Garmin XT 5.0.20w loosing GPS fix and more....

OK Guys I was searching this forum and not only this but could not find any answer or tip to my problem, so as far as i do not like to start new thread here we go....
It is a bit weird as it started to happen recently...my Garmin XT working ideally with TOPO maps when u hiking but as soon as i get into a car and connect my HD to power and try to navigate home it starts to loosing the plot... basically it will find the route and start navigating and then suddenly loosing GPS fix and switch screen off sometimes, and even once or twice unload itself so phone went back to main screen. also once it lost fix i can see that Garmin switching between full screen and full window view...as i can see top bar every now and then.
contacting Garmin is a waste of time....as they did not offer any solution except hard resetting the device, and i wont do that, to much work to put back everything together and not enough time.
if anyone have a clue what it might be please share ur thought, and give me a tip to sort this out.
I'm using non modified HD with standard WWE version on Orange UK.
Thanks for any help
PS. For MOD, do not know if I posted in right place so if need to be moved, just move it.

Oh and I thought my Garmin was going crazy ! Actually Sygic is working fine with me except that I get some lags sometimes but it is all fine. But yeah tell me about it ... I tried Garmin and it looked for me better with much more POIS than Sygic but few days ago I was driving and suddenly the software started to go into other direction, like it was tracking something else. I think it is a bug with the software maybe. Thank God I am not the only one aware of many things going on with my HD

have u ppl tried 1.13.25.24 radio rom??
with this update... getting fix is very fast (basically it does not search for com ports, shows u connected when u start GMXT).
only drawback is that u can not see the satellite bars in info section.
used gps for short distances (@ 140kmph not much lagging and no disconnection). maybe i'll go for a long drive this weekend... then i'll know if there is a problem of disconnection or lagging etc.

With TomTom i get the same problem, however i don't know what the problem may be because A-GPS is turned off, but it has happened twice where it would take 4 times as longer to find the signal, and whenever it did it would go find then lost.
Soft Resetting fixed it up however i did notice my QuickGPS was not up to date anymore, must have went out of date the day before and possible cause for it acting up.
Try updating QuickGPS, might fix it up and be sure to have A-GPS off.

still no solution

i did forgot to mention that my A-GPS is already switched off. the problem is that Garmin keep switching between full screen and full window view and i suspect that my be the bottom of losing fix in the car... i want to stress out that while walking & hiking i have no such problem..... ONLY IN THE CAR and that is most frustrating.
and changing radio....well i'm not convinced as this could halt my phone if something go wrong and i cannot let it happen, as it's not only a toy but business tool, so i rather dont play with it.
any solution????

Changing radio won't halt your device. As long as you have Hardspl on your phone beforehand you'll be fine!

And pelase report back if it does solve your problem

Is this a solution????
Hi there, I see we lost some posts over here....so again latest update...
On the way to work this morning I tried garmin with Intermediate Driver and it worked!! but....there always has to be some but....I saw increase in lag...also i did it a bit different way then usually as I did not connected HD to power... will test it again with power connection tomorrow.

i have extensively tested gps of touch hd while driving from 0 to 120 km in open highway
i never lost the fix
it kept locked to satelites but major problem was battery drain
so i have to disconnect gps latter on
i belive with gps on and satelite fixed driving around 80 to 100 km battery with die with in 2 hours .
otherwise there is lag of 5 to 7 km/hr in speed calculated via gps and its normal
my SiRF III CHIP based cowon q5 gps also shows 5 to 10 km /hr differance from actual speed of car
its normal i belive

laggy but working

from what i experienced earlier with garmin i can say that lag become much bigger...now when i'm past the junction, on the map i suppose to be either on or even before the junction... never had that before so i suspect that intermediate driver might be responsible for that. also i can say that when using tomtom i have no such experience.
wanted to ditch tomtom but with such a laggy response i will have to use both... garmin for off road navigation and tomtom for car navigation.
the only thing i can confirm is that using intermediate driver solved switching between full screen and full window problem as well as loosing gps fix... at least for me. but u get bigger lag instead....

