very strange experience today (and just during traveling in the US !) . I have installed TomTom since some weeks and it worked always well. Based on the suggestion of the forum I never never never touched the GPS settings. Now I bought a map for the US as traveling in NY. First day no problem .. tomtom went fine leading me from Airport to the Hotel . Big problem started the second day. I started the Kaiser and TomTom and the TomTom start screen showed me first time ever a message (left corner of the screen) NO GPS DEVICE .... hmmm . I waited for 10 min but not satelite were found.
I softrest .. but no change . But now it got even worse ... TomTom starts , Message NO GPS device showed up and 1-3 min my PDA makes a softrest !!!
This behaviour is fully replicable ..
I even did a hard reset and installed back my back up .. with exact the same problem
Please I need help .. as my travel still goes on .
I would re-install Tomtom , but my CD is at home .. somewhere I can download the SW to do a hard reset without installing backup and install TomTom from scratch again ?
Or is the GPS chip now broken in my device , any idea ho to test if the chip is still active ?

HArd Reset and do not install anty back ups as thats most likly the problem here! you can install TomTom from this rapidshare link! Enjoy http://rapidshare.com/files/56585274/6_032_8351.rar
I had same problem one week ago. I formatted several times but didnt work. Finally simply used QuickGPS to download sats positions and all worked again.
ps. IN my case when I started any gps program (tomtom, igo, cruxview or any program that opens com4) resetted my kaiser
quite strange behaviour ...
- I hard reset and install just Tom Tom , no other app , same result, TomTom did a softreset after 10 sec
- I hard reset and install Mobile Navigator 6, no other app, same results .. MN6 soft reset device after 10 sec.
- I hardrest and install a one week old backup with working Tomtom installation, same result... device reboots after 10 sec.
Thanks to Daniel (your Last name should be actually Hero) I updated quick gps ... now it works like before !!!
But strange enough , I did a GPS quick update just the day before yesterday ..so just one day before this errors came up.
Does this mean,... do not trust you Tytn II and you are in deep **** when this hits you in an area with no GSM coverage ... so no navigation when you cant download GPS quick ???
Not sure if I like this .. plus I am now unsecure if/when this error will come back. I thought Quickfix is just to help you getting the sats faster ... not that your full gps device is not working without GPS quick ...

Hi.
Happy to see your problem was fixed. I ve a friend that uses the gps and hasnt event used quickFix because hast set any connection setting so I dont think this is the problem. In my opinion quickFix stores its info in gps chipset (because of it the problem isnt solved with hard reset) and sometimes this info is corrupt (partial download or any other problem) and makes the device to freeze. Refreshing this info solves the problem...
hey there...
i have a problem with my GPS in my diamond
i installed the SWIFTBL WWE DIAMOND ROM V4.0 - CE OS 5.2.19965 (BUILD 19965.1.2.3) ROM
but now my tomtom cant find any GPS signal and niether can HTC GPS TOOL..
Am i doing anything wrong or is it a problem with the ROM i Upgraded from a Danish ROM
Thanks in advance

Did you do a hard reset AFTER flashing?
yep, it happened to me also, an hard reset should resolve, in any case I suggest you to install the utility "GPSTest" (google to find it).
that program is useful because it is able to "renew" the gps status, after installation just launch it (outside of course) and let the program to automatically check your GPS status (1st time it can take 2 or more minutes), when you see at least 3 sat aligned simply close the program, shutdown the phone (NOT soft reset) and then after reboot launch tomtom and you'll see that it will recognize again the gps module.
bye,
davide
i dont think it is fault that you did not do a hard reset after flashing your rom, neither did i.
You should run the htc gps tool with cold start for a while (3-4 mins minimum), then ur TT can find gps.

