First good news:
Today, i have been "trial testing" the touch HD with Tomtom 7.415 in parallel with a tomtom ONE box in a car around Paris.
The voices have been in perfect sync (slight echo but NEVER above 0.2 s!) for 20 minutes!
Now, we could speculate and follow rumours, but this is a hard fact - relieving our beloved blackstone and TOMTOM by the GPS LAG accusation...unless anybody would claim that the tomtom ONE box also has the GPS LAG virus...
Second good news:
apparently, TOMTOM has just released new maps and tomtom7 explicitely for the touch pro and diamond, there is a large probability it will also work on the touch HD (see some "opinions" in this forum).
Notice that tomtom7 appears on the tomtom website if you identify yourself from Switzerland, Germany, Nederlands but is apparently not available for France and Italy. Maybe this is just a temporary situation due to translations and/or distribution terms.
So it's time for decisions, and i decided to buy tomtom7 - stopping "opinion forming" and "trial testing" evaluations. For once, my friends, there is a good company that listens to us and provide us with a great product....i have to admit that i feel embarassed!
.....Anybody could confirm that the official tomtom7 commercial release does work on the touch HD?
I nearly chocked on my grilled dumpling there....took tomtom 7 out for a spin and is fine on the HD

I completely agree, before your post I also posted the same stuff; there is no GPS-lag, strange rumour...
Great to hear that new TomTom maps are on the way

I tested the GPS with TomTom 7.450, 4 times now, 4 different routes, all perfect, no lag at all, and a very fast fix. Even when I was looking for lag (because of this thread I was watching the screen/road carefully), I didn't see lag at all. The video performance, that's the real problem of this device.

The rumor started because people believed that because the HD uses the same chipset as the diamond and pro it would lag too...This is not the case. I used Live search gps maps all day today at work with no lag.

I have no clue...the GPS reception strength is leaps and bounds above the Diamond and Touch Pros. Fix time is dramatically quicker. I can get a fix in buildings with my HD without being close to the window! I could never get a fix indoors with my Touch Pro..even flat up next to my window.
GPS signal strength is affected by the radio used by the device. Perhaps they use a different radio version? Same thing can be said about 3G signal. It is also affected by the radio. We know because we have tried many different ROM on other device and know for a fact that different radio gives slightly different results.

the fact we don't get it - doesn't mean it is not true! If you disagree with the result because you have a gps lag IN YOUR TOUCH HD - please report it in details with some experimental evidence.
...maybe the diamond gps antenna has a low S/N, and it has to be filtered by averaging multiple fixes?
Since GPS lag seems not to exist on our touch HD, can somewone then please tell me if the following behaviour is normal (for google maps)
When I drive at a speed of 50 km/h (approx 30mph), google maps shows the dot consistently 10 to 15 meters behind my current position. As soon as I stop (for a trafficlight), the dot catches up and displays my location rather precisely (there is always some error ofcourse).
So during driving, it is quite precise, except for the fact that it is allways 10-15 meters behind me...
Is that normal or is that the fabled lag?
(haven't tested tomtom yet, will use that for navigation anyway, so I am not to bothered by the behaviour of google maps)

I think the software itself is the problem, not the device. I have used Google Map for driving only three times. The second time I used it, the dot did not move at all! It stays at the point of departure throughout the trip! This was on my Athena. When I used a proper GPS software including iGO and TomTom, I had no problem at all. Even when I'm travelling inside a undersea tunnel, the current position moves alone. Obviously this is done by the software extrapolating the most likely position based on the last known speed.
And we cannot forget that the windshield of the car maybe can be a factor for the lag

Sorry, my English is not so good as yours. But does it mean now you can by the Software TTN7 and the maps too on the website from TomTom?
You can not purchase the tomtom application, but you can purchase the maps if you have the program installed and working correctly with tomtom home. Currently only tomtom home version 1.5 allows you to sync your device as the TTN7 application has NOT been officially released by tomtom for the HD to my knowledge.

