GPS Fix Problems (official HTC ROM)

i have problems with Satalite FIX.
it can take mor then 10-20min (if at all) to get a fix.
i setup my GPS manualy to COM9 @ 4800.
i know (at least) one other user have a simular problem.
HTC, after some e-mails, say that if i DON'T use TomTom software, they can't help my with this isue.
any idea ?
thanks.

Fix
I had some problems with slow fix. I enabled the GPS applet in settings and it was configured at 33600, changed to 4800 and also in Tomtom and miomap settings configured to 4800, after that, very quick fix, on cold start less than 1 min, on warm start just seconds. Try it.

under, settings -> connection -> GPS ...
i set:
program tab:
GPS Program port = GPD9
hardware tab:
Port = com9
boud = 4800
access tab:
mark on the manage GPS Auto.
is taht OK ?
and allso on the navigation program i set manualy com9 @4800

Yep, that's my config and works right...

interesting... i have my settings as follows -
program tab:
GPS Program port = GPD1
hardware tab:
Port = com1
boud = 115200
access tab:
mark on the manage GPS Auto.
with these settings i get a fix in 30 sec to 90 sec...

After a sofreset? Probably not
The "warm reset time" in a GPS is not related with the Port number or the baud rates...but with its sensibility

SAme for me the GPS response can take up to 10 minutes.
I tried your setting Julioski and AriebK but it doesn't help?
In tomtom I don't see where to set the port and the baud speed can you help?
Any other ideas?

after configure the above settings, i get FIX, but after 20-30min of navigation... the FIX is gone, one more thing, i notice that my phone 3g signal drop allso, SR was nedded.

According to HTC the reason the GPS function was not enabled in the first place was a conflict with the GSM signal,anyway try manually setting your phone band to GSM and see if that makes a difference.(Settings,phone,band,select network type:GSM)

What radio version have you installed?
1.35, 1.38???

I have an HTC p3600 Trinity and have also just installed the newest ROM from HTC.
I downloaded the TomTom application from HTC, installed it and everything "seems" fine accept I cannot acquire any signals.
I have tried many of the different GPS settings from the GPS manager, but nowhere do I see a way to change what TomTom is looking for. There are 5 default gps reciever options... (builtin, bluetooth, wired, other bluetooth and other NMEA device) and I really have no idea what to choose if I have to input the settings.
Can anyone help?
Thanks!

Both the "built in" and "COM9" should work (and do for me).
Make sure you're in an open area, and give it enough time to acquire a signal (could take 10 mins).

i tryed that... seems that with GSM, it took much more time to get a FIX (if so)...
with GSM it get the FIX much faster, but stil... too much and it drop the signal without any reasone.

I have the same exact problem, sometimes GPS gets the satellites in 30 seconds sometimes no satellite after 15 minutes. This of course in the same location...
This is really anoying, any other ideas ?
PS: I am using the french version!

Maybe that's why ... sorry couldn't help it...
Are you sure there aren't any other factors involved (like heavy cloud cover, rain, , etc.?) or more than 3 days since last fix (not that this should take 15 minutes - this is more than downloading the whole almanach). Can you check if you have signal all the time, or if you keep loosing all satellite signal? Because if it looses all satellites, he has to start from the beginning with the fix, so it's in a loop until he gets proper signal.

Well there seem to be quite a few issues with the GPS,personally i'm using the Destinator 6 software ,and here is what i noticed ;
With the official HTC rom :
The software detects the GPS in about a minute and acquires a fix in about 3-4 minutes with the GSM on and a clear sky.
If i softreset the device then 1/3 times it won't find a GPS antenna and i have to manually reconnect and define the com port,it then takes apprx 5 minutes to get a fix.
The weird thing is that when i used Destinator PN i didn't have any of these issues .
Lately i've started using img-32424-mUn and i've noticed a definite improvement in both GPS strength and speed.

i did use following test rom, the gps response is around 1min.
RUU_Trinity_CHT_1.23.751.1_101_6275_1.29.00.11_108_Test.exe
however, by using offical rom whatever config the baud rate or GDP, required 8-10 to get the fix.

the problem is that it's not stable
one day i get a FIX within 1 min, next day after 20...
and 2 days later, not getting any FIX.
i tryed with GSM and 3g ...
i guess the radio (or the GPS part) isn't as we excpect it
sad that HTC dont want to support users that NOT use TomTom.