HD2 overheating, not charging and rebooting - temperature monitoring

During the last week I experienced some strange behaviour on my HD2. I want to point out that in general I am very happy with it, but now I wonder whether my device is faulty or weather this is a feature.
What I have seen:
- my device had some sudden reboots when using it in my car, charging with car charger
- this happens only when outside temeperature is close to 30 degrees C or above
- it happens after some time (10 - 15 min) using Navigon or even just doing Bluetooth calls
- it usually stops charging the device, the LED is then blinking green & orange, then reboot
- I recognize that the device is very hot
- after cooling down it has lost the power settings
I found two other threads dealings with similiar effects
http://forum.xda-developers.com/showthread.php?t=707477
http://forum.xda-developers.com/showthread.php?t=627884
and now want to do some detailed anaylsis here. I installed BattClock (great tool!)
http://forum.xda-developers.com/showthread.php?t=612083
to monitor the battery temparatur and found the following:
- idle phone (office, not charging, 3G connect, push mail activated): 25 - 30°C
- phone in use (office, not charging, checking mails etc): 30 - 34°
- idle charging (as idle phone, plus charging): 30 - 34°
- phone in use, charging in car, summer temp 28°): temperuture rises up to 47°
The last case ended with a reboot, when coming up again the temperature was 47.1 degrees, green / orange was bblinking and charging has stopped. Before crashing the temperature raised from 33 to 47° within 15 minutes.
Can anybody confirm whether he can run the HD2 wíth 47° and above? I would like to understand whether I shoul return my phone under warranty or whether this is a feature. 47° is high - though I do not think too high??? I also got the impression that this issue is coming up more and more frequently with my phone and as the summer just has started this could mean I need to stop charging while driving. How to use navigation?
Any comments or ideas?
Regards Hase

Well Hase,
I've seen this a few times in the past when driving running CoPilot, Bluetooth, screen bright and charging.
In the last week, with a new ROM base and significantly warmer weather, I've seen this with just having the phone in the car charging.
Very interested (and actively hunting) a manual underclock to see if it helps.

I don't think this is a defect, but it does happen.
I've noticed it too a alot during the NE heatwave in the US.
I'm waiting it out for now.
47C is not too hot though, although maybe there could be some kind of feature with the processor?

Yeah I've noticed it too. I was driving in my car running Bing Navigation with no problems for about 2 hours with the windows up and the ac on in my car. 10 minutes after I opened the windows when it was 101 F outside bing maps would randomly shut down and other apps would not even open. Closed the windows cranked the ac and held my phone in front of the vent to cool down and it went back to normal without even having to soft reset. Seems like a feature to prevent damage to the phone.

I would guess its some overheat protection feature with the processor, as its really the latest, which means sometimes it may get too hot ( you know, 1GHZ is really fast and thus may generate much more hrest than normal slower processors ) . Just like Intel's processors, which also shut off when the temperature rises over a certain programmed known "safe" temperature and reboots the computer, in hope that when its started again, it would be cooler. As for battery temperature, the cpu may be even hotter than the battery's temperature and thus it may seem that the phone shut off at a low temperature, but in actual, the processor is REALLY hot. And as its a mobile processor and its known that the second hottest factor is charging/discharging the battery, charging may be temporarily disabled until it cools down to a "safe" temperature to prevent overheating/buring out other components. But that's just what I think. Best to check with Qualcomm or HTC if possible as it may also be a defect in the phone. Hope this helps.

I haven't experienced any reboots but I have had problems with my HD2 locking up due to excessive heat.
Leaving it in direct sunlight means I'm unable to unlock the phone due to the lack of response from the screen.
Yesterday my HD2 was charging in its cradle and wi-fi was on. The device got hot and became unresponsive and I ended up putting it in the fridge for 10 mins which brought it back to life.
The HD2 definitely has an issue with high temps, the screen in particular.

Have you tried LeoCpuSpeed?

I have had this problam as well. It also happened with my Touch Pro 2 when in the car, sun, Copilot, etc...
My fix was kind of a lucky guess. I have AC vents that blow on the windows of the doors when it is on the defrost setting. I just have the windshield mount sitting kind of over the vent for the drivers window. It is not quite in a direct line with the window, but enough AC comes out of it to get to the device and cool it.
When I do this, it goes from a rather toasty to the touch to rather cold actually. Even with the rubber "case" on it it keeps it down to a reasonable temp, if not below, with it charging, GPS going, bluetooth stereo and WMP all going.
Since popping it into the airflow it has not even gotten warm let alone started the warning flashes and such.
Kind of an obvious one, but those are the most often overlooked so I figured I would add it in.

In fact that was my solution too. I changed my cradle using one putting the HD2 in front of an AC outlet and now everything is fine. Just make sure the lower part of the HD2 where the USB cable is connected is not covered by the cradle or any cover as this is the place where the cold wind has to blow. Battery temp remains well below 30° C, if driving longer distances even below 20°. I am not sure whether I will get too low? And I do not now yet what will happen in winter when we get it freezing cold and heating will step in.

