GPS Fix Problems (official HTC ROM) - P3600 Software Upgrading

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 Problems

Hello folks,
I have dutty's WMM6.1 WWE (04/16/08) and radio rom 1.58.26.20
this radio rom was the only working rom I found, on other roms I couldn't get any internet connection
also my gps config: internal gps receiver, com4, baud 4800
Well... when I try to connect to GPS mostly I can wait hours and hours without happening anything. ofcourse I'm not that stupid to try gps inside a basement, so I just do it in an open area
anyway, I tried a lot of things:
- use quickgps for downloading the lastest gps info (sometimes actually works)
- turning the device off and on
- removing the battery for a short period after shutting the device down.
well, the last one mostly works, but now it just doesn't
When I use GPStest I get a pretty good signal from multiple sattelites, the problem is, it keeps hanging on "GPS Starting up". this happens on EVERY gps program I have
so... am I doing something wrong? or is the gps driver just crazy?

I figured out how to get a quick fix with this rom.
1) start>programs>system tools>GPS router to com4 and 4800 baud>enable
2) open quick gps and dl
3) open gps software
If you don't get a fix within a minute use gps test at step 3.
I rebooted my phone for trying this
and... great succes
just 1 minute and a I have a connection, verry nice
The weird thing is, after I fixed it once and leave it in stand by or on, I get my gps fixed in seconds
it might also have something to do with a nearly empty accu (like 35%)
I ordered a big 2800mAh accu now, so I'll hope it will work a bit better
thanks
That radio is kinda slow with GPS anyway I changed mine to 1.64.08.21 gets a fix within 10 seconds at 19200 baud.

Is there a particular reason why you use this baud over any other? Just curious as I had GPS issues in the past, which are solved now.
From my experience certain Radio's work better with certain baud rates, so it really just depends on the radio you are using. I have tested a good portion of the Radio's and so far this has been the best one overall. I can't quite remember but I am thinking that radio you are using now (1.58.16.27) I had problems with mobitv.
Hmm... never used that
I don't have any gprs or 3g access, I just use a prepaid package with this phone.
I only use wifi, because everywhere I come, they have it
the problem on the radio that you're using, is that every time I tried to connect to an AP, it showed me connected but it even didn't say "hello" to that ap... not even after a few times turning on and off the wifi
I've put it now on the same baudrate as you, and I get a good connection

I will have to test the WiFi next time I am around one. I don't ever use it. The only problem that I have really noticed about this radio is that it likes to have a constant internet connection to get the best signal otherwise the coverage isn't as good as other Radio's, but I sacrificed that for the GPS speeds. The only other radios that I have had good success with is 1.58.21.23(really good signal, but GPS takes longer) and 1.58.26.20(which is also slower on GPS, but I think works best at 38400 baud)

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.

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

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 has stopped working - wtf is going on...?

Over the last few days I have noticed that my GPS is not really working anymore. I'm not sure if this is a result of some software I've loaded or whatever, but I've noticed a few people saying that they are no longer locking onto satellites and noone is really sure what they've done - although there is a thread about the new Clove extended battery and many have mentioned that it stops the GPS from working.
I'd like to get everyone who is having problems to post here please so we can try and work out what the cause is. Some have speculated that it could be the radio but I don't think it is, I've flashed every single radio available with no change...
When I first got my diamond, I was IMPRESSED at the speed and accuracy of the GPS. I would get locks in around 10-15 seconds and using TomTom 7 I found it to be extremely accurate with regards to my position on the map.
Now it SUCKS. The other day I drove and it took 18 minutes to get a fix. When it finally did I estimate it was between 50m - 100m inaccurate. Some kind of lag is going on.
As of the last two days, I cant even seem to track ANY satellites. Since then, like I mentioned I have tried every radio and still the situation remains bad.
- I'm running a cooked ROM based on the 1.93.xx.x. (Elite 3.0)
- Current radio is .11 which seems to work well for my push email. (.05 worked well too) Other than that over the last couple of days its just been push email, a few texts and calls and really nothing else special I'm doing with the device.
Can anyone having the same problems please post here with your ROM version and let us know what your experiences are.
Thanks.
I have the same problem
Rom 1.93 - swift.

No.. Its just the GPS data thats used by the gps to get a quicker lock on the satelites.. Which then only saves you time.. It does not cost you anything besides the trafik it uses to update the data..

gps is for free, the "4 days" corresponds to the time which your device
has the almanach data for faster satellite lock in it's memory. after this time
quickgps will download the alamanach data for the next 7 days, and so on...
if you don't use this feature you still can use gps, but obtaining a fix will
take you a longer time!