The same story here, except that I used GoogleMap. It took a long time for GPS to get a fix and when it did, it found only a few satellites. The reception was also poor with a lot of lagging. And yes, I forgot to make a hardreset after flashing.
I just installed http://www.efficasoft.com/gpsutilities/index_wm_ppc.html and this program got an immediate fix to 12 satellites. I then rebooted and noticed that also GoogleMap was OK now. Why? Someone else may explain.
Untick "Auto search Bluetooth GPS receiver"
Set "COM Port" to COM4.
Set "Baud Rate" to 4800.
hello everybody
im having a very wiered problem since today, i have flashed the new 1.93 NLD stock rom, and the gps decided not to work anymore, i did everything possible, hardresetting, reflashing the rom, but nothing helped, i also installed this HTC tool, and let it running for a while, nothing changed, i deiced to leave google maps runnign for a while, it turned a message saying that my GPS device is having torubles finding a GPS signal.
does that sound familiar to anybody,,, actually what makes it wierede, the programs can see the GPS chip, i mean in tomtom and google maps, but only the device, no signal.
Best regards
Kevin
Always remember to do a hard-reset after installing a new rom.
- I have tried several times that my gps were "stuck". My sollution is the Htc Gps tool (Find it here: http://maritime-billeder.dk/htc-diamond.html). With that you can choose to do a warm or a cold start. This gives the gps chip a kick, and almost always fixes the problem.
Greetings

Since I bought my Diamond, last week, I haven't been able to get a single fix.
Even worse, although my GPS is detected as running by every GPS soft, there is only one sattelit bar active at a time.
(about 10 satelits are being sensed, but only one is actually sending datas to my device, every time...)
I've never expericenced such problems with my preivous triny. There were always at least 3 or more bars moving up and down at a time, and at the end I could get some fix.
- either it is a hardware problem and I got a crap GPS chipset...
- or it is a setting problem with my ROM.
By the way, in the External GPS settings screen, I have strange infos:
Port GPS: com4 which is normal, GPS Material Port: None!!
baud rate: 4800 (which I think is very low, but I heard everybody has got the same)
What's wrong with my device?
Seems to be lots of posts on this issue...a nice simple one is to flash a new radio.....if that doesn't work do a Hard Reset (to be sure!) and restore to minimum and see if it runs.....then move on from there....
I've been having a similar problem with my Raphael (it takes a million, billion years to get a lock and even then it's only 3 satellites).
I deleted the 2 GPSlog files in the Windows folder, did a soft reset, ran QuickGPS and then tried Google Maps again. I got a lock in about 10 seconds with 8 satellites.
Now, I've only been able to test it once and will have a go again tomorrow but it's easier than a radio flash or hard reset!
Harry
Thanks for the replies!
- I've been doing many hard resets these days, due to some problems with Asian Fonts. So, this is not the problem.
I may go for the radio flashing as u suggest.
By the way, I've noticed you're using the x.x.8 radio, are you satisfied with it? I read many are going back to x.x.5 cause they it has poor performances.
-The GPS log files sounds good. I've never tried this but I may give it a try.
I tried to reset the GPS logs from within the soft I was using, but it did not improve anything, looks like the GPS only receives the list of satelits, but no localisation datas at all...

....I'm about to revert back to the 07 radio (from 08) as it did not give me the same sat pickup as 07....you can also try the HTC GPS Tool and run a COLD start...I understand this wipes the data and restarts as advised previously...