Does anybody have tried underclocking yet? Would be good to now whether this could be an option too. Sometimes even using the HD2 on hot days (without charging!) gets the temp up to 38° C plus. Best thing is not to hold it on the lower part.
I am wondering that still only some people get this problems. Either everybody is ACed (not poss in my convertable) or the problem is only with some HD2 or some ROM. Has anybody noticed any other strange behaviour after an overheating occured? I noticed some issues during the last months which I could not yet connect to any other reason. I am not sure whether I have had overheating bevor these occured the first time:
- all of a sudden bluetooth connex to my car was not poss any more
- all of a sudden pocket xls application and the note application got very very slow
- all of a sudden POP connect to google Mail did not show any mails any more.
These effects did not show up the first time all together, they came one after another, one per month since March. And probably I have had overheating earlier without even noticing it
Regards Hase

Hi, i have the same problem with overheating ... it stop charging when Battery Temperature reach 45°C. Battery PINS are all OK and clean
First : My Leo has Radio 2.11 (2.12 same problem)
OEM 2.10 (My own ROM)
Today Test : Go back to original ROM 1.66 (Radio 2.06) and my HD2 does not overheat ! Strange
I can see with PowerGuard that the charging current slow down when the temperature go up and reach max 42.3°C
Tomorrow Test : Radio 2.06 and my ROM with OEM 2.10 ... if do not overheat then i try with Radio 2.08 (more RAM ... TMOUS) ....
to be continued ...

Today Test with Original Firmware 1.66 and Radio 2.06 has problem too
Ordered new original Battery from Brack.ch ... when battery comes make new test to see if it's the battery or HD2.
Strange is that the battery is not so hot but the charge circuit of the HD2 is very Hot. (Hottest place is between SD CARD and SIM Card)

Hello,
I experienced the same sudden shut downs (not reboots) during the last days as well ("hopefully" only due to the very hot weather). And none of my POP3 account seem to work right now!
The internet connectivity seems to be okay, and of course I haven't changes any mail settings... but I cannot receive or send any mails. I get no error message when I try to receive mails but when I click on the new mail button my HD2 asks me to set up a new mail connection!
Any solution found to this problem?
Kind Regards,
DW!

On my side the problem is a bit different. POP3 seems to work fine (also no errors) but does not receive mails. Sending is o.k. And this problem is only with gmail, other accounts work like before.

PXL is Microsoft Excel on Windows Mobile. On my HD2 it takes about 2 minutes now until it open either the list of xls files or a dedicated xls.

Yes I did, but with the same result, does not receive emails...

I had my HD2 heat up to about 48degs when in use while charging it. No problems encountered. Perhaps its defective. Send to HTC for repair?

Hmmm, that's no problem on my HD2 - Mobile Excel is opening as fast as ever...

I have now deleted 2 of my 4 mail accounts and re-installed them; the other 2 I simply have re-installed withour prior erasure - and this seem to do the job! Indeed I have done this more than once now, but 3 accounts now already received test mails... the 4th is a freemail account which I can only use every 15min. via POP3/IMAP...

But what was the outside temperature? I think the overheating has to do mainly with using the phone (gps) while charging in a hot environment inside of a car.
Just charging the phone shouldn't use the processor to any significant point.
Just my $.02.

I could not believe it what I read here, but now the high temperatures in Austria caused the same problems on my HD2 when navigating in my car. HD2 after 2-5 minutes blinks orange-green (no loading) and after maximum 10-15 minutes crashes.
Unfortunately I have to rely on navi-function for my upcoming vacation. No solution to place the HD2 in AC-stream in my car with this stupid original HTC-Car-Navi-Holder.
When driving in the heat of noon I don´t even have to switch it on, just mounting into the loading-cradle is enough to make the HD2 crash after 10-15 minutes, only 3G on, nothing else (no BT, WiFi, HSPA, no app running etc.)
Until now I was quite satisfied with the HD2, had no crashes or malfunctions so far, but now I am really fed up with this piece of sh.. and I don´t think there will be a hardware or software-solution (except swichting it off) since the HD2 is malconstructed.
This was the last time I bought a HTC product ............... Crap at a high price I can have with an iPhone too ................