I am seeing the same thing on my HD, I could not get a fix in my house on my TYTNII or on my Omnia, but I can with my HD, and as I posted before I have yet to see the "lag" that has been talked about
My device works fine with Copilot 7, with no lag.
Lag however IS evident on Google Maps. I think is is simply Google Maps that causes the lap by slower page updating. Considering that this is an "online" programme, I think that it is reasonable to assume that such a programme will not be as instantaneous as a dedicated programme.
That's why you pay good money for a faster programme!
First of all...
I completely agree with the ZERO LAG thing and also while the parts of the HD are almost identical HTC has done a lot of optimization, mostly the way the software communicates with the hardware, which is where the GPS lag was resulting from in the first place.
Good to see how fast HTC picks up some things (while other things take years but that is beside the point) as the Diamond is only a couple of months old and they already fixed so many issues and improved so much..
Second thing though, I have not been able to get a lock indoors, but at home and at work I got a couple of stories above me so that probably causes too much signal interference.
3G reception is always perfect though no matter where I am...

Same here with CoPilot Live 6 (with TTS!).
No lag, and good reception, even indoors away from a window!!!
Quick question:
For Tom Tom to work on the Touch HD you have to buy separate software? Or does buying a physical Tom Tom device mean you have the privilege of having it on an alternative device (the Touch HD)?
The HD is my first HTC phone so can't comment on previous lag issues, however side by side to my PDA running TomTom 7.4, my HD running 7.9 is about 100 to 150 meters behind. I know they are different versions, will go back to 7.4 to test further, but that is quite a lag.
On a seperate note, how do you get an external bluetooth GPS to work with the HD? The HD seems to have less bluetooth settings than my WM5 PDA.

Hi Stranger, at 50 km/hour you do about 15 m/s. every GPS of the class we use, e.g. not for professional use, has one position fix every second - which corresponds to about 15 meters. All navigation softwares do quite a lot of interpolation and data filtering, as we all know when we enter into a gallery and the position keeps moving or when we are slightly sideways on the road but the actual position is nicely on the road! So, it is not a surprise that your software could be within a second from the last measurement, since it has a full second before having the next one anyway and a full bunch of operations to make (screen redraw, route calculations, etc.etc.)
BTW, Igo does exactly the same.
Peoples,
I have a Diamond and I often use the GPS, BUT I am always suffering from extended periods to find satellites, sometimes lag, etc etc
I do know how to get "around" some of these issues (on Diamond) by using GPS Test, HTC GPS tools, lighting candles, sacrificing chickens....but its a right pain
The question is put to all Blackstone users....do you suffer from these issues?!?!?
Looking forward to your responses!!
I didn't noticed any problem with GPS
i also use an Athena and the Fixe with blackstone is quicker
The HD is quicker than the diamond with initial GPS fix.
are most folk using TT7?

And I could take just between 2 to 11 seconds for fix in Athena. So HD even beats that?
On the Touch HD, the fix is quite fast, usually 10-15 seconds. Then in operation, there's sometimes a small lag, but no more than 1-2 seconds when driving above 100 Km/h -- which is perfectly understandable, since the GPS signal itself is refreshed every second.
GPS location
i am finding the initial GPS location, very quick, keep the quick gps updated.
however when using software like either tomtom 7 or igo 8, position actual and position GPS seem very different. And if at the wrong time, could be very costly re:speed camera's.
other than that, IGO8 blows the socks off tomtom7, just the voice comms alone, then we goto 3d maps and buildings too....
mindblowing, igo8 for the HD! works great
Hi i have weird problem with my GPS.
While I driving (car is moving) everything is beauty and sweet but once I stop my car my GPS is still moving for about 10 sometimes 20 sec showing 2km/h then 0km/h then 2km/h again. Sometimes when I stop car on junction my Gps will jump on the perpendicular road and from time to time my arrow on the map just turn around to opposite direction and the maps sets a new route! Once i move my car everything going back to normal.
I was using first my TomTom and i just thought it`s a map problem although i haven`t problem with that on my Rhodium either X1. So I decided to try Igo8 and it`s exactly this same. Even on the roundabout my gps can jump somewhere else on different road.
I tried all Radios available for HD2, many Roms and just have no idea what more I can do. Many people on HD2 forum in Poland have this same problem.
I also tried GPS fix cab downloaded here from xda but no luck its ever worst.
I can add that i'm getting GPS fix in few second so its good the problem is just my gps is moving around.
PS. Very, very rarely have no problem with this jumpin gps around. But is like 1/30.
Do you have access to an external Bluetooth GPS receiver you can test out? That could eliminate or isolate some possibilities.