I have a similar problem from time to time.A lot of data received from 10-12 satellites but a fix only after a long long time. In comparison with the Garmin Gps I have the sensitivity of the Diamond GPS receiver is good, but the algoritm is not. Diamond radio is .05
I have the same problem if i delete the log file and update with quick GPS.
It seems that the algorithm in the radio sometimes is not able to converge easily to a fix.
My tomtom was working just Excellent on my diamond, than i did a hard reset and no gps, 1 bar for over 1 hour, so reflashed the same rom again 1.93.405 still same problem, so flashed 1.93.401 and bingo it works again. after a nother hard reset 1.93 401 rom gps wont work angin, this time the 1.93 405 rom fixed it. ( all WWE roms)
no idea why this happend.. when the diamond gps works its excellent (better than most tomtom units) but thants only when it works.
as the gps feature is very importent to me, i now have a back up bluetooth gps incase inbuilt gps fails.
and with out quick gps i find its aloms impossible to get a lock.
I only hope HTC fic this issue if not this will have been my first and last HTC product.
Any tips welcomed
Hi mates,
First of all thanks for the link and the goodies, in fact I had already found some datas since many Diamond users seem to have similiar problems with their device.
I agree this is obviously a mistake of HTC to have put a defectuous part in their phone.
1) My problem even went worse yesterday after I flashed the last HK WWE ROM: my GPS wasn't even sensed by the softs!
No NMEA datas blabla...
2)
many hard reset and reflash couldn't fix the problem. I was about to give up when i found info about that HTC GPS TOOL I had never heard about.
After using it for quite a while, at least my GPS was finally sensed and 'some' datas received, though it wasn't enough to get a proper satelit bar, not to mention a fix...
3)
So now I'm back to the same point: no fix or proper reception available, although I'm already quite happy that my GPS is detected again!
3)
I got back to the same stock radio, x.x.5 but no matter which one I use, I can't see when I'm going to have a a fix with that whimsical GPS!
SOLVED!!!
I finally found a solution to wake up my sleeping (beauty) GPS.
The most helpful infos were in that post below, but I did pick other datas here and there.
http://forum.xda-developers.com/showpost.php?p=2563369&postcount=6
The funniest thing is that this problem looks like a hardware one, but in fact it's all software related. A problem of configuration, due to the A-GPS function probably.
From what I understand, if you use A-GPS (I mean if you really have access to this special service through your phone operator) everything is fine.
If you don't, then you may get into big troubles like I and many others did...
1) make sure A-GPS function is desactivated (nothing to do with the Quick GPS function)
2)
... just follow the instructions provided by the Oijkn on the link above.
3)
delete as well the file(s) GPSlogs.txt in the windows directory
4)
soft reset
5)
enjoy a very efficient GPS
Hello ! (I am french)
I have a HTC Diamond P3700 and Tomtom Navigator 7.910 + western Europe 1GB map.
This map map is not recognized ? How repair ? Thanks
I tried everything and i am jst giving up. what can i do to make this friggin gps work? I followed everything meticulously on ppcgeeks http://forum.ppcgeeks.com/showthread.php?t=36639 without any luck. google maps keeps search for satelites, and nothing. always number is zero. do you have any idea what could be wrong? i am on telus cdma network btw.
hi friend...
1st in which area of this sad world do you live??
2nd what is your mobile operator??
3rd do you have a costant/flat umts/gprs connection trought your mobile??
bye,
davide
i live in toronto. i had blackberry curve before this and the gps was smooooth.
this one is being alil biatch.
i am with telus
the third question i don't understand, but my blackberry curve was also with telus, for a week before diamond arrived and the gps was excellent. i don't know why diamond gps is so screwed up. as i said, my diamond is the cdma version. any help is much appriciated, thank you.
I think to know what can be... I mean that happened something similiar to me, but because I cook a new rom every week the problem has disapperead itself.
Anyway I think it can depend by an old problem relative to a dns library that can be overwritten by some software, like for ex some voip software, this cause the internal gps to stop working.
Just tell me if your gps is detected, I mean if your software (for ex tomtom) searches for sats or it says something similar to "gps not found".
If your gps is detected but the software searches sats for infinite time you must look this procedure:
I strongly suggest, just for have a fast response, to use a software like "gps tool" (download from here): go in an open space & install the cab file, then choose com4 => select "clear memory" => & finally "open", go to information window & wait for at least 5 minutes (you must be patient the 1st time), until you read: mode 2D fix... the bars go from red to green, when you have a fix press (in the 1st page) "nav init", after few seconds you can press "close" & exit the program, now open you favorite nav software & you'll get a fix in few seconds.
Instead if your gps isn't detetced you must look this procedure:
hard reset your mobile, because your dns dlls are corrupted
let me know if you have results... bye,

hey ninja, lol. how's it going
suiller thanks for the help. i am going to give that a try. i hard reset my rom. i am on juicy 2.5. but it didn't change much. do you think if your first option does not help. i should flash another rom, maybe stock rom, and then put the one i want?
it depends... like mentioned above if your GPS works it just a gps cache problem, in fact soon as cooked the gps cache is empty or corrupted, so it must be reinitialized, doing so the 1st time takes long time
instead if your gps isn't detected, you can check in a minute also by lanuching gps tool, it is yet configured to look at com4 (default com port for gps in htc brand, the problem is somewhere else, I mean that probably the problem could be also in the rom you are using, if the 1st procedure does not work, try to restore your original rom, before carrying back your mobile for warranty be sure it isn't "self-mistake" (for ex by installing an "unofficial" rom)
for what I can say I cooked almost everything & just happened one time, many months ago in my opinion 99,9% of cooked roms doesn't touch gps at all, so I sincerely didn't remember what's happened that time

