My diamond GPS does not work

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

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

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

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

no problem using mapking...

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

No GPS reception

Can someone please help me?
I have tried these programs:
Tomtom 6
Tomtom 7
GPSdash
BeeLineGPS
WMMiniGPS
GPS tuner
Google maps
I'm using the latest TLR ROM. My GPS setting are default. Com4 Baud rate: 4800.
Here's the problem. The programs seem to find the receiver and seem to find the satellites. (10-15). But I can get absolutely no signal at all. Indoors or outdoors.
I'm getting quite desperate

Have you used any of the tweaks for GPS? I ask as I did but my signal kept dropping - so I turned the tweak off and now it is fine.
I would also suggest using the QuickGPS application to get the Satellite information quicker

I've tried disabling agps. Didn't help. And yes I have used QuickGPS... but no luck.

Any suggestions? : [

Was it the first try? When I tried first it was 6-8 minutes. Where do you try? In the outdoor?
Have you ever used it?
TB

Do you have correct setting "GPS is managed automatically" ?
When I set to GPS is managed manually, I could not found any way to power on builtin GPS. You have to check box "GPS is managed automatically". I think, it may be point of your problem

I had the exact same issue dude... TomTom 6 didn't work so I installed TomTOm 7... still no signal... even with QuickGPS ran...
Google Maps didn't work either....
I'm not sure what I did in the end... took out the battery, set GPS to 'let windows manage automatically' and ran Quick GPS again.. then run TomTOm 7, go to the 'GPS Status' screen which shows the sat signal charts and stand in a wide open area for 5 mins.. ever since then it has worked fine
all the best.

btw you have to make sure your system date and time are accurate coz otherwise it'll be searching for Sats with a wrong reference to the Sat almanac..

Yes, it's set to manage automatically. I've been trying to get a signal by the window, I left the device just sitting there for more than a half hour and still nothing. I guess I'll have to try longer while being outdoors. Hope it helps... but thanks for your help.

I did that too and it didn't work for me. You have to be outside for the 1st time GPS fix and make sure you run QuickGPS before that. Ohh yeah use TomTom 7 to detect the signal... I find that the most reliable somehow... and be sure it's configured to use the built-in GPS receiver...
I know it feels odd... I nearly sent my unit back for warranty because I was very convinced that the patch antenna was somehow disconnected from the chip. lol.

I had the same issue at one point, due to my fiddling and inadequate hacking attempts!
see if you can track down the HTC GPS tool (it's here on XDA somewhere, but i can't find a link at the mo) and run that.
Chipset should be set to Q7200 (yes i know its actually a 7201A but it works the same) and com port to com 4.
Tap the open port button and you should see the GOS info scrolling through the grey window in the program.
If you see nothing, check the external GPS settings
program tab should be com 4
hardware tab should be non and 4800
last tab should be ticked.
if you still get no GPS info scrolling through the gps tool, then it seems you have the same problem i did. Sadly, i had to hard reset it to get it working again, but it has been perfect ever since.
FYI, this started happening once i had turned aGPS on, and even turning it off did not work for me, so if you have to hard reset, i wouldn't bother ever turning the aGPS on again.

where's the option to turn aGPS on/off?
I just remembered how I resolved my issue... I put a SIM card in I had previously been trying to use it with WiFi (to update QuickGPS) but once I had a SIM in there, the GPS worked. Could it be because I'm now using aGPS? hmm...

you need to install schaps advanced config tool to get to the setting to turn aGPS on and off again.
it seems to be off by default btw.

I also kept lossing the GPS signal with this on every few seconds. So I turned it off for good

did you maybe install voip on your diamond? If so that's your problem there. Hard reset you diamond don't install voip en there you go.

It worked! Thank you all.... I had to sit for half an hour in direct sunlight but it was well worth it... I'm new to gps... do you have to do this with every new gps receiver or is this just another great feature from HTC?