I think it would be useful if each of us told the others the type of GPS software they were using as it (The GPS software)seems to affect the time it takes to acquire a signal.
Also try using the GPS with and without the radio (Flight mode) and see if it makes a difference.

No GPS Signal & Icon
Hi! I've another problem. I've downloaded new ROM upgrade and Tomtom applications. After waiting for 10 minutes, my device says no signal received. I read from some forums we can adjust some variables but there is no GPS icon under settings\connections folder.
Can anybody help me! I have version WWE 1.23.405.

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
Alonso

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.

My diamond GPS does not work

Hello,
I am trying since yesterday to make my GPS working, with no success. Everytime, I got the following message:
Cannot find port com. I do not know what the problem might be. I tried all Ports (from COM 0 to COM 12, and all Baud rates). Tried 3 differents GPS applications. Memory Map tells me for Port 0 GPS communication timeout...
In addition, I tried to play with the External GPS. I tried with Manage GPS automatically on and off. Still the same..
I begin to think my GPS unit is defective...
Any ideas would be appreciate.
Thanks very much in advance,
Philippe

did you change settings in the gps control panel?
the default settings can be left alone. COM4. Baud rate should be automatically handled and unless you enabled AGPS any baud rate will do, if you enabled AGPS then I think you have to use 2400 as your Baud.

I just noticed the GPS harddware port in setting, system External GPS is not saved when you click ente.
Exemple I choose COM4, and Baud rate: 4800. I click OK. When I reclick exernal GPS, Hardware, I have got ''none for GPS hardware port. I do not know if it might be one of the reason why the GPS does not work.
Note: I just flashed the new rom: 1.35.401.3 WWE. Might it be a bug in this ROM (just question?)
Philippe

I can cofirm TomTom working with COM4 and baud 57600. Signal pickup can be time hungry, tho. Sometimes I get a fix in 20 seconds, sometimes it takes as much as 10 minutes.

no problem using mapking...

Hello,
And thanks everybody for your help. I just updated to the new Elite 1 ROM, and now it works like a charm....Very good...
I do not know if there is many francophones on this forum, but there is a new french forum about the Diamond:
http://htc-touch-diamond.forumactif.info/index.htm
Not very busy yet, but....
Cheers,
Philippe

Same problem... The tomtom 6 don't detect my integrated gps... if i chose the wired and put ports like say before, it don't work too.. Any way for detect integrated gps?

Here are exactly my setting:
Setting system External GPS:
GPS program port: COM 4
GPS hardware port: None
Baud rate: 4800
Manage GPS automatically is checked.
So open your GPS program, choose COM Port 4, and baud rate: 4800.
Should work. If not, flashthe new Elite ROM. It could help too.
Philippe

I can't flash the rom, it will make the warranty expire... And the mobile isn't mine, it's destined to be selled, i work on a gsm shop...

got exactly opposite problem - when I leave these default settings in "External GPS" CPL, the Diamond will suck my batterry within several hours, as if the GPS was still ON. have found out that if I disable all settings in this CPL, it stops sucking power (but then I can't use the GPS, obviously) - any clues or solutions?

I HAD to enable Windows Mobile manages automatic in External GPS in 'settings'. Check if it is enabled.
Disabling it made GPS never work.
Strange?

Yes, unless I restored all settings to their original values (Virtual port - COM4, HW port - None, Managed access - checked), I was not able to use the GPS. But these were exactly the settings I was having the battery drain issue with... I miss the GPS LED indication vastly...