GPS Issues on Desire HD - Considerations, tools and tips

I'd like to make a unique single thread with all the issues related to gps on DHD and the procedures/tips to make it work better.
MY EXPERIENCE
I was ready to go to dinner to my girlfriend's uncle (50km far away). I bought my DHD two days before. Ok, let's try gps. Google navigator. Started driving and my phone didn't get a lock. After five minutes of driving, i needed some help from navigator. Nope, still no gps lock. I stopped the car, got out with DHD in hand and lock again in two minutes with the sky in sight. No problem until destination. At the end of the dinner, on the road again. For the first 3 minutes, gps lock. Then lock lost, gps icon blinking and nothing. Tried to reload the phone. Fast boot first time and complete reboot the second time. I didn't stop the car this time, tried while driving (my girlfriend handled telephone while i was driving ).
It took 45 minutes to get lock again. Thanks god, i learned the route on the journey there.
The same thing happened again three times in the next days.
I thought that some software installed corrupted my phone.....(sorry, i was used to the windows mobile whims!!!!).
Hard resetted, but the problem was always there. Without logic, sometimes i had gps lock, sometimes not. Sometimes my DHD was keeping the lock until destination, other times gps lock was lost while moving.
GENERAL CONSIDERATIONS
Not all the people complaints about gps on DHD. I don't know why but there are many people who have problems using it. I think that, except for the faulty devices with defective gps chip, the behaviour is the same for all devices. Only the people perception about the performances of gps are different, and their behaviours of use. I had different expectations about gps. I was used to start driving without gps lock, my HtcHD would have always found lock in one minute anyway. Even if moving, even if many clouds or raining.
People who arrived to Android coming from Windows Mobile do experience a general lack of speed in locking gps position and a very different way about gps is handled by the OS.
My DesireHD hardly locks gps where my previous HtcHD locked gps in few seconds.
The same difficulties I have now with DesireHD, I had them too when I installed Android on my HtcHD. But I thought it was the unstable Android SD ROM's fault.
Another issue is the speed of hot start: DHD seem to have a very very short term memory in fact of gps. Hot start is really hot only if you reconnect within short time.
My HtcHD was able to reconnect in few seconds even if hours passed from the previous lock, if not moved.
My new DHD needs more time to lock, even if the previous lock was 30 minutes before. It happens to take 45 seconds or more to lock again if the sky is not completely in sight.
Even if I get lock with GPS Status, shutdown the program and I reopen it few seconds after, gps lock is not immediate. It takes almost ten seconds to lock.
I think I have to forget the Winmo performances in fact of gps, on Android.
(I think it's the only thing i'm gonna be missing, anyway......)
I think i'll have to wait for the lock before start driving from now.
ISSUES EXPERIENCED BY USERS
- DHD locks gps but when moving it loses the lock and it stays for minutes (from 10 to 60) looking for it again. -
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock. Phone never ever locked gps, whether indoor or outdoor, with the whole sky in sight.
Try resetting AGPS data and let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
If you never ever succeed to get a lock, you should consider to have a faulty chip on your device. I think it's better to contact HTC Repair service.
- DHD behaves with no logic. Sometimes it finds a lock in seconds, sometimes it takes ages to find a lock.
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock if any data connection is available.
Try resetting AGPS data e let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
TIPS
Do all of these steps. And, except for the first, try to do them all the times you use gps. And evaluate the improvements, if there are.
One time procedure:
- Force the phone to lock gps without any data connection and check APN type (see below for the link to step-by-step procedure).
It is important to put the phone outdoor on a stable and straight surface in order to get a strong lock, with a complete view of the sky.
My advice is to empty a-gps data BEFORE doing this operation (this can be done with GPS Status - Menu => Tools => MAnage Agps state => Empty data - The program is free and doesn't need root permissions)
Before every use of gps:
- Use FasterFix (needs root permissions) to change NTP server zone. The system/etc/gps.conf file contains parameters for NTP server and AGPS data. In mine i find that the ntp server used is located in northamerica. I live in Rome so I use Fasterfix to change it, forcing to use european ntp server. I don't know why but Android changes by itself this file, putting again north america server, so i have to change it more than once in a day to keep it using european server.
NOTE: Fasterfix gives back an error the first time you open it, choose the seerver and try to apply it. Only the second or the third attempt, it returns an ok result. Don't mind error. Don't worry about it. Even if returned error, it did its job anyway.
- Synch Device clock with atomic time. I use ClockSynch (needs root permissions), but every program capable of doing the same thing can be used. This is intended to help device in calculating your position. More accurate time means less corrections by the software, faster position calculating and a more accurate position.
- Let the phone get a strong lock BEFORE starting to move with your car. A couple of minutes before, you should let your phone on a stable surface, with sky in sight. Outdoor, obviously. Better if outside the car.
This thing could seem stupid, i know. But let your DHD get the lock in a place where it has a good view to the satellites. Let it acquire precision (you can see it in the left middle part of the screen, using GPS Status). Start moving only when precision has reached a minimum value (expressed in meters/feets - lower value, more accurate). You will see that gps lock will be more and more stable than before.
- Use a task killer program to kill all the processes which may use gps. I noticed that if one or more program able to use gps have been left opened in background, sometimes, without logic, something goes wrong and Gps receiver is no longer reachable by software.
In this situation if I open GPS Status, I see gps icon blinking, but in fact no satellites are seen by the program. I mean that on the screen is not shown 0/3 or 0/5 satellites. On the screen i see nothing about the number of sats, neither 0/0, empty. And in some situations this thing cannot be true (i.e. if i am completely outdoor with a perfect sky view).