I have noticed that it is also dependent on the Rom. I am into flashing different roms and have seen different behaviour of Gps with each rom.
But HARD reset is a must after each flash.
Let me know your findings.
Got my GPS working in TomTom..
Steps i took:
1: change in PPC the gps port to COM6 - So still at Baud 4800
2: TomTom - Gps configure - "Other NMEA GPS reciver" - Baud 4800 - "COM6"
3: Closed TomTom
4: changed in PPC the GPS port back to "COM4" - still baud 4800
5: TomTom - Gps configure - "Build in gps"
And done.
I have this problem- the GPS seems to get worse and worse after a hard reset or rom upgrade to the point where it won't lock on at all.
I have noticed that in TT7 a number of satellites are being found (in the gps menu)but they are greyed out. Despite this it just won't lock on however long i leave it.
I notized that I was sometimes unable to track any satellites because I swiched on "A-GPS" in the registry with some kind of editor. After switching it off the problem was gone.
Greetz
Yes, Advanced Config destroy your GPS if you use it to turn on A-GPS.
Try reflashing the Radio with the same build as you are using already. It resets the GPS and did the trick for me.
How can you turn on A-GPS in the registry? Which key is it?
I have the same problems: when I use the GPS, it finds some satellites and not, and back it finds them, and not. When I use tomtom 6, the screen turns grey and colored every 5 sec., because it finds the satellites and not.
Sometimes it works good, but mostly not.
Can somebody help!!!
ROM: 1.35.404.4 NLD
Rom date: 05/30/08
Radio: 0.93.25.NS26
Protocolversion: 52.26.25.09H

There is a little tool which is called "HTC GPS TOOL(S)", dont remember the exact name.. there you can search for satelites using the "cold start" option.. when some satelites are found, then push the "Nav. Init." buttion", dont close the program, just start TomTom and se if it did lock? .. Some reported this method working..

Got my GPS working in TomTom..
Steps i took:
1: change in PPC the gps port to COM6 - So still at Baud 4800
2: TomTom - Gps configure - "Other NMEA GPS reciver" - Baud 4800 - "COM6"
3: Closed TomTom
4: changed in PPC the GPS port back to "COM4" - still baud 4800
5: TomTom - Gps configure - "Build in gps"
And done.

I did things a little differently to yourself, but certainly your general method has solved the problem!
Firstly, and I don't know if this is a result of the radio version I'm running but I only have COM4 and COM7. Running radio .11
Secondly, within TomTom I simply configured the GPS, I changed to other NMEA receiver, selected COM4, and Baud 4800, and then within about 10 seconds, I had a lock. This is after days of not getting a lock at all.
Restarted TomTom, switched back to 'Internal GPS Receiver' and almost instantly locked again.
Problem solved!
I had done many ROM updates and not noticed this effect, I believe now thinking back this must have been a direct result of updating the radio only from version .03 to .05
I will update the thread title.

GPS will not find location

got my pro the other day... and I have garmin loaded up, and its not finding a signal so I have spent most of my day reading all posts I can find relating to the GPS, I have used the GPS viewer and it finds the GPS and once it starts I can see it will not acquire my location I could leave it for 15 mins or so and it wont lock on, google maps will not work, nor with garmin, I have tried changing the ports from 4 to 1 and others but nothing seems to work.
does any one else have this issue, and have they over come it if so how i want to use my GPS...
thanks
set your band rate to 9600
still no good.
tried the GPS viewer google maps and Garmin again...
I have similar problem and what I did is to flash new radio. Currently, I am using 1.02.25.28 radio and seems like the GPS works fine now. It can lock on less then 1 minute in one space but the signal strength is vary from low to high quite fast (not stable).
I tried to navigate with this radio and turned out to be better than the original radio shipped with the unit. But, even with this radio, my old Kaiser GPS still performs better. When I use Kaiser, GPS lock in less than 10 seconds in open space.
BTW, the GPS software is Garmin Mobile XT.

I had the same problem, and I dont know if it is the same problem you are having but check your settings/personal/phone/services/location setting and turn on location setting and all my gps was working again.

your explanation doesn't make sense at all
when i go to phone/services there is no such thing as location setting.
it lists my phone services such as call barring, caller Id, etc...
i'm using Chartcross GPS test 1.04 and set my com to 4 baud to 38400 and it is not working. Google Maps says no gps found.
i am on a stock AT&T Fuze rom... just got the phone yesterday
I also installed HTC GPS tool and those symbols and number mean nothing to me.
no real manual on how to use it unless you're technically saavy and have programming background
i also disabled AGPS like it is recommended all over this site.
*update*
my gps works now
uninstalled HTC GPS tool
also took out blackberry connect software. it seemed to be lagging my phone in general

yeah I find this to be the fastest fix. I run gpstoday, open port for gps using gpstoolpro take the step to set up gpstoday once your fix is established I set up my gpstoday app to search every 5 minute rather then staying connected due to battery. When I am ready to use my gps I load up quickGPS have it a establish a fix( average of 15 sec I have been testing it for a week and have gotten good results instants fix to a 15 second wait).once I establish a fix I load up my navigation app. a tip is to be outside or near a window when trying to find a fix. Keeping the port open does not drain the battery.

Um im running the stock at&t rom on my fuze and my tilt (but the tilt is upgraded to 6.1 by att) but um you almost had it right the answer was in the forum but mixed into a few posts. Ok so when you go to google maps click menu then click Options then gps settings and go to manual then choose com : 4 then use 9600 and bam it works on both the tilt and the fuze with stock rom's.