I am have this problerm too...
Solution : make hard reset.. no more!
And all will be ok ... about GPS.

i have same proplem
i have same proplem when i updat to the new rom 1.93

I have a similar Problem.
I Updates my ROM to the new branded one from O2-Germany and since then my GPS is not working anymore. in GPSMapware I get device.exe errors and TomTom7 keeps searching and searching and so on...
The old O2 ROM has no GPS problems and every software got a loc in about 10 - 20 seconds.
But the most intresting point is that my brother has a Diamond too and no GPS problems at all.
I think I will get a new one from O2 before flashing it and loose my warrenty

Telus CDMA Diamond
I've got problem too. First Diamond I had no problem with GPS, something happened with the phone I had to exchange, and new one (phone) GPS wouldn't pickup Sat. I'm on Telus CDMA. Maybe they removed physically on the second batch of Diamonds.

My GPS doesn't work too well either. I can usually get a fix eventually when outside with a clear view of the sky but in the car it is hopeless. I use TT7 and the GPS status screen shows that the Diamond can see maybe half a dozen satellites or so but with very low signal strength. The bars stay grey for ages and then eventually three or four will turn blue and all the time the battery is draining like crazy. I also have a Holux GPSlim 256 and with that I get a fix much faster and the signal strength is much higher. I can also use it in the car with no problem.
I have to say I'm pretty disappointed with the GPS performance of the Diamond and from the number of posts in this forum from people with similar problems I would suggest that there is a design flaw or very poor quality control. I had an XDA Orbit 2 for a while and that was far superior.

Me too
my diamond have the same problem too.
it was working with the old rom's and the early new
but later with new rom's it is locked, I don't know why or how to fix it.
then I back to the last good one but still locked.
it seem's working fine, because the software is detect the gps device and also detect it on port 4 and baud speed, but without signal any more.
I used Garmin, Destenator, iGo, fanaeen, and gps test.
and I try to use all avaliable solutions
I used all diamond rom's here and used all radio version's even the hardspl I changed it too with no succeed.
any advice would be help!
thanks in advanced

Hi,
I own two diamonds and I also found problems with the GPS in both of them. Probably mine is not the same you are describing. What I get is the following:
Running TT7, the GPS works but TT7 map in the screen remains in grey color. Rarely it shows color for some seconds and l"oses signal" again. It navigates, but no messages on proximity of POIs work. Also, when driving, if TT7 is forced to recalculate (every time I do not follow the instructions), it forgets about the required destination. In the GPS configuration option within TT7 it does not show satellites, the bars are empty and the coordinates shown are grey... but showing values!
Finally, I found the reason. I use Bluefire VPN, a piece of software to connect securely to my company. The GPS and Bluefire cannot live together.
I have tried everything: TomTom 6, changing COM port (many combinations)for the GPS, A-GPS on and off... No way.
It worked perfectly in P3600. I tried many ROMS and pieces of software without problems but in the Diamond I haven't been able.
Perhaps the reason is some resident code of Bluefire. Don't know. In any case, if this is a case similar to any of you, my advice is the following:
Hard reset, install TT7 and maps and test the GPS. If it works, start installing software until it crashes.
In my case, the GPS is always dead after the soft reset required after the installation of Bluefire, and it works again after another soft reset once Bluefire is uninstalled.
Hope it helps and hope somebody can also help me solve this issue.

SOLVED
Hi guys
Here is my solution.
First you have to flash 1.13.25.24 radio rom sometimes it can be solve the problem.If not you must open your phone with Htc service manual and find gps coaxial cable and check it.Sometimes it can be pulled out.Mine antenna was unconnected and gps couldnot find any satellites.Sorry for my bad english.

GPS can not find satellites

Hi.to everybody in this forum.I have an HTC Diamond previously locked to Orange Uk now unlocked to all networks ....with your help.
But I face a great problem!!
GPS is not locating satellites at all!!!
Before you ask me if I have read through out the forum, YES I DID (A LOT).
I tried everything, HTC GPS tool , GPS TEST , hard resets ,soft resets ,mpla mpla .....everything...but no result.
CAN you help??PLSSSS
My Htc comes with the new ROm 1.93

you didn't get a fix from the beginning or was it already working once?
what app are u using?
the gps i configured correctly?
app sees the GPS module?
start in this way, then we can talk...

I had same problem ,after my provider update (the radio maybe) it solve the problem. check what is your radio version and tell us..

