My diamond GPS does not work - Touch Diamond, MDA Compact IV General

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

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

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

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

no problem using mapking...

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

GPS Fix Problems (official HTC ROM)

i have problems with Satalite FIX.
it can take mor then 10-20min (if at all) to get a fix.
i setup my GPS manualy to COM9 @ 4800.
i know (at least) one other user have a simular problem.
HTC, after some e-mails, say that if i DON'T use TomTom software, they can't help my with this isue.
any idea ?
thanks.
Fix
I had some problems with slow fix. I enabled the GPS applet in settings and it was configured at 33600, changed to 4800 and also in Tomtom and miomap settings configured to 4800, after that, very quick fix, on cold start less than 1 min, on warm start just seconds. Try it.
under, settings -> connection -> GPS ...
i set:
program tab:
GPS Program port = GPD9
hardware tab:
Port = com9
boud = 4800
access tab:
mark on the manage GPS Auto.
is taht OK ?
and allso on the navigation program i set manualy com9 @4800
Yep, that's my config and works right...
interesting... i have my settings as follows -
program tab:
GPS Program port = GPD1
hardware tab:
Port = com1
boud = 115200
access tab:
mark on the manage GPS Auto.
with these settings i get a fix in 30 sec to 90 sec...

After a sofreset? Probably not
The "warm reset time" in a GPS is not related with the Port number or the baud rates...but with its sensibility
SAme for me the GPS response can take up to 10 minutes.
I tried your setting Julioski and AriebK but it doesn't help?
In tomtom I don't see where to set the port and the baud speed can you help?
Any other ideas?
after configure the above settings, i get FIX, but after 20-30min of navigation... the FIX is gone, one more thing, i notice that my phone 3g signal drop allso, SR was nedded.

According to HTC the reason the GPS function was not enabled in the first place was a conflict with the GSM signal,anyway try manually setting your phone band to GSM and see if that makes a difference.(Settings,phone,band,select network type:GSM)
What radio version have you installed?
1.35, 1.38???
I have an HTC p3600 Trinity and have also just installed the newest ROM from HTC.
I downloaded the TomTom application from HTC, installed it and everything "seems" fine accept I cannot acquire any signals.
I have tried many of the different GPS settings from the GPS manager, but nowhere do I see a way to change what TomTom is looking for. There are 5 default gps reciever options... (builtin, bluetooth, wired, other bluetooth and other NMEA device) and I really have no idea what to choose if I have to input the settings.
Can anyone help?
Thanks!

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

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

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

Maybe that's why ... sorry couldn't help it...
Are you sure there aren't any other factors involved (like heavy cloud cover, rain, , etc.?) or more than 3 days since last fix (not that this should take 15 minutes - this is more than downloading the whole almanach). Can you check if you have signal all the time, or if you keep loosing all satellite signal? Because if it looses all satellites, he has to start from the beginning with the fix, so it's in a loop until he gets proper signal.
Well there seem to be quite a few issues with the GPS,personally i'm using the Destinator 6 software ,and here is what i noticed ;
With the official HTC rom :
The software detects the GPS in about a minute and acquires a fix in about 3-4 minutes with the GSM on and a clear sky.
If i softreset the device then 1/3 times it won't find a GPS antenna and i have to manually reconnect and define the com port,it then takes apprx 5 minutes to get a fix.
The weird thing is that when i used Destinator PN i didn't have any of these issues .
Lately i've started using img-32424-mUn and i've noticed a definite improvement in both GPS strength and speed.
i did use following test rom, the gps response is around 1min.
RUU_Trinity_CHT_1.23.751.1_101_6275_1.29.00.11_108_Test.exe
however, by using offical rom whatever config the baud rate or GDP, required 8-10 to get the fix.
the problem is that it's not stable
one day i get a FIX within 1 min, next day after 20...
and 2 days later, not getting any FIX.
i tryed with GSM and 3g ...
i guess the radio (or the GPS part) isn't as we excpect it
sad that HTC dont want to support users that NOT use TomTom.
I think it would be useful if each of us told the others the type of GPS software they were using as it (The GPS software)seems to affect the time it takes to acquire a signal.
Also try using the GPS with and without the radio (Flight mode) and see if it makes a difference.
No GPS Signal & Icon
Hi! I've another problem. I've downloaded new ROM upgrade and Tomtom applications. After waiting for 10 minutes, my device says no signal received. I read from some forums we can adjust some variables but there is no GPS icon under settings\connections folder.
Can anybody help me! I have version WWE 1.23.405.