hi. thanks for all the help guys.
i tried the gps tool. i installled it and selected clear memory, open, and it never stopped going through the numbers. same numbers again and again, but when i clicked setting it said mode 2 not fixed.
if i recall properly, the gps message i got from google maps was gps not found, but i am not sure ithat it's the rom's fault. it's very popular on ppc geeks. i tried qualcom method to solve the problem but it did nothing. mdata, info, is saved on my hone but no change. so i will try disabling agps, if no help i hard eefresh, or put another rom, if all faili go to fet it replaced, again.
thanks for all you support
ok, i reflashed to stock rom, tried the gps tool, it keeps showing the same method and won't stop. do i need to wait for it to stop?, cuz when i go to information it says mode 2 not fixed.
i am going to hard refresh, and put juicy 2.5 back on, and wait for your help. if nothing i will take it to the store.
I hope you don't have A-GPS cofigured...this will surely screw up your GPS
in tweak diamond, agps is enabled. when i disable it and go to quick gps, it gives me an error, when its enabled quick gps downloads.
should i disable a-gps in tweak diamond?
sure friend, AGPS should be disabled if your provider isn't able to "provide" you that service, beucase it takes busy over & over your gps chipset
there 3 modes to update gps sats positioning:
1) quickgps, simply it's a database where are stored circles/ellipses made by sats, because they are always the same, that data are predicted, so for this reason those values are good also for the near future (at max 1 week), this is the "old" method used by years to make fixing times faster, even if resulting position isn't very accurate
2) AGPS, this should be the last & most intelligent feature, of course your provider must be able to provide that data, if your provider can do this it simply compares your current position (cell broadcast) with the ones stored in their database, and provides automatically to your mobile (trought a regular gprs or umts service) updates positioning, if your provider isn't able to provide this service your gps chipset will be always busy because it scans the network continuosly and other software like for ex tomtom wont be able to access the gps chipset anymore because like told above it is busy by another application
3) classical method, I call old school, and this is also the more realistic method, even if 1st time can take very long and if you don't use very much your navi software it is very annoying because sats runs fast simply it needs a program like gps tool or gps test to full the gps cache (1st time is totally empty), where will be stored current sats position (circles/ellipses), this method can also be reached with last modern navi software, like for ex tomtom7, you must leave it runs until it finds something, remember that 1st time can take up to 20 minutes... it depends also by region & sky conditions, in general in a good environment (ex openspace) for me & in my experience it never took over 5/10 minutes
so if your provider doesn't provide AGPS service simply turn it off and re-run the 3rd method in an open space and you'll see that something will happen
anyway if trought gps tool you are able to open the com4 port and you see data flows it means that your gps chipset is recognized, you have just to wait, if you want a faster/simpler app search here around for "gps test"... simply run it, it detects automatically your gps com port & starts to discover sats
hoping to have cleared something about gps system
bye,
davide
ok, i reflashed stock telus rom, then i flashed juicy 2.5, hard reset and here i am. i got diamond tweak, disabled a-gps:
with a-gps disabled, quickpgs does not update any more. gives me an error at the end.
so i am going to do clear memory with gps tool, but does baudrate matter? when i turn it on it is set at 5600 should i change it to 4800?
do i need to be in an open area when clearing memory, or it does not matter?
if this wont work, i will go in throug hqualcom, and make sure i have the settings posted on ppc geeks forum. i hope something will turn up.
what is the connection though. if a-gps is disabled, quick gps does not download. but when its enabled it does. does it mean telus supports a-gps or it shows that there is an internal problem with my gps?
thanks for all the help.
i installed gps test. it shows yellow circle and GPS starting up. above it shows hdop 50.00 Fix 1D, and baudrate is set at 9600.
does this also take a long time, or is it a good sign. if it shows this, does it mean my gps is working, but only needs to be reconfigured somewhow?
i was just outside for 1 hour, with the gps tool turned on. nothing. it keeps clearing memory, or so it says, but when i look the same numbers show up. i waited for an hour till it got dark and cold and went back. gps test shows starting up gps but never getsa round to it either.
i duno what to do anymore.
ah, where is everyone?
holy crap, finally, i solved it.
I had the same problem after setting AGPS in Advanced Configuration Tool. Nothing I did: soft reset, hard reset even installing new ROM resolved the issue. Finally I found the problem: Go to Programs-settings-phone-services-Location setting-get settings-On. This allows your phone to tell your GPS where you are. The GPS now finds satellites in a few seconds.