Just 1 possible solution for you, have you tried to upgrade your radio? This may sometimes help solve GPS problems.
Sent from my Desire HD using XDA App

No, I didn't upgrade my radio.
I'd like to do it but i'm very hesitant to mess around with my phone like this.
P.S. Let me know if you had some improvements.

Updated radio can make a MASSIVE difference. One of the best things you can do to your phone if you're having any kind of GPS / 3G / Wifi issues.
Go to:
Menu > Settings > About Phone > Software Info
Where it says Baseband Version, this is your radio version.

For me the most annoything that happens with GPS is that when playing a music and using at the same time an offline map gps program, when a voice or some ding dong sound happens, the music played stops and resumes after those gps sounds ends...
I think this is due to Android sys... even WinMobile it's better on this...

Thanks for the tips. My GPS is locking on very quickly now and even inside buildings. I used clocksync + GPS status + Fasterfix. Fixing to around 8 - 9 satellites indoors and 12/12 outdoors.

Done.
Great.
It Works!!!!
initially it would take me a good minute or two to acquire a precise location INDOORS, now it does it in 10-15 secs!!!!!!
i was already using GPS Status, this is with FasterFix.
Thanks.

so strange I never had problem with GPS, always fixes in less than 10 second and never loses as well.
I use iGO and it never let me down.

I had problem with gps-lock from the beginning.
Tried the link above "gps-lock without dataconnection"
Now it locks within seconds
Sent from my Desire HD using XDA App

Personally, I've had no problem with gps for apps such as Google navigation where the screen stays on.
It's a different story, however, for apps like cardio trainer where the phone loses gps lock when the screen is off. I understand this is a known issue with Android 2.2 and has been fixed for 2.3+. I don't know if anyone else has problems with this.

but mine desire didnt work? first when take out the sim card ,reset and download data ..it work like charm..lock around 10 sec..then put sim card back it took age cant find satelite to lock..
anyone know what wrong?

On my DHD, indoors, GPS sucks badly.. apps such as "aroundme" its pretty useless, just hangs finding a signal. but outdoors when I use navigation, etc it works okay. I dont use GPS that much anyway, so cant complain. It is a tad annoying when your indoors and cant find stuff though.

I've had really big problems with my GPS.
Could not get a lock so I rooted my phone and upgraded the radio. Changed the gps.conf file and reset A-GPS settings and tried GPS without a dataconnection. None of the suggested things above did work, so I downgraded the radio to stock and unrooted my phone and sent it to a repair center.
Hopefully they will fix it.
I have a Hero (root) and a Desire (stock) and they get a lock on within seconds and works flawless even indoors.
I guess HTC has a lot of faulty GPS modules in their Desire HD mobiles, but not all are using GPS so therefore we only hear about some of the problems.

Trying the Nexus one fix as in the first post, after taking SIM out, I do not get any GPS signals on GPS Status, if I put SIM back in I get fixes but GPS unusable as it keeps losing connection whilst in journey. The steps I have taken so far are as follows:
* Take your SIM out of the Nexus One
* Power on the device
* Turn WiFi on
* Turn GPS on
* Open application: GPS Status (ver 3.4)
* Go into its Settings menu
* Click on GPS and Sensors
* Click Manage A-GPS state
* Click Reset
* Click Manage A-GPS state again
* Click Download [You'll see a message telling you that a data connection is needed, ignore it]
* Now put your phone on a stable, straight surface in order to enable the phone to get a lock, within GPS Status. This time, you’ll see your phone get the lock way faster than before.
Any help will be appreciated.

There's some developments about this issue...
Or one use the nice HTC Gps Software (at least the version that cames with gingerbread) or use the iGO Amigo.
I tried the iGO Amigo and I finally can listen to music at same time when the voice from iGo speaks!!! There's no interruptions at all like on the majority of GPS softwares that I tried on my DHD (don't know how it works on another devices)
I think that this issue is something that is only developers fault cause initially I thought it was due android design, maybe it was only possible to play something only from one app at a time. (ie. not play two things from two different apps simultaneous) but I figure that after all that is possible.
Bad developers!!!!