GPS not being detected by GPS Test and GPS Viewer

Hi guys,
After a few weeks of very limited usage of my Tilt GPS, one day I noted that any application was able to detect the GPS. After reading other posts I noted that the solution could be a hard-reset, which I did, however, even after trying several hard-resets and different radios and roms, my GPS is not being detected by GPS Test and GPS Viewer. However, I noted that when I select COM4 at 4800 kbps (disable scan and select a specific port), the GPS led flashes but I never get the GPS starting message (just a detecting GPS message). Any idea what could be wrong?... can the GPS be blocked or deactivated somehow?...
Any help would be appreciated!... Thanks!
couple things to make sure before returning your phone. When using HTC GPS tool, go into the satelite section and see if you at least picking up 1 satelite. Verify you are not inside a building and you are outside and you are giving it some time. Flash another rom and do these procedures again. If none of these work, then probably could be the phone. Good luck.

You need to be outside to get a satellite fix. It is almost impossible to get a satellite fix indoors. You also need QuickGPS (freeware) which updates the ephermeris info and lasts 6 days. This makes a satellite fix much quicker. Try that.
GPS antenna
The UART baud rate of the GPS port should be set on 57600. Probably the communication can be done at 4800 like the SIRF chinese module but try to put the correct baud rate and see if the handshake works more fast.
Since I use the phone mostly mobile in my car, I just got one antenna from this eBay seller.
This one have full 15 feet cable so I was able to clip on trunk cover, near the rear window. The antenna connector must be fully inserted in the phone enabling the path contact and at the first insertion you need to apply more force (as usual ).
The phone will sense the current flow by feeding the antenna LNA chip so there is no such thing of mechanical device to switch antennas (internal/external).
The sattelite signal almost double and sometimes up to 10 sats can easily be locked and fast.
GPS working again!!!!.... but how????
Guys,
I'm posting as just noticed something really weird, and to be honest I can not find why the GPS is working again. In my first post as I stated, the GPS was working fine (I have an unlocked tilt with HTC ROM). Then somehow, one day the GPS did not worked anymore (I used HTC GPS Tool, and as soon I opened the port, I did not got any messages at all, it just hang! and with GPS Test the GPS was never detected! - in both cases the GPS led flashed!). Now, after giving up with hard resets, going back to the original ROM, updating QuickGPS data, etc. just yesterday, when I on was meeting playing around went to GPS Test and voila GPS was detected again!!!!... and so far is working fine... I have no clue what fixed it! and, I'm wondering if it may had something to do with my carrier... any one has faced something similar?... any idea what happened?...

Intermittent GPS

Hi all, yesterday i've changed the "external gps settings":
COM8 For virtual GPS port and COM 4 as Hardware GPS port, baud 9600.
Today i was using my GPS the first time after the settings descripted before...
The GPS Works, but at regular intervals of 2 sec, then stops for 10 sec (No GPS Found with Tomtom) and works again.....
Now i have 3 questions:
1) Can i solve this WITHOUT an Hard Reset??
2) If i disable the Virtual com port, tomtom DON'T let me choose another COMport (it skips the Comport configuration page) and, when it allows me to select the right port, the COM4 isn't there
3) There are A LOT of comport into "External GPS Settings", some starting with COM..X and others ports named GPD..X ..... What type of ports are??
(Ps: i have already installed tomtom again)
Did you try to disable AGPS?
I have only seen this problem when AGPS is enabled (via advanced config) too
Also the defualt GPS COM ports is 4 and baud rate of 4800 (should be no need to change this) and why mess with external GPS settings when the device has internal GPS?
I have same problem on iGO8 with AGPS enabled.
You guys are right! The A-GPS was ON (strange, i don't remember i've activated it)
If i play with the external gps app is because i would to share the same com port to 2 gps apps.....
BTW when i set the com4 in Hardware port, reopening the app it disappear.
Now i have Agps disabled, External gps app "void" and tomtom don't let me choose the comport (it switch from baud speed to mainscreen)
Hmm, I had no problem at all using GPS at standard settings for:
Igo
TrackMe
GoogleMaps
at the same time!