hi,
are you using the 'gpsmoddriver' software, that is floating around here in the forum?. its made for using the compass data when no gps fix is available. it causes such failures in igo and copilot on my hd2. after uninstalling it gps works much more percise to me, when im not moving.
regards mad
Happens with mine as well. I have replaced my HD2 and it seems that the 2nd unit acts the same. tried various ROMs/RADIOs (official/cooked) - nothing seemed to fix this.
It's quite funny though... most of the people rather paying attention to the fix time instead of the accuracy (which is quite bad imo) in addition to this weird phenomenon. I doubt that the AGPS is somehow related, but it will be nice to know how to disable this feature, and try to acquire the signal without it. maybe this is the cause.

As i said before : i was using it. I had feelings its jumping around the places more than without it so I uninstalled it.
Tried to email HTC regarding this. they claim that their HD2's don't exhibit this behavior, even though I've tried two different units, from different batches.
I don't know what to do... this drives IGO nuts - it causes igo to switch lanes, directions and having the route recalculated without any good reason.

Sometimes its just pointless to talk with those dickheads.
They ll never say true.
With pink camera was this same. They were saying at the beginning that they have no problem with pink spot at all. And what was next? We need just more people to email or ring them.
Most of them even not using HD2. They've seen for few minutes and think they'll know everything about it.
It was so many bugs with this device they just dont want to hear about another one!
In addition to that, both of my units tended to show different position and altitude readings each time i powered up igo or google maps. while exhibiting the differences I obviously didn't from my current position, not even an inch.
to try to make things clearer. that's what I did :
loading igo -> acquiring signal within seconds -> getting a certain position reading with altitude of 11 meters (for example) -> quit -> reloading igo -> acquiring signal within seconds -> slightly different position, altitude of 75 meters or a negative value (for example).
even the small blinking dot in igo (which determines the actual gps mark) doesn't fit to my physical location on the road which I'm currently driving on. it sometimes blinks few meters to the right/left, and sometimes it tracks behind the guidance arrow (as it should be).
Could be
Simply a limitation of GPS. I have seen it on other GPS's. Garmin etrex. Try walking with one and even thou you are walking in a straight line it plots a zigzag path. More satelites (10+) should reduce this issue.
Basically the GPS is only accurate to a certain range from +-50m to +- 2 meters depending on the no of sats. The location is detemined by timing from when the signal was sent to when it was received. Calcs how far away the sat is (Speed of light??). It is possible you care getting a fluctuation in your current location. Eg
Sample 1 says you are point a.
Sample 2 says you are 2 meters to the right.
Sample 3 says you are 2 meters to the left.
Still in the +- 5 meters but the gps is plotting you moving backwards and forwards.
Guys, it is a problem everyone has, gps position is not as accurate or stable on the hd2 as on most other htc devices. And with an erratic gps position automatically comes an erratic speed. Don't know yet if it is because of a different gps module that's inside the hd2 or because of the inclusion of crappy gps drivers. Will try to find out soon....
Anyway, gpsmoddriver is not the cause of this problem since the problem is also on an hd2 without having gpsmoddriver installed. Because of the functionality of gpsmoddriver to improve the gps readings, in some cases it can amplify your erratic gps position, and that is also what some of you have been experiencing. Remember you can always use gpsmoddriver to add the hardware compass functionality to your navigation software, while additionally configuring gpsmoddriver to leave gps data untouched so it won't make the erratic position and speed worse. For more info or help, please visit the gpsmoddriver thread: http://forum.xda-developers.com/showthread.php?t=571266
EDIT: Of course the HD2 has a new snapdragon chip which has built-in GPS just like many previous generations of phones. Most likely qualcomm changed the way gps works in their new line of Snapdragon processors...
The movement of vehicles around you or even the movement of the sun's rays on buildings nearby can distort GPS signals. The GPS navigator software tries to rationalize this distortion and that usually appears as a movement when you are still. On the other hand, if you drive into a tunnel using TomTom and some other software, you will often see yourself driving straight on in the tunnel well after the GPS is receiving no more satellite signals.
In top-of-the-line built-in navigation systems, the GPS data is supplemented by inertial guidance. (Someone could create a similar supplement for the HD2 The supplementary information allows the system to reconcile the GPS information with information on your car's actual movement.
But for us mere mortals, we just have to live with it.
Well... this particular gps chip is quite useless, then. if my navigation program has to recalculate the route each time I stop at traffic light, then it seems that I either have to purchase a usb-based gps to pair with the HD2, or replace this device. I counted on it to perform well.

