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 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)

GPS Not Working

Just got my 8925 and cannot get the GPS to interface with TomTom. It keeps saying GPS connection not found. Is there something special to do to activate the GPS? I have run the QuickGPS.
Thanks in advance,
Tomy51

tried going outside?

Yes, I went outside, tried the 3 different types of GPS's TomTom has ans still not connection.

ok i run tomtom as well here is what i do:
1) download quickgps update
2) open gpsrouter com4 baud 4800 (search it if you don't have it)
3) run gpstest (under settings make sure it is at com4 baud 4800)
4) open tomtom (change preferences>show gps stutus>configure> try other NMEA set at com4 baud 4800 or Built-in GPS receiver. I tend to get a quicker fix using other NMEA)
good luck.

Thanks, that would probably explain why my gps isn't working as I do not have gpsrouter or gpstest. I'l go searching the forum to try and find it. Knew it had to be something, thanks agian for the help.

You really shouldn't (don't) need those things to make TomTom work. Just make sure TomTom is set to use the internal GPS (or set it to COM4 etc as above, depending on the version you have).
I use the TomTom that came on CD with the phone (not every carrier includes it) and it works perfectly, but you do need to be patient when you first start it up. Initially, it was always say "No GPS device!" for a good few moments before the internal GPS starts up, and then you'll get "Waiting for a valid GPS signal" - how long it waits then is down to your position etc. If you're outside with a good view of the sky - and your QuickGPS data is up to date - it could just be a few seconds - or you might be waiting forever if you're indoors/covered etc.
Does the "No GPS device!" message dissapear after a few moments for you? If it does then all is fine, you may just need to be more patient. If it doesn't, and it's constantly saying that, then something is misconfigured somewhere.

The ATT tilt US version doesn't come with tomtom. I have had a purchased tomtom and the cab that is floating around this forum. The only way i can get it to work with either version is to have gpstest and quickgps. But without gpsrouter i usually have to wait 10mins for a fix. Kinda sucks but hey at least it works now.

That's a real shame, because it works perfectly with the HTC rom. I wonder what AT&T have done to cripple it?
I just tried mine in the office and despite being inside (though on the top floor) it still had me located in about 30 seconds. There's a real joy in having a full-on, reliable TomTom in your phone - I recommend a ROM upgrade!

tomtom just sucks without support applications i guess. I have dutty's april 16th and i get a fix within 10-30 seconds now. Yes, I as well can get a fix from my basement within a minute if I have used my tomtom outdoors within the last quickgps upload.

Quick GPS question...

I have just updated my ROM to "Dutty's WM6.1 Hybrid v2 5.2.19716/5.2.19700" and at the same time installed TomTom.
It can take quite a while to pick up a lock the first time the software is booted but if I close and open TomTom without rebooting the phone the second time is much quicker (almost instant). I have just tried rebooting the phone and it goes through the same slow process the first time tomtom is booted and then quick following that. Is this normal behaviour for GPS on the device (not holding GPS info when the phone is rebooted) or is it an issue with the ROM or Radio. If its the radio is their anyone in the UK who can recommend the best radio for battery life and GPS.
Cheers,
Michael

This is pretty normal for GPS especially on these devices. It takes a while to get the first fix after a reset, but subsequent ones are quicker.
You may be able to speed up this process by using the QuickGPS tool to download cache data of satellite locations.
Also, try and use GPSTest to get the lock first. Many people use the GPSTest application and keep it running in the background as it tends to keep a good lock on things.

Adjust the baud rate with GPStest.

cheers for the responses... i will try the GPSTest thing...
KDKobes: what change does adjusting the baud rate make? quicker to lock?

I'm running the new, stock 6.1 Rom, and the only criticisim I have of it is the really slow initial GPS lock. The first time I use it after a soft reset or reboot, it can take anything in the region of 10-15 minutes, which I really don't think is right - I'm positive the original Rom was better at this. Subsequent fixes are much quicker, but if you find yourself needing the GPS and you happen to have recently rebooted, chance are you'll be well past your destination by the time it picks up, which is not good.
Quick GPS appears to be behaving as it always has - whenever I check it has recent data showing, downloaded through Activesync as normal - but it's almost as if that data's not being used in this Rom.
I should mention I'm seeing this behaviour in both Tom Tom and Live Search... it always does get a lock eventually, so there doesn't appear to be a problem with the GPS itself. Has anyone got any insight into this?