it was an old habit of disabling gps to emergency only. i didn't realize it would screw me over on a pda. well. nice nice nice.
thanks for all your help everyone, you ahve been great.
this means that your mobile provider supports AGPS feature
so it must turned on... well done
I have been using TomTom7 on my diamond for almost a year. First several months it was working fine, just some lags or freezes on roundabouts, which was not a big issue.
Then it started doing this strange behaviour at some occasions: I start TomTom, it finds satellites fairly quickly, I start driving, all fine. Then after some distance it loses coordinates (you can see the blue arrow, but everything behind it is grey and it is not following the route). Sometimes it fixes itself for a short time, then does it again. Sometimes this is all, whatever you do (reroute, restart tomtom, restart phone) it won't come back. Some days none of this happens.
Nothing in configuration had changed, I've been using the same radio and rom for almost a year.
I was really annoyed by this, could not simply rely on tomtom. Now I updated the ROM, and yesterday this happened again
If this was discussed before, please point me in the right direction, most of the threads I found by search were about lags or configuration.
It might be the Quick GPS Programs, I recall having a simular problem where the GPS would work for about 5 minutes then turn off, only turning the phone off then on then running up tomtom again would get another fix, only for it to run for a further 5 mins or so.
I think I disabled the quick GPS in the registry using PHM registry editor or something simular.
It might be worth considering updating the ROM. I'm running BsB's which seems much better than the stock offerings.
I've also had this problem with the latest rom from HTC (regular rom) with the radio 1.09.XX
I've updated to radio 1.15 and the problem is gone.
Thanks for you replies.
I've now updated the radio to one of the latest (1.09.25.23), the ROM was already recent (2.07 Gen.Y). Will test it during the week.
The solution based around disabling of Quick GPS - wouldn' it make the start up time longer ?

Could be error in timezone
Hi all,
I had a similar problem and it appears to be the timezone, by reasons unknown my Diamond was set to a timezone of Stockholm, now that looks ok, but it is not a normal timezone.
I changed it to Stockholm, Berlin, ... the standard timezone and once again I got a fix fast and easy.
The thing that you get a gray screen is that you our somewere in the middle of the earth according to the GPS, you notice this if you could see the coordinates and altitude.
I have iGo in my Diamond, but the problem was the same when using Google maps so it wasn't a problem with the program.
I have also changed my iGo to have a manually selected time zone, because I'm not sure if it might be iGo that made the change for me.
But now all my GPS works splendid, and I have a fix within 15 seconds.
i do have similar problems.. but it only happens when i'm in the dense core of downtown toronto where all the tall buildings are..
I think it's because the tall buildings are blocking the signal somewhat that is why your GPS kept on running out or coordinates and relocating itself again

I am in rural Scotland actually, the only high buildings here are castles which are miles away .. so this must be something different.
Neither it seems to be dependent on the sky nor battery level ...
p.s. testing new radio, so far so good ..
Just some feedback from testing: the original problem seems to be solved, but now I've got something much worse - sometimes TomTom freezes several second after the launch, and nothing can be done apart from restarting to bring it back. Don't know if this is a radio's or ROM's issue as I have changed both. Reinstalling TomTom from .cab did not help.
Anyone had similar experience ?

Hard reset maybe will help
Yes it may, but 3 days before holiday I do not want to be installing everything from scratch. I could try another ROM too if not this.
Tried - atifix, starting with bluetootsh on, wanted to reconfigure GPS setting in TomTom, but can't get there yet ... must be either BT or GPS connectivity

Updated radio to the latest 1.15.25.14 with 1.15.25.35 rilphone, made no difference at all ..
I think I found it - G-Profile service was the cause of the problem. Once I stopped it, TomTom has got 100% starting rate. It's a pity, was a nice small app to have.