Complain to HTC, perhaps if they get enough complains they will come out with a hotfix or a rom upgrade that fixes it. Nobody said that the hardware is not that good (though it's possible), but it could also very well be a bad implementation by HTC!!
Already did.
They have obviously denied my complaints.
thanks again, anyway.
I noticed this behaviour yesterday night, at about 10pm. I was playing with NoniGPSplot, and while I was completely still (and freezing me arse outside believe me), it was tracking a movement back and fro and all around in small step, keeping track of me traveling some meters still while I was standing in the same point.
It was night and I was in my big yard, so no sunrays nor moving vehicles around nor buildings over my head.
I think this behaviour is very well hidden in tomtom since it automatically puts you on a road, and "smoothens" the gps data by making you follow that road no matter what, but a "realtime" software like nonigps tracks that all so well. Gonna notify htc about it now.
Guys, let's not go overboard on this. Non-military GPS is only claimed accurate to around 20 metres, regardless of the quality of the receiver. It's the US Defense Department messing with your HD2, not HTC.

Yes, absolutely, I've noticed the same behaviour with all three of the BlueTooth GPS I used in the past. So, I would not be too quick to blame HTC for this.
my touch cruise's gps receiver worked with static navigation enabled to avoid this false movement. maybe this is just a usual behaviour?
Agree to that.
But regardless of the fact that the thing is not a military GPS system, It should do it's work correctly as for me the GPS is almost useless when driving slow or within a city. My 2nd phone (HTC DIAMOND) and 3 personal navigation devices are mounted in my car to compare and all work fine when the HD2 isn’t .
The GPS looses all the time the fix to the satellites and then quickly gets the fix back. when using a GPS monitor you can see that the satellites constantly moving really rapidly. (moving --> getting fix and loosing it again)
This is for 4 other reference devices which are running simultaneously not the case so it seems really an issue with the GPS device.
I tested this with different ROMs (1.44 Vodafone, 0.6 dutty WM 6.5.5, 1.66 stock and another one I cannot recall the producer anymore.)
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

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.

quoting my self...
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.
I have been using my HD2 with differnt 6.5 ROM's (lately mhostly Energy's Max Sense), and that has never been a problem. But lately it suddenly has started to mess up. Either it locks up the phone when it's trying to get a fix (around 20-40 seconds after clicking the TomTom icon) or it can't get a fix and complains about bad reception, and asks if I am indoors. Then sometimes I actually manages to get a fix, and it will loose it after a while or lock up completely. Then it can take a day or two (it doesn't seem to matter how many soft resets I do) before I can get it working again.
I have another, very simple GPS program called GPS Speedo (use it to test speedos on bikes and cars), and that seems to work all the time. But I have tried reinstalling TomTom from the ground up several times. This doesn't change anything.
This has been intermittent for a while but getting worse and worse. So I tried to install the latest official ROM (from October or November 2011), and that works without a hitch. Does anybody know what this can be? Driving me crazy... THis weekend I have been navigating through Sweden with my Adam and Igo (which was the best I could find for Android) and I found out that I really don't like any other nav programs than TomTom very much!