diamond has disabled agps out of the box.
Hmmm I had no problems the first couple of times I tried iGo when I first got the device. Then I tweaked it, enabled AGPS and all hell broke loose (presumably due to this setting, though not 100% sure since I changed lots of things). Disabled it on my own, trying to back-track, now it's better but I still got problems with GPS lost...
By the way, is there any use setting COM4 to high speeds? Does it reall improve performance?
I had the same problem after flashing the actual rom build from HTC club. I am currently sticking to this one in italian and no problem at all.
P.S.: Just noticed you're from my same city
All ok now, i suppose that if we leave blank the GPS port (no HW port) into first COM screen of external gps app, tomtom skip the comport settings screen, and don't allow you to choose another one.
I've Hardresetted my pda yesterday, and i've seen that out of the box, the diamond has COM4 selected by default.
I don't want to change anything now (i have no time in those days to do another Hard reset) BUT, if you have problems regarding the GPS COM Settings screen in tomtom, try to set the COM4 into GPS PORT (not hardware port) of the "External Gps" app.
hello everyone
i have the same problem of signal GPS lost and coming back after a few minutes of use (i use IGO 8), then lose again, then back again, and so on.
I installed the new flash rom from HTC eclub, (QMR-RUU_Diamond_HTC_FRA_1.93.406.1_Radio_Signed_Diamond_52.29.25.12_1.00.25.05_Ship.exe)
Even if i disable the a-gps using advance config, the problem is still there.
Do you think that problem comes from that new HTC ROM ?
Any solutions?
NO... I had the same problem on old ROM very rarely and solved with Quick GPS , I will see if the problem persist on new ROM...
I had this disconnecting problem too with Tomtom 7,
now with Bepe 0.98 and radio Radio v1.00.25.07, all is OK, no disconnect at all this morning ( 2 hours of GPS use ).
But I don't know what resolve the problem, Bepe's ROM or the new .07 radio
my diamond refuse to accept setting for hardware port and rate......
it always displayed the default (hardware none ,,port 4800)
and always intermittent gps signal...
can u help me?

Never mind the setting. Is AGPS disabled?
yes its disabled...
A bit strange, mine works perfectly with iGo, it even updates the position (almost) continuously when in pedestrian mode.
Perhaps you could try an auto detect from your GPS program to reset the link. By the way, what soft are you using?
well im using garmin xt and navigon...garmin display that the program and hardware is com:4
thank u for being patient with me....
I know Garmin works on the Diamond, so I'm running out of ideas... I remember reading that some VOIP programs screw the GPS. Did you install any such program?
If not, what I would do is back up my contacts and calendar and do a hard reset to see if this solves the problem. A bit painful, but will certainly answer the question whether there is something wrong with your hardware or not.
well.. i have changed the rom to karmba version, and it works fine for the last 6 hours..
gps functioning well.
may be the fault was in my previous rom (SwiftBL-WWE-Diamond-ROM-v5-5-Lite)
thank you very much for your help

(SOLVED) GPS Solution for Diamond- Cooks please look

Hi everyone
I have spent a lots of hours searching for the answer to bad gps reception on diamond, through different forums.I was about to sell the diamond when I finally came with a solution and that is Hard Reset after each Rom flashing.
For a few days I could not get a gps fix, no matter what I did. I tried Quick gps, Gps tool , Google map, iGo8 and Garmin. Somewhere I read that it could be the Rom I am using. So today I flashed 4 different roms including Dutty's, bepe and panosha but no gps fix. Finally I did a Hard reset and viola, it found the satellites within 10 seconds inside near the window on all the different Gps softwares without any problem.
So here is the procedure:
***After a ROM flash finish the usual soft reset and stuff and then do a HARD RESET. Download the data through Quick Gps and your gps should work properly at its default settings.***
Actually I found that Diamond is faster than TYTNII for getting the Gps fix.
Now if the Cooks can find out what causes this behaviour so we do not have to do a hard reset after every new flash.
Please share the findings.
Cheers!!!
********* Ok I have been flashing all the new roms and Gps was not working even with the hard reset. Finally I flashed CT's Beta lite2 Rom, did a hard reset and viola Gps is working flawlessly for the last three days. This Rom is actually the fastest and very clean among all the other roms I tried ( no offence to all the other great Cooks ). Please try it and share your findings!
Well, now i know why i dun have GPS problems...
i hard-reset after each flash ... just a habit inherited while using artemis...
Hi, nice tip
When you had done a hard reset, is the GPS working fine after several reboot ?
It will be nice if someone on XDA or HTC find a solution
Yes its working fine since then and I have done several soft resets.
Fine here. The only thing that made the GPS not work for me was turning on A-GPS.
Doesn't work for me. I have changed my ROM to bElite 0.93, have done a hard reset, loaded quickgps data and still no fix after half an hour on the window.
Try going outside in the clear. If you get the fix then its the location of your window.
try using HTC GPS Tool, it fixed for me once:
http://forum.xda-developers.com/showthread.php?t=360477
install the cab, run it, then choose "Cold Start" let it run for awhile then try using your GPS software again.