I'm, having the same probelm here.
I'm on my second diamond as the first one (a HK version) had a fault with the internal speeker. On the First phone the internal GPS worked fine with both TOMTOM 6 and Google maps. The initial setup only took about 30 secs.
With the new phone (UK spec) I have tried TT7, TT6 and Google maps. I have also run quiick GPS, hard reset and enabling and disabling assisted GPS using the advanced config tool.
Is there anything else I should try or is this likely to be another hardware issue?

Solution To Gps Problem
if you installed VOIP you should hard reset...gps dead...:-( no other solution.

Help! My Diamond GPS reception is MUCH worse than on my Touch Cruise
Hi,
I've just got a Touch Diamond, and the GPS reception is absolutely appalling. I have hard-reset twice, after which I've done nothing except download a QuickGPS update, but still the signal strength and its ability to connect to satellites is completely inconsistent and unreliable, even outdoors. I CAN get a good signal occasionally, but it's very rare. Most often I get no GPS signals whatsoever, or else I get just a couple of weak greyed-out signal bars in TomTom.
I can lay my Diamond down next to my Touch Cruise (both have identical TomTom 6 software loaded from the same CAB), and the Cruise always launches the app faster, finds the GPS device faster, AND finds adequate satellites faster. The Touch Cruise has a lot of problems, but the one thing it has always been very good at is GPS, and it has NEVER failed to find adequate satellites in TomTom 6, even indoors. It always takes well under a minute to do so, too. It's surely not unreasonable to expect at least the same level of performance from the next generation of device. Why should the Diamond's GPS performance be demonstrably so much worse?!!
Nine times out of ten, my Touch Diamond will simply sit there for an hour or more with the TomTom status bar reading 'Waiting for valid GPS signal...". Quite often when I open the GPS configuration option in TT6, it shows absolutely NO SHRED of a GPS signal whatsoever, even outdoors. (My Diamond and my Cruise have identical GPS settings in both Windows and TomTom, by the way).
The annoying thing is that the Diamond's GPS HAS worked on a couple of rare occasions, and the signal strength has been at least as good as on my Touch Cruise. The Diamond is much worse at holding the signal however, and is totally and utterly unreliable for navigation. It certainly isn't the 'Ultra-sensitive GPS' that HTC's marketing promised - it's nowhere near as good as the GPS on the Cruise, which is the previous generation! The Diamond's GPS DOES work well on very rare occasions - it's just that 95 times out of 100, I'm not getting anything at all. This makes me wonder if it isn't a WM 6.1 compatibility problem or a conflict of some kind. It's almost as if Windows is having difficulty activating/waking the GPS fully. When (and if) it finally gets going, reception is actually very good.
I have also downloaded the HTC GPS Tool as someone here suggested, and it reveals the same results as TomTom - I usually get either no satellites at all, or I get two or three red satellite status bars and a message saying 'Fix not available'. It ALWAYS shows a data stream coming from COM4 though, so there doesn't seem to be any problem actually finding the GPS device. On the rare occasions when I have got a usable GPS signal, the HTC Tool then shows two or three red status bars and three or four green ones as well. During those rare periods, Google Maps can also find anything from three to ten satellites, even indoors. However, the next few times I try the Diamond's GPS, nothing will happen at all - it's suddenly as if all the satellites have fallen out of the sky.
By the way, would QuickGPS make ANY difference on the Diamond? As other have pointed out, aGPS is disabled on the Diamond by default. Aren't QuickGPS and aGPS the same thing? I don't know. But if so, surely the QuickGPS data is useless on the Diamond?
Does anyone have ANY idea how to make GPS on the Diamond work as well as it does on the Touch Cruise? Does anyone know why it doesn't already? Has anyone else done a direct comparison between the Diamond and another HTC device using the same GPS software?
I really like the Diamond, but it's incredibly frustrating that the GPS is unreliable to the point of being unusable. At the moment, I'm having to carry the Cruise for GPS navigation and the Diamond for everything else! Certainly not what I paid for. It should do this stuff straight out of the box. Since it doesn't, I can only assume my device is faulty so if I can't get it fixed by the weekend, I'm returning it for a replacement.
Thanks,
Rob.
P.S. Sorry for such a long post, but I needed to vent.

