thanks for ap4 havent had a problem but i have gone and found so many settings for gps can any one give me a default or a list to have my gps work thanks
Theres a lot of advice here about getting a decent fix. The bottom line is your best bet is to use the physical GPS COM port unless you need to run more than one GPS app simultaneously . A software port cannot be more efficient than the hardware port unless it is opened regularly in the background to maintain a current fix.
The hardware is COM5 and Baud can be left at the NMEA standard of 4800.
Remember to go outside for a 1st fix
I had the GPS working and then upgraded to the latest DCD.
I now have:
DCD 3.2.5
Radio 3.42.50
I have COM port set to 4, hardware port set to none and baud rate 4800 and let windows manage the gps. I also set it from 911 to location in phone settings.
None of my apps (GoogleMaps, TomTom) recognize it. And GPS Viewer bombs when I try to open COM4.
Any ideas? I really need my gps back.
I remember some people saying to briefly flip Location back and forth from 911 to Location On a few times, and having it work. Try that, and maybe grab the HTC GPS Tool to try and diagnose this.
Also, if you haven't already, you may want to do the GPS fix that involves messing with QPST.
Hmm, I've got 3.2.5 with the .50 radio, and using TomTom 7 fine...so don't downgrade, keep working at it, since I have that same setup and working fine.
You might try the radio rom again. I also hear that *22899 might help. There are some other GPS software out there that will show you the NMEA messages, see if you are getting any and if not then your GPS is not turning on or there isn't a GPS chip in that phone. Just kidding.
I just upgraded to the latest dcd rom .6 from and older one. I didn't touch vereizon's.
When trying to configure the gps, I set th GPS hardware port to com 4, baud rate 4800 and the program port to none.
After I save and see that google maps cant find th gps hardware, I go back to the win mobile gps hardware settings to see that it switched back to none.
The gps was working fine before I upgraded the rom.
What am I doing wrong?
Did you read this?

Its a basic step by step to ensure you have all the little things done right.
I always forget to check to see if gps is set to on or location only.
help me with this
I onlty have rom 2.09.605.8, where do i go now?
Hi Mods!
I really sorry that I have to open new thread, because I and some others also posted here
http://forum.xda-developers.com/showthread.php?t=405016&page=4
but it seems that no one can solve that problem correctly. And MODs seems that don't know about that problem.
So, could MODs give us some ideas and solutions.
For example: I used Original ROM, GPS with TT7 was OK.
But when I change to another ROM (any other ROM), it was so good that everything works well but not GPS.
Hope to hear from u soon.
Thank you.

You do know about the problem with validating maps for a new installation of TT7 ?
Do a google for this in xda -devs.
i used this TT7 on Kaiser and it worked like a champ.
and from your instruction, I also sink to another sea that the need information is somewhere but could not find out.
could u pls give me a better ideas. pls don't tell me that: google something in somewhere.
I spent so much time to discuss and post somewhere else.
thanks
Clarify.
Please explain the type of gps problems your having, Problems with getting fixes? Problems with tomtom?
I need yr help
thanks friend
My problem is here.
When I bought x7501, I installed TT7.45 with Map of North America. It work fast and better than Kaiser I had.
Then I tried to Up ROM to SPL 3.5 (every ROM for 3.5) and I could not use GPS. TT7 work but it only show the working screen with: Waiting for valid GPS signal... forever. And when I find the GPS position, it says: Poor signal.
I tried to change Radio version but failed.
I also tried to convert back to SPL 1.2 now and working with Official ROM 6.0 (but with SPL 1.2 Oliprof). I tried to change Radio version, from 1.47 to 1.57 to 1.58 but failed. So strange (because I had to format the drive when I convert back from SPL 3.5 to SPL 1.2 so I lost my backup file for SPL 1.2 for original ROM).
Now I can not receive GPS signal.
I also try to install GPS Proxy,but this program doesnt run in my Athena, it says: Negative exception and quit.
I aslo try to change th port for GPS to another COM port, but it will not turn on GPS device.
In my Athena, the default COM port for GPS is COM4.
So, that's my problem.
Could you help me with detail instruction.
So thanks and wait for your help
try
you can try going to
settings/system/external gps/
*
software port com 4,hardware leave it at none,set baud 9600,manage gps automatically checked

load up ttn,click where u see signal bars in lower right,then agn on right above version number,configure gps to use other nmea,set com port 4,baud 9600
*
it should instantly have fix!
thanks friend
i hope it will work
i try it now then tell u later
but do u mean that it works for AP 4 only? or another rom?
What Radio do you have installed
i am confused because your sig says you have radio 1.57 but you say in your post above that you couldn't upgrade from radio 1.47.
AP4 needs at least radio 1.50 according to here http://www.htc-hackers.com/uploads/AP4_How_To_1.8.pdf

