconds....I'm using the original radio ROM that came with Orange, do you think upgrading it will help?
Thanks

agps
I had the same problem and solved it by disabling assisted GPS using Schaps Advanced Configuration Tool (http://forum.xda-developers.com/showthread.php?t=418151)

radio updates
I have updated my radio to 1.00.25.05 and 1.00.25.07 and my orange diamond kept dropping GSP ever 30 seconds or so I have now gone back to the original radio 1.00.25.03 and worked without any problems today

Hmmm good point, I will try that thanks.

Had similar on sunday drove over 150 miles and it was perfect in garmin xt first time i had used it on my diamiond, return journey had the dropped signal problem only sorted after selecting different driver in garmin - strange stuff! never had this type of problem on any of my wm devices.

:O
The same happend to me also... My stock phone was shipped with the .05 radio I updated the radio to .07 and the GPS kept disconnectiong. I flashed back my .05 and will try it now.

I had this problem, untick receive all incoming beam and that fixed it for me

now that would be a new dilemma: how exactly is the GPS receiver and transmision affected by a beam ?

I'm walking allot, so I don't need to have my Diamond turned on the hole time (mostly in my pocket).
but when I turn it off an then on again, It takes a real time to research the GPS satellites, it works but a waste of battery or wait time.
My question is, is there a tweak that the GPS is not turned of when the screen is blanked.
like the GPRS; I still receive emails when the screen is off (blank)

GPS Problem

Hi,
I am using the original ROM 1.93 and I have installed Destinator 7 with Greek maps (2008). I don't know why, but the GPS loses its signal instantly and then everything is fine. This happens after a certain number of seconds and it is repeated.
Does anyone know hot to fix this?
Thank you.

I have had the same thing.
Turn OFF your AGPS with advance config.
If that doens't help, give it a hard reset.
cor

try with radio .07 (you wont loose anything), it catches gps signal quiker...
bye,

Here is my experience, where I noticed the GPS problems disappear completely.
From day 1, when I got my Diamong, first thing I did, without testing the GPS with shipped older official ROM, was to flash to SwiftBL ROM ... great ROM I have to say. But then I noticed that I had fix-no-fix-fix-no-fix (lags) problem, as well as the fixing itself taking up to 10-15 minutes. I tried newer SwiftBL ROMS, tried switching A-GPS, tried using .07 and .08 radios .... nothing, problem persisted.
I went back to .05 radio, and this time flashed with Dutty's Full v2 ROM ... very very fast and neat ROM. The ROM has A-GPS switched off from start. I did one hard-reset after flashing ROM, as Dutty recommends, and guess what ... no lags and fix within 10-20 seconds.
What was the problem .... I sinserely do not know, whether the combination of ROM+Radio+A-GPS! ..... main thing being now my GPS is fast at fixing, signal quality high and no lags.
Hope this helps.

cpootjes, because of the work load I managed to visit the site today!!
I activated A-GPS after a hard reset. I didn't even think that this could be a problem! However, I will test it and I will post the result..
Thanks anyway..

cpootjes, having activated A-GPS caused the problem (as you told me)..
Thanks again !!

Folks, since you have Destinator 7 installed and running, I hope you can help me... I cannot get mey Destinator Portal to see my internal storage, so I can install my maps there. Any suggestion ?

Diamond GPS Issues

Recently I updated to the SwiftBL 7.0 Full 16PP. As I start TomTom 7.450 I says it has a gps device and then it says it has lost is gps signal.
After 15 seconds it updates it's gps location and tells me again it has lost it's gps location.
Then I close TomTom and start QuickGPS and update it (it is still valid for 6 days and more). After this update there is no problem with Tomtom anymore.
This updating I have to do every time I want to use Tomtom.
I'm just sitting in the car and not in the bathroom, so the gps is not the problem. I'm having this problem for a week now.
Does somebody else have this problem too? Is there a solution?

Try holding it up next to the window or use an in-car cradle. This has happened to me when I hold it next to my lap in the car I cant even get a fix. When I hold it next to the window I get a highly accurate fix.

I have a cradle stuck on the window. Before (for 3 months) I did not have a problem.
Or my hardware is braking down or there might be a issue with the ROM. Also f*ckup on my part is possible ofcourse.
But I wanted to know if I was the only one that had this problem. Until now I think I am.

i have gps problem too but i think using htc tools solve it for me so far...use the clear memory option together with nav init and wait for mode 2d fix.Try tis to see if its work?

Please mention which radio version your are using. Please update your radio to Radio v1.00.25.07. This is the best version for the GPS

I too used .08 before. I never got a fix. It detects all the sat's but won't get a fix. Then I downgraded to .07 & voila.
How was the GPS when u had used .07?

I have the same problem.
My solution : soft-reset my device.
I'll try another solution : disable the A-GPS.
If anybody has another solution...
(I don't want to change my radio because of the warranty)

A-GPS
I had that same problem with iGO. Disabling A-GPS did the trick.

Likewise with Tomtom. A-GPS is the guilty party.

Having the same problem in Igo 8. The problem is that the program looses the GPS in 5-15 seconds all the time. Igo sais that it is loosing not the signal but it losses the GPS module. The only cure i found is a hard reset or going into flight mode. In flight mode the GPS works perfectly. Tested on 2 Diamonds. Any suggestions except flashing the radio??

100% A-GPS thing
Disable it whit Advance Config

Thats weird I got my XDA Ignito yesterday, put tomtom 7.450, in advance config it had a-gps disabled, but TomTom would not pick up anything.
I thought I try to enable it and it suddenly started working and it was working indoors too.
Thanks for all the info.

thanks a lot, i`ll try.

Yes that did the trick. I did put an other ROM on my Diamond so I fixed it by accident but now I know the reason. Thanks.

i cant get a fix on .08, reverting back to .05 or i will try .07

Yes! Exactly! I have seen same problem as topic starter. Also If I check "GPS status" by TomTom menu, it always lost and found GPS device every 5-10 sec. Only one think helps - start Google maps app, enable GPS, then Google map quickly found satellite I start TomTom and TomTom work fine till closing.
After disabling A-Gps, now TomTom work perfectly.