Hi there, I'm having the same problem as RH Photography.
All the programs are trying to communicate, but no fix at all. Once I got a fix, but only 4 sattelites, when in my car GPS BT had fixed to 9!
Will try hard reset and install HTC GPS tool an try to fix

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

GPS SCAN software

I dont know about others, but I've been having problems about my TTN6 acquiring gps signal. What I would have to do is to open my GoogleMap and scan my location there and then open my TTN6. Even the GoogleMap is having a hard time. I have my setting on Com4 and 4600.
I also use QuickGPS and always updated. Not really sure if it is because of cold start but i doubt it. There are times that I'd be using my gps already and I'd have to soft reset my phone(due to alignment issues) and when it comes back on, I would take awhile for it to find a signal(even though i'm on the same spot when I soft reset the phone).
Any help if appreciated.

Try another radio! Radio has alot to do with your GPS fix, big time!

The tricky thing with radios is that they are different for every ROM, location and provider! So realy the only thing to do is try acouple out! Or go to the Ultimate Radio thread and read to see if someone from your area has recomended one or two! Here is the link to the thread! http://forum.xda-developers.com/showthread.php?t=393182

Ok, thats far away and much warmer than Minesota! Yea I dont know any for California! There should be some suggestions in hte radio thread though! Sorry, wish I could help you more!

not sure if there's a difference, but on my device, i have set it to com 4 and 9600 and things seem to work fine here in Malaysia and in my travels to Indonesia.
my first GPS lock took some time and doing, and i finally got it working after i ran this "GPS Test" program. Forgot the original thread & poster i found it here, but here's a post with the same. http://forum.xda-developers.com/showthread.php?t=374349

I had a similar problem. Not being comfortable flashing another radio, I tried a program called Franson GPSGate. It allowed me to use mulitiple programs that utilize the GPS signal at the same time through the same COM port.
I also get fizes in under 15 seconds when I have GPSGate running first. (it primes the GPS signal and keeps it ready for programs that need it). Just another option.

agreed
GPSGate is a great program. Trialware though. I have started tinkering with a program called "AmazeGPS" that will give you turn-by turn directions, and update your route as you travel, unlike google maps. definetly not as handy as google maps for local searches though. best used if you have an address already. The Radio on your phone does affect GPS, as well as all the other connectivity areas (data, phone, bluetooth, and even wifi, i think). if you are looking for something with good connectivity, 1.71.09.01 is an awesome choice. the tradeoff is that it is a bit of a battery hog. i am assuming that you will be using this in a vehicle or something, as gps itself is a battery hog, and if you plan on using it frequently, you probably have it plugged in somewhere. I live in Arizona, by the way. hope this helps!

Try the attached program, if you are able to see the satellite signal...

I live San Diego, using the PC.Ultimate.V16 rom with Tomtom7. I have my GPS configuration with other NMEA GPS, 57600 baud rate, COM4 and I get a connection in 15 seconds.

I think this question was just asked in another thread.... use GPSTest and then when it acquires a signal open up TTN6 or 7 annoying I know but it works for quite a few people

Excellent
Nice the GPStest, now i try to make functionally mi Googlemaps...
Tks

Here is my advice... I get that same problem sometime in my TomTom (I used to use 6.. but now using TomTom 7)... I installed that GPS Toggle that is a start menu item... It is nice.. it says GPS OFF or GPS ON.. When you turn it on, it says "SEEK : XX" XX beign the number of sats it is searching for... Then when it gets a lock it says "LOCK : XX" and also shows how many "bars" you have.... Sometimes I use it to just test out the GPS function w/o loading TomTom... But I have also found if I turn the GPS ON with it before loading TomTom it locks on faster (a lot faster)... I think it sort of jump starts the GPS chip to lock on faster... It is the same software you have to use if you have a HTC Mogul and want to use TomTom (For some reason TomTom doesn't see the GPS chip in that phone w/o this little program or something simmilar)...
I attached the one I use as a cab.. Just copy it over to your storage card... use file explorer and run the cab file... Then after it is installed do a soft reset... You may have to go into the Today screen options in settings and put a check infront of it to see it on the screen... Hope this helps

gps issues (still not fixed)