I hope i dont have to get involved into this since the phone was bought from ebay (UK) and I leave in Greece!!.Now phone is unlocked and I think I will not be able to contact Orange network for update.

I don't know what I had b4, but now mine is:
ROM:1.93.456.2 WWE
RADIO:1.00.25.05
Seems like your ROM version is kinda old,
Maybe one of the guru here can help you,
or update your ROM by yourself (your own risk)

com port 4, baud 57600, gps enables - this is what i use in iGO8 and works perfect
what is set in "setings->system->External GPS"? Here you can find some settings also
programs - com4
hardware - GPS HWport none , baude 4800
access - tick manage GPS automatically

I lost gps functionality after flashing to a new ROM.
Radio .07 and doing a "warm start" in htc gps tools got it working again, now from cold (ie initialising device to getting lock) is 25 seconds. (20 seconds to initialize gps, 5 seconds to get a lock!)

Try using gps gate,it will automatically configure gps settings and then start destinator,it should detect the inbuilt gps receiver and give you a fix,I had exactly the same problem with destinator 7, it just would not detect gps after using gps gate everythings fine,hope this helps.

Any help plssss????

Changed the radio but still the same .It will not find any satellites.Maybe the gps chipset is %^$%$#.

ok, your GPS module is detcted, right?
In GPS test, can you see signal of satelites or not?

Flash your radio again and do intermediate hard reset before phone fully boots. If doesn't work flash both rom and radio (hard reset after each!). Just had the same problem on my diamond (solved today) and had it in the past on Kaiser. GPS detected, gps tool see sats but they are permanently red and flat (like they wouldn't have any strengh at all) And its always to do with radio so don't worry about your chipset.

I just read another thread and found this:

Hi,
After i had some GPS-Problems (no Sattelite link etc.) i tested many combinations on my own. At the End this works on two Diamonds:
1. Follow the "Unlock description" if necessary
2. Flash your ROM (i used the AZTOR V6)
3. Hard-Reset your Device! <- Important
4. check Com-Port
5. Cold Boot yor GPS
6. Warm Boot yor GPS
7. Hot Boot your GPS
8. No link-Problems, no Lags and very fast Sattelite link (after a few Tests: First Sattelite Link ca. 2 min. After first using GPS ca. 20 sec. to Sattelite-Link)

Diamond GPS doesn't fix satellites

hi, i have installed TomTOm7 and Sygic Traffic GPS together on my Diamond and now the device doesn't fix satellites...the settings for external GPS are: COM4 port, baud 4800 (default settings) and the softwares are setted correctly.
What do you advise me to check?
thank you

Try GWatch .5
Getting a fix on a satellite is a problem with the Diamond and Pro. I had this issue with TomTom 7 too with radio v1.02.25.28. I installed GWatch .5 (app found in this forum). Start it and go to GPS (1st button) then to settings. Select COM4: and baudrate 9600 and NMEA then select Activate GPS on the same screen. Select the Check and wait for Valid satellite to appear. On locked, minimize and start TomTom7. Go to GPS setting and select Other NMEA GPS then baudrate 9600 on COM4:
Hope this helps.

i'll surely try this issue...but i think it's a little bit complex way...but if you say that this problem is known for Diamond and Pro..hope there will be changes with new roms and radios!

did you recently upgrade your radio rom?
if so try a gps cold start using HTC GPSTool.

strange thing happened...i just installed GWatch .5 and tried to make it fix satellites...it gets to 8 valid satellites but doesn't fix!I turned off GWatch and restarted TomTom, and in quite a minute he got satellites fixed...after cold fix then only few seconds to fix again satellites...very very strange!Yesterday i spent more than an hour trying to make that s*** fix satellites!
I haven't upgraded radio since I installed 25.05 few months ago...i just had an hard reset 5 days ago.
What exactly is HTC GPSTool?
Thank you

i forgot...i have A-Gps disabled with Diamond Tweak 0.5.3 and in some case i start No-Data to block internet connections just before starting TomTom!

even i have issues the first time i try to get a fix after hard resets. Once i do, its fairly quick

i upgraded hardSPL, made hard reset of course..upgraded infos in quickgps...the fix is now immediate...hope everything goes so well!