GPS Problems: finally the solution
Hi all,
Here I want to tell my experience with HD Desire GPS to help all those who were (like me) desperate.
The way to solve exists ! Read to the end to know how.
I bought my HD Desire in January 2011 (from Euronics in Rome - Italy) and after one week of use the problems began with the GPS.
It did not fix more ... but above all there were more than 1 or 2 visible satellites ... even in open sky, in good conditions, even outside for 30 minutes.
The phone was obviously still immaculate (without root and with the original ROM and RADIO) then I went back to the shop where I bought ... and using GPS-Status the seller has found that actually did not work.
Very kindly he changed my on the flight the phone ... I installed GPS-Status on the new phone just replaced and now everything works fine (fix in less than 10sec and 7 / 8 satellites visible).
I came at home and for 2/3 days it worked wonders but soon it began again with the same GPS problems.
No more fix and at maximum 2/3 satellites visible.
Building on the fact that the phone had been replaced and ... GPS Status actually had made a fix in less than 10 seconds ... (When I had replaced) ... I said, Sure ... is certainly a software problem and not an hardware one ... because the phone is a new one.
So I did a factory reset ... reset all settings as the original ... and retried. Nothing.
The GPS was dead for the second time in two weeks.
Then, I began a careful search on various forums (both Italian and international).
I've tried everything ... really everything ... but nothing. It does not work !
Tried GPS-Status (A-GPS Reset, Download), then fasterfix (it.pool.ntp.org) then I started to change ROM (root, S-Off and ENF S-Off), then I tried all possible Radio and RIL in all combinations. Sometimes happen that the fix was very fast and this gave me the illusion (temporary) of having finally found the solution. However, on time (sometimes even after a few minutes) the problem returns back!
I also tried to clean the contacts of the GPS as shown in this video on youTube(h**p:/*w*wdotyoutubedotcom/watch?v=7qm_z65LA8k).
At the end ... after 4 months of trying all... I sent back in warranty the phone to the HTC service (S-ON and leave to unroot because it was under warranty).
After 10 days of impatient waiting, HTC gave me back the phone and say that the GPS was faulty and had been replaced.
I redid a restore using Titanium Backup Pro ... restoring back all in the exact same conditions I had when the GPS was not working.
Now everything works wonderfully !!!
Im using the original ROM (RUU 2.36.405.8), original Radio (12.54.60.25U_26.09.04.11_M2) and the original Kernel (2.6.35.10-g0956377).
Fix in 10/20 sec (everytime), with at least 7 / 8 satellites (tested for several days now).
Moral of the story ... There are lots of HTC Desire HD phones (probably the first stock) that today are still in the form of stocks and inventories in some shopping malls / shops with the GPS module that is broken !!! (it works for a few days and then no longer works).
The only way is to send back your phone in warranty and ensure that GPS module is replaced (having first restored with all unroot and S-OFF as otherwise the warranty does not apply).
Believe me ... if you have tried everything ... this is the only way!
Now I'm an happy HTC Desire HD owner (with Gingerbread) with a GPS which is a splinter.
Im currently using Navigator, Google Maps, CoPilot and everything works great !
I hope this post may help and comfort those who are desperate and can not run the GPS on the Desire HD.
Greetings to all.
Andrea.

[Q] GPS freezes phone (w osmand,maverick)

Hello wise xda guys.
Any ideas why my hd2 freezes after some time, when I use gps with osmand or maverick (or a couple of other software I tried before and unistall). It freezes completely, and I have to remove the battery. While it is working (before freezing) everything works fine.
[Another symptom (maybe irelevant) is the very slow gps fix (the first time), which deosn't really bothers me (I'm a patient person). I'm just writing it here because maybe there is a relation]
I use: Froyo 2.2.1, mod: Cleandroid 2.55, MAGLDR 1.13.
Otherwise the telephone is more or less stable
thnx

Same issue it seems...
Going to re-flash WinMo and test there.

I'm having the exact same issue lately and it is not funny/safe at all.
I first had it happening in google navigation all the time and now in iGO and Waze.
Can this be from Rafpigna's undervoltaged kernel or be a hardware issue?
Unfortunately the device freezes completely and doesn't give any error.
Does a log exist somewhere?
Any help is more than appreciated!

Yeap, still the same problem and I can't figure out why.
I've tried more than 10 different apps, but allways the same. After some time the phone freezes. I remove the battery, start the app and after a while, the same.
I tried working with battery only or with car charger only, still the same.
I removed and brought back all my apps with titanium backup, still the same.
I have a suspicion that when it stacks and after rebooting, if I leave it in peace (I mean don't do anything with the phone, just keep it without running any app), for some time (10-20 minutes), then it starts and keeps the gps app more time, than the time of the initial freezing. Maybe this is a symptom that could ring a bell to an experienced guy...
Anybody, any ideas?

I think mine is related to heat.
Left it in my pouch and placed iGO in demo on a long roadtrip. After 15 minutes the phone was warm and the screen was frozen so I had to get the batt out again.
More than frustrating since I have a 700km trip to do on Thursday.

Not sure about the heat
I had the same suspicion, that the heat was causing the freezing ) funny language ah?).
So I tested it while keeping it cool (I protect it from the sun and remove the car charger), but still the same happened. After some time it froze again. (the phone was cold)
I have a suspicion that a possible reason is the rendering of the maps. I've noticed that I have the problem, mainly when driving a car, where the maps images should change more often. I kept it in my pocket and made a few hours trekking, with no problems. Though in my pocket I had the app running in the background and I only open it a few times, just to add some points on the map.