My gps only stays connected for a couple minutes then it looses its signa. I have to soft reset to get the gps to work again. could this an atenna issue?
EDIT:
So after hard reseting again and trying again, I've discovered that sometimes the gps will connect but sometimes it won't. If the GPS won't connect, I have to soft reset multiple times until it connect again. Then if I soft reset again, it sometimes doesn't work. So obviously it isn't an atenna problem, but I've got no idea what type of problem it is. Help!

..which navigation program do you use?
Before the signal gets lost, will the screen be dark?

I have no problem with signal - 14 satellites even in the city (Prague) is nothing suprising...BUT! I'm experiencing quite big gps lag! :-( Tried lot of roms - stock WWE, tess v1.1-1.4, energy...same result - for example I'm driving through crossing but TomTom shows I'm at least 30m before it - it's about 1 second when I'm driving about 50 km/h...when I'm driving faster, it's much worse...especially when I was abroad that was really annoying

I use TomTom 7 but this problem also occurs with other programs like gps spot. My screen doesnt go black. Also sometimes my gps wont work even after a soft reset

lol, i have problem too - my gps works, but can't see any satellites

So has anyone found any sort of solution because GPS is kind of important and I use it a lot.

I use iGo. At first, I was also having problems finding a satellite. BUT ... after searching the menus in iGo, I found the settings for the GPS. like COm and baud rate. So what I did was to search the frequencies and it found something at DOM 4 etc. Every time I start iGo, I have to do that. Should find a menu for the GPS settings. Do an autoscan and enjoy. Hope this helps

So what I did was to search the frequencies and it found something at DOM 4 etc. Every time I start iGo, I have to do that. Should find a menu for the GPS settings. Do an autoscan and enjoy. Hope this helps

Hmmm... iGO should memorize port and baud settings... Mine does...

I know it should. But every time I start iGo, the default is saved. That is, I think, port 1, baud 57660 I think :-?

In that case I would recommend to add the GPS settings to your SYS.TXT:
[gps]
set_messages=0 ;optional - this setting stops iGO from changing NMEA GPS protocol settings
port="4"
baud="38400"

will do. Thanks a lot!!!

After further investigation and a hard reset, I've discovered that the problem occurs because of TomTom 7. Can anyone recommend another GPS Navigation program?

iGo = I use version Nav N Go iGO 8 R3 - v8.3.2.83157 (Apr 3 2009), but there is Nav N Go iGO8 v8.3.2.91972 (May 28 2009) which also works fine

Has anyone tried v8.3.2.93112 (Jun 8 2009)?

poor gps signal
Hello
I have similar problem lately. I say lately because my GPS signal was perfect! It would have at least 5-6 satellites fixed inside home even driving on Manhattan was perfect never lost signal while dedicated GPS device like tomtom one would not have signal. But lately for about month I have problem getting signal inside home even outside is problem sometimes. for example when I update weather on HTC sense it wont be able to get my location, also google maps wont be able to get gps location inside home and after a few min of waiting it will get outside, another problem is Nav N Go iGo 8 V 8.3.4 Aug. 13 2009 version. similar symptoms wont get gps signal inside house and loosing signal while driving on a wide open area where almost no trees and no buildings around. the strange thing is device is in perfect condition never dropped and use same stock Rom ever since it came out same radio and same Hard SPL. I did hard reset few times re-installed radio but problem is still here. I would have blamed Rom or radio if I was not sure they ever worked in this case I'm very sure it worked perfectly with those software before why wont it work same way now? is this antenna problem? anyone ever had to open HTC pure before? is there a removable GPS antenna that could become loose or bad connection? any ideas?