The baud rate is used by the internal COM port to interface with the GPS controller. It is the same deal like the speed of a modem...2400....4800...9600, etc.
Honestly with the amount of data that a GPS passes (which is not that much) I don't know if it makes a difference if it is set low. However, I always set mine high because faster is better, right so, might as well.

Where would you even set that though? I played with GPS Tool for a while, but it appeared to forget whatever port setting I used next time it ran anyway, so presumably it only affects that session of GPS Tool, not the system as a whole. In TomTom there's no speed setting for the internal GPS either; it should all be handled by WM itself.

Yeah, I think that's right... you can set it inside GPSTest.
However, like I stated many people find that GPSTest gets the quickest lock and prefer to either open it first and/or leave it running in the background. I haven't used my GPS that much, but I do find that this works.
It at least allows me to see what is going on with the lock. If I start Google Maps it will either work or not with GPS, but not really show me what's going on. GPSTest will allow me to see if I have a lock or not and then open up my other apps for use.

I just realised, I'm talking about the HTC GPS Tool, while you're talking about GPS Test - which is that, the Chartcross one?

You should try IGO8

Hello!
I have experienced exactly the same problem as you have with TomTom.
I have both a "Tytn II" and a HTC Advantage (X7500).
When using TomTom on the X7500 the GPS takes time to fix a position, 15-20 min or more is not unusual after a soft reset.
Then when it has fixed the position it is EXTREMLY slow when it comes to calculating the route!
I live in Sweden and I often drive to Germany, and when calculating the route from Sweden to Germany it takes over 3 min to finish!
Then we have the issue with the struggling graphics, (Of course I have been told that TomTom has trouble with VGA displays, and I find that to be very true.) the map is very slow and sometimes it stops completly for a few secounds!
On my Tytn II however the map is not struggling the same way, and it calculates much faster then on the X7500, Why? I dont know!
X7500 is a much faster device so it beats me!
The GPS lock is however almost as slow on the Tytn II as it is on the X7500, no matter if I have used quick GPS to download data or not!
A few weeks ago I stumbled upon a navigation program called IGO8, I decided to try it, and believe me when I say that I will never go back to TomTom again!
First of all the GPS lock is almost instant with IGO8, from a soft reset it finds a lock within maybe 2 min at most! And then it seems that it somehow remembers the position and the next time you start the program it will have a fix in secounds!
Then it calculates much faster, I tryed to calculate the route from Sweden to Germany on my X7500 and it was finishes under 20 secounds! (Compare that to over 3 minutes with TomTom on the same device!)
It supports VGA screens, so the map floats much better on my X7500.
Next thing is that there is more maps for IGO 8 so it covers much more of "mother earth" if you want to navigate in a foreign country!
It also has 3D terrain, and can even show buildings in 3D! (Only works in some places!)
It has a very simple and logical interface that is much easyer to understand then TomTom, and it is skinnable and very customizable!
So if you are serious about having a great navi I would strongly recommend you to try IGO 8! I can promise you will not be dissapointed!
Oh and buy the way, I dont work for IGO either!

I have problems getting software on my O2 Stellar to recognise the internal gps. I've tried a couple of different programs (TomTom & GPSTuner) and also fiddled around with the com ports in both the software and on the Stellar (using the External gps app in settings) but still no recognition of the internal gps.
I caleed O2 and no one could help, in fact they didn't even know it had internal gps!
I've seen GPSTest mentioned a few times. It's not on my Stellar - where can I get it?
Am I missing something?
Help please!

Get GPSTest here
You can either manually set it to a COM port or have it autoscan. I believe some ROMs identify it as COM3 and others COM4, so probably best to do an autoscan. It might take a few minutes to find it, and then another few to get a lock. But after that it generally starts up and locks within a minute or two (in my experience).

[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..

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.

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

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..

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.