There is also this thread, by Crash-nl, with the same subject (more or less) so we can combine powers.

I'm also having GPS freezing issues, but probably way worse than you guys. I just got my phone from service center, but the issue still exists. I just quote my comments from an another topic:
I've now got back my HD2 from the service center. The GPS is now working, but not in Android. When I was using WinMo 6.5 with WWE 3.14 and 2.15.50.14, the GPS worked great. Fast lock, TomTom worked well and Google Maps worked fine. Then I decided to get Android again and after I installed everything, I discovered, that I had the same exact issue like prior the repair. The GPS starts looking the signal, if it doesn't find it, nothing bad happens, but when it does find the signal, it causes the phone to freeze. Instantly after the signal is found, it causes instant freeze. Screen stays on, nothing happens. What can cause this? I haven't yet tampered with the gps.conf settings, but I don't even think that it could fix the issue. I'm really going crazy with this.
Yeah, I'm thinking also its a driver issue. My current Android build is RAFDROID 4.0.2. And since this issue seems to be exatly the same, like before the repair, the GPS probably doesn't work in the earlier versions of RAFDROID. However something has changed in my phone, because the GPS has worked with nand Android builds in the past and even with RAFDROID 3.0. Now however, it doesn't matter which build I use, the issue always exists. Could it be caused because of the GPS module? I mean, does the WinMo 6.5 QuickGPS app save the AGPS data directly to the GPS module? So could there be some kind of corruption in the GPS module? I was having some sudden reboots, while using Google Maps and TomTom in the WinMo, but I was able to fix them, by hard resetting the device.
First time I started having this issue was, when I updated from RAFDROID 3.0 to 3.1. After that, the GPS has always caused instant freezing, when using GPS in the Android. Even downgrading back to 3.0, didn't solve the issue. Now I'm having this issue with all Android builds.
It's possible that my GPS module or "chip" could be somehow broken physically, but it's no point sending the device back for repair, because they send it back and say, "there's nothig wrong with the GPS". I'm really hoping it's not a hardware issue, because if it is, there's really nothing that can be done. I have still about a year left from the warranty and changing the module myself, will void the warranty. I just cannot understand why does the GPS still work in WinMo, but not in Android? Because if the module was somehow broken, should the GPS be defective also in WinMo?
I have tried flight mode, Wifi and 3G off etc. and the GPS DOES WORK. So the chip is not dead.

Just did some more testing on mine to try to find the issue.
I have always had a freez when I used google navigation with the sat image from the start in Android. But last week it happened in iGO and Waze which scared me a bit.
As a matter of test I installed WinMo again last night. Fantastic OS btw! and installed iGO.
Everything was up and running at 2am and I decided to let it do a demotrip of about a 1000km. The demo also sets the GPS receiver active.
I placed the HD2 it next to the fan of my laptop which is always on to generate some extra heat.
This morning at 10am the demo was still running perfectly.
Just reinstalled Android on it again. After 3km's in iGO 'gps signal lost' . I cannot get it back in any way. The GPS symbol is stuck in the bar above even if you disable GPS in the settings. So reboot is the only way.
This is getting very frustrating for me since my phone needs to work as GPS and may not fail.
Also a funny one is that it doesn't seem to matter on mine if the gps.conf file is on there or not ;-) lock time when the hd2 works is approx 1min

I'm having this same exact issue! However I just discovered that the local service center did not change the GPS module or antenna. So this might be the reason why my GPS doesn't work. The service center was fooled that the GPS works, because they didn't test the GPS thoroughly. YOU HAVE TO ENABLE FLIGHT MODE OR TAKE THE SIM CARD AWAY TO TEST THE GPS!. If you don't do this, you are being fooled believing, that your GPS is working, but it's not.
You guys should test your GPS, by going back to WinMo 6.5 and leave your sim card away from the phone. If your GPS can find the signal even without the sim card, congrats, your GPS is working. If you want to be double sure, enable flight mode and try again. If your GPS cannot find signal, your GPS module and/or antenna is broken and needs to be replaced.

Well my module is working.
Easy way to test it and no need to take out your sim or so.
Just use the cab file attached to this post. If you will start it the first time it will scan the ports so you can end up with a small error in regards to BT but it not a real error.
The tool will continue to com port 4 where the gps mod is active on.
Go stand outside and voila, mine starts to show bars like it should be.
I'm taking a different approach now.
Ckeared everything and also took a fully fresh formated sd-card .... (as I type now not working)

Thanks! You just saved my time a lot! I downloaded and installed that app and I was able to get a succesfull GPS connection and now I can even get GPS lock, when flight mode enabled or sim card removed. This was impossible before installing this app.
However it seems that we are both suffering from the same issue. GPS does not work for me in Android. It has worked in the past, but nowadays, it doesn't matter, which Android build I use, it either freezes the phone and only way to fix this, is by removing the battery or it doesn't find the signal at all. Sometimes the GPS stays on, even if I turn it off. The blinking GPS icon goes away only by restarting the device.