Steps are optimal for michy roms,ap4 gps should be blistering fast "out the box"! When I used ap4 I was using radio 1.57,and even indoors I had gps fixes in 30 secs after soft resetting.
As of now I use radio 1.58 for hsupa on michy 6.1 rom and have fairly good gps.The steps above emulate my settings with exception of rom.
GOOD NEWS - GPS is working like a rabbit
Hi friends
Firstly, so thanks to all of my new friends, who were trying to reply and show me the way to solve the problems.
Secondly, I want to give u the good news. Now GPS is working as a champ.
But it is a little bit difference with some guides from u.
- I follow the steps above and change the baudrate to 9600, but after reset, it comes back to 4800 as default.
- The COMPORT for program is COM 4. For the hardware, I set default is NONE.
- Then, I install VisualGPS.BeeLineGPS.v1.83.Build.125 and reset. After that I run Visual GPS Beeline first, it works after 20 seconds and lock my location when I stay in my car (The weather now is -1 celcius degree outside - very cold).
- Then I run TOMTOM, I choose BUILT IN GPS (but not other NMEA). And TOMTOM works perfectly after 10 seconds - I did that because I remember that I always chose BUILT IN GPS when I used TT7 with this one two weeks ago.
And here are some tests after that:
- I turn on Wifi, open DATA connection (that is a issue when I use Kaiser, if Data connection is opening, TT7 can not receive the signal), then open TT7 (without openning the VISUAL GPS), it works after 12 seconds.
- I come into my room (the second floor in a three floors house) and turn on TT7 without using any other software, it lock after 10 seconds with average 5-8 sats.
WOW. It can't be better.
But I still don't know which one help which one. Because, when I installed TT7, then I run it for the first time yesterday, it said: could not run because of the memory available.
Then I try to run GoogleMap (even if I did not connect to Wifi - so ofcourse GoogleMap only turned on but did not run with data), then I tried to open TT7 again and it run (confuse here, who can explain to me)
The problem only now is.... WIFI. I hope can fix it soon as the instructions from CMONEX.
Thanks friends.
slight correction
just a minor correction to guide after you stating baud rate returning to 4800, in external gps settings on hardware tab to change baud I notice you need to set hardware com port to com 5 first then setting baud to 9600 ,then click ok to save.Go back in external gps settings and back to hardware tab ,as you will notice settings saved but now this time select none in hardware port and leave baud at 9600 then hit ok.
As I remember in ap4 4800 baud was default and worked best with that rom anyway,and so far it works for you.I do recommend setting use other nmea in tomtom input your baud and software com port settings from external gps control panel because you used visualgps to boot up your gps to get sat fixes for tomtom, with these settings you dont have to use visualgps to warm it up.Make sure you update your quickgps evrey 2 days then soft reset and hold phone by window or go outside when you use gps with new emphemeris file from quickgps as it can take a lil bit longer to regain track ironically ,but once you get fix itll be super quick no matter where you are,even if you soft reset.The only time you need to have clear view of sky again to get sat fix is if you turn off device completely for an hour or 2, or update quickgps data agn in 2 days (up to full 3 sometimes) or flash a new rom :>.
For wifi,I dont kno how to fix,cmonex prob has to send you a special file to regain mac address so wifi can work even after spl changes.
Hi
Seem to be havin a great deal of problems getting the GPS to start in programs, like TOMTOM and google maps. I have installed and tried gpsplex and gps gate. and have had some connection success then nothing.
What are the best settings to have the com port on or none or gpd etc.
When updating gps position it will do sometimes then it says failed to save then it does sometimes.
Getting tired of this phone and weakening for the nexus one or back to apple.
search the forum you will find it.

Set com port 4 in External gps,then set gpsgate. Enter Intenal gps and download(check your internet connection if on , if not, try once again,if still no positive result , soft-reset,try again.) After getting gps-data, power on gpsgate, check for incoming data(OK),power on tomtom, get in open air until you got a gps-fix(depending on certain factors it can take a while 2-3 minutes), everything should be fine.
Let me know your progress(or not).
Hi
Thanks for the reply, ended up doing a fresh install of everything and after boot gps worked first time with google maps with gps on default setting of GPD9 in external gps setting, did the internal gps update over wireless lan as it seemed to work better than cell connection.
Installed GPSMod driver and bingo tomtom found it and everything ok.
But later after a few active sync sessions i went outside and again nothing off both google and tomtom, no sats found. Did a power down and again everything seemed to work, strange !!!. So that where im at, a not to reliable gps connection.

I was really frustrated with gps disconnections at first, was the only thing that bothered me in this phone, other than that i loved it. The problem is clearly a matter of rom's radio. When i had a rom with radio version 5005.1600.05 i had disconnection in GSM phone mode but steady signal and no disconnections in HSDPA mode. Problem fixed in 3G/HSDPA mode. Since i flased a rom with radio version 5005.1700.05 i had never gps disconnection problems in both GSM/3G mode. Problem gone!
If you have the stock rom installed, try turning the phone to 3G/HSDPA mode if it's in GSM and check again. But i advise you to install a rom with 5005.1600.05 radio version, great call sound quality and great satelite connection. I personaly found this rom Revamped Release 5 Loaded Radio 5005.1700.05 05/21/2010 best for me and will stick with it for a while.
The phone is ok, this is not a hardware issue it's clearly a matter of radio driver. Don't quit on this phone yet, it's a great device if you can cope with charging every day . But this is the case more or less with big screen-1ghz-small capacity battery phones, except if they have led screen