HI, ... Hard Reset,- you mean reformatting the internal storage as well? - i've done hard reset but still the gps can't fix location- says in HTC GPS tool - Mode 2: Not Fix
thanks
Mode 2: Not fix...
And the sattelites numbers show just #? Or u can see actual sattelite numbers?
Reason I'm asking is, if you just see #... then ur GPS is scr###d up and the cold start could really help.
If you do see the actual numbers, but no reception bars, then you have to get ourside into the clear sky. Be aware that nowadays windows are protective for keeping the heat of the sun outside. At the same time it keeps GPS for 95% out too.

You haven't been playing around with the GPS settings in the configuration of 'external GPS'? The standard settings are: GPS program port COM4 / Hardware port = none with a baud of 4800. Access tab should have GPS set to be managed automatically. Also, you have not enabled AGPS in any way like with a registry key or the advanced config program?

I have more or less 5 seconds of lag, and the precision is awful...
If I use a BT external receiver connected to Diamond, than I don't have this problem...
It seems that the receiver is refreshing to less, or the communication between the receiver and the GPS software is too slow...

I've fixed my gps problem. I just tried to force change the gps port from settings>external gps from port 4 to port 6 and in my tomtom, i choose other receiver then tap port 6,was showing poor signal- i minimized tomtom, opened htc gps tool opened port 4 at 4800 cold start> gives me error message that the port is closed and it will force open nmea but still fail, in this part i tapped nav init.. then closed it- opened port 6 in cold start> showing all sat in #### instead of numbers. then closed it. then go to settings>external gps> then choose port 4, opened tomtom then went to gps configure and now change it to built in gps... i get full 3d 6 green bars indoor. all ok even after a hard reset. Thanks

So far i dont have accuracy issue. i tried igo8 using bt receiver (SiRF III) compared it to the internal gps- it's just the same , internal gps loads even faster- In TomTom7- if i use bt receiver, some voice instructions is not complete unlike the internal gps which is flawless- maybe it's the rom/radio...
I don't have any problem
"Bonjour" (since I am french !!! )
I tried the GPS with TomTOM V7 = no problem
with garmin XT no pb
First idea
Within the programm window I have a "fast GPS" programme
Do you have this ?
Did you run it ?
Second idea
You should enable Agps in advanced config
On my diamond if I disable it doesn't work anymore
Third idea
Try to see if "GPS utilities" works
Google it it's a basic cab file for showing basic GPS (position, speed, elevation.... )
Let me know

Diamond GPS doesn't fix satellites

hi, i have installed TomTOm7 and Sygic Traffic GPS together on my Diamond and now the device doesn't fix satellites...the settings for external GPS are: COM4 port, baud 4800 (default settings) and the softwares are setted correctly.
What do you advise me to check?
thank you
Try GWatch .5
Getting a fix on a satellite is a problem with the Diamond and Pro. I had this issue with TomTom 7 too with radio v1.02.25.28. I installed GWatch .5 (app found in this forum). Start it and go to GPS (1st button) then to settings. Select COM4: and baudrate 9600 and NMEA then select Activate GPS on the same screen. Select the Check and wait for Valid satellite to appear. On locked, minimize and start TomTom7. Go to GPS setting and select Other NMEA GPS then baudrate 9600 on COM4:
Hope this helps.
i'll surely try this issue...but i think it's a little bit complex way...but if you say that this problem is known for Diamond and Pro..hope there will be changes with new roms and radios!
did you recently upgrade your radio rom?
if so try a gps cold start using HTC GPSTool.
strange thing happened...i just installed GWatch .5 and tried to make it fix satellites...it gets to 8 valid satellites but doesn't fix!I turned off GWatch and restarted TomTom, and in quite a minute he got satellites fixed...after cold fix then only few seconds to fix again satellites...very very strange!Yesterday i spent more than an hour trying to make that s*** fix satellites!
I haven't upgraded radio since I installed 25.05 few months ago...i just had an hard reset 5 days ago.
What exactly is HTC GPSTool?
Thank you
i forgot...i have A-Gps disabled with Diamond Tweak 0.5.3 and in some case i start No-Data to block internet connections just before starting TomTom!
even i have issues the first time i try to get a fix after hard resets. Once i do, its fairly quick
i upgraded hardSPL, made hard reset of course..upgraded infos in quickgps...the fix is now immediate...hope everything goes so well!
SOLVED
Hi guys
Here is my solution.
First you have to flash 1.13.25.24 radio rom sometimes it can be solve the problem.If not you must open your phone with Htc service manual and find gps coaxial cable and check it.Sometimes it can be pulled out.Mine antenna was unconnected and gps couldnot find any satellites.Sorry for my bad english.