If you are using gps navigation software on sd card, try format micro sd card with FAT32 and DEFAULT ALLOCATION SIZE option, do not choose allocation size such as 32,64 or any other except DEFAULT.
Try it and GL.

Did anyone try this method? Looking at other threads I see people saying that only a warranty repair will fix the issue.

freezes
Hi. I had the same problem, i try everything formating sd, different builds and kernels. I disable "use wireless networks" and GPS work with no freeze.
Do you have a freezes on games?

did any one found the answer ?
is it a hardware problem ?
or a software ?

Thought I'd throw in that I'm having the same problem running hyperdroid rom on a telstra hd2. GPS finds a lock, works for about 2 mins then freezes requiring battery to be taken out to restart. I'm leaning away from a hardware issue as copilot worked perfectly on the same phone when I was running windows 6.5...

Just an update, after installing the new GPS fix from this link http://forum.xda-developers.com/showthread.php?t=1100114

Hi all,
I'm facing the same issue reported in post #12. I'm actually using latest Rafdroid HD (Froyo Sense) build on SD. Do you think I can try the fix in post 18, also if it is for Gingerbread builds? Please advise.
Thank you.

I sent my HD2 for repair, now got it back, but still have issues!

Hi,
I recently sent my HD2 for repair, because it had heat issues and GPS couldn't get a lock. Now I've got my HD2 back, but when I try to use the GPS, it either doesn't find signal at all or when I use for example Google Maps or TomTom, it causes the phone to reboot. I've used the QuickGPS software to get a faster lock, but this doesn't resolve the issue.
Also the heat issues still exist. Whenever I wan't to watch videos etc., the device heats up a lot and causes the phone to reboot. The bottom of the device gets always very hot.
The service center did change the touch screen, chassis and installed "HotFix-update", but these didn't solve anything. Does this mean, that the service center changed wrong parts? What actually can cause heat and GPS freezing/rebooting issues?
I'm now using stock WinMo 6.5 and the ROM version is WWE 3.14 and the radio version is 2.15.50.14.

Watching video or any activity that constantly uses the screen also uses a lot of battery power and it will get very warm/hot.
Have you tried any other software to test gps usage?
Do you have ALL the settings for Google/gps/locations and maps set up in the correct manner?
Do you have a case or any other protection on the phone - if so remove it
If your ambient temps are high this just compounds any issues with heat

first time to hear that
will be very carful

I was able to get the GPS working fine. However it doesn't work in Android. If I turn on the GPS and the GPS starts looking signal and when it founds it, it causes instant freeze. This is a real mystery to me. What can cause this issue? WinMo 6.5 with WWE 3.14 and 2.15.50.14, GPS works great, but when I switched to nand Android RAFDROID 4.0.2, the GPS doesn't work anymore. Or it does work, it does look for the signal and everything, but when it founds it, it causes instant freeze. Screen stays on, nothing happens.
I should point out, that I was having this same exact problem, prior the repair. And some time ago, I was still able to get the GPS working in various versions of nand Android. But now, whatever Android build I use, I have the same issue. Something in Android is messing the GPS module.
The heat is not that bad of a problem in Android, so I can live with that. I'm not using any bumpers or any other protection.

hi if you sent it back to htc repair center contact them again and say problem still there they should replace phone for you

Send it back for replacement. Yeah the phones become warmer under certain conditions but I use mine to watch hour long XviDs one after the other in the sun and I have no such issues. It takes constant downloading of data with GPS locked and loads of apps open for mine to warm up! Sounds like you need a mainboard replacement to be honest, surprised they didn't switch the boards the first time and test .
I've never had mine reboot or go crazy on me due to heat, at worse the battery temp check kicked in in WM while charging to switch off charge (flashing orange led) with my cheap Chinese battery
Sent from my Nexus One

I have heard that the high temperature causes by 3g... If you use 3g data, try to disable it and then try gps and movies again.
The conclusion, btw, is to sent the phone back for repair or replacement.

Same here my brother's hd2 working perfectly fine but mine every time temperature exceeds 33 celcius gps cause phone reboot and if i manage to turn gps on can't find fix

I got my phone up to ~42C while I was working in an auto garage and I still don't have reboot. If your phone reboots at a certain temperature, your phone is defective, and try to get it replaced by warranty, or you could try to modify your phone to fix the issue: http://forum.xda-developers.com/showthread.php?t=982454
