GPS Fix Problems (official HTC ROM)

i have problems with Satalite FIX.
it can take mor then 10-20min (if at all) to get a fix.
i setup my GPS manualy to COM9 @ 4800.
i know (at least) one other user have a simular problem.
HTC, after some e-mails, say that if i DON'T use TomTom software, they can't help my with this isue.
any idea ?
thanks.

Fix
I had some problems with slow fix. I enabled the GPS applet in settings and it was configured at 33600, changed to 4800 and also in Tomtom and miomap settings configured to 4800, after that, very quick fix, on cold start less than 1 min, on warm start just seconds. Try it.

under, settings -> connection -> GPS ...
i set:
program tab:
GPS Program port = GPD9
hardware tab:
Port = com9
boud = 4800
access tab:
mark on the manage GPS Auto.
is taht OK ?
and allso on the navigation program i set manualy com9 @4800

Yep, that's my config and works right...

interesting... i have my settings as follows -
program tab:
GPS Program port = GPD1
hardware tab:
Port = com1
boud = 115200
access tab:
mark on the manage GPS Auto.
with these settings i get a fix in 30 sec to 90 sec...

After a sofreset? Probably not
The "warm reset time" in a GPS is not related with the Port number or the baud rates...but with its sensibility

SAme for me the GPS response can take up to 10 minutes.
I tried your setting Julioski and AriebK but it doesn't help?
In tomtom I don't see where to set the port and the baud speed can you help?
Any other ideas?

after configure the above settings, i get FIX, but after 20-30min of navigation... the FIX is gone, one more thing, i notice that my phone 3g signal drop allso, SR was nedded.

According to HTC the reason the GPS function was not enabled in the first place was a conflict with the GSM signal,anyway try manually setting your phone band to GSM and see if that makes a difference.(Settings,phone,band,select network type:GSM)

What radio version have you installed?
1.35, 1.38???

I have an HTC p3600 Trinity and have also just installed the newest ROM from HTC.
I downloaded the TomTom application from HTC, installed it and everything "seems" fine accept I cannot acquire any signals.
I have tried many of the different GPS settings from the GPS manager, but nowhere do I see a way to change what TomTom is looking for. There are 5 default gps reciever options... (builtin, bluetooth, wired, other bluetooth and other NMEA device) and I really have no idea what to choose if I have to input the settings.
Can anyone help?
Thanks!

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

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

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

Maybe that's why ... sorry couldn't help it...
Are you sure there aren't any other factors involved (like heavy cloud cover, rain, , etc.?) or more than 3 days since last fix (not that this should take 15 minutes - this is more than downloading the whole almanach). Can you check if you have signal all the time, or if you keep loosing all satellite signal? Because if it looses all satellites, he has to start from the beginning with the fix, so it's in a loop until he gets proper signal.

Well there seem to be quite a few issues with the GPS,personally i'm using the Destinator 6 software ,and here is what i noticed ;
With the official HTC rom :
The software detects the GPS in about a minute and acquires a fix in about 3-4 minutes with the GSM on and a clear sky.
If i softreset the device then 1/3 times it won't find a GPS antenna and i have to manually reconnect and define the com port,it then takes apprx 5 minutes to get a fix.
The weird thing is that when i used Destinator PN i didn't have any of these issues .
Lately i've started using img-32424-mUn and i've noticed a definite improvement in both GPS strength and speed.

i did use following test rom, the gps response is around 1min.
RUU_Trinity_CHT_1.23.751.1_101_6275_1.29.00.11_108_Test.exe
however, by using offical rom whatever config the baud rate or GDP, required 8-10 to get the fix.

the problem is that it's not stable
one day i get a FIX within 1 min, next day after 20...
and 2 days later, not getting any FIX.
i tryed with GSM and 3g ...
i guess the radio (or the GPS part) isn't as we excpect it
sad that HTC dont want to support users that NOT use TomTom.

I think it would be useful if each of us told the others the type of GPS software they were using as it (The GPS software)seems to affect the time it takes to acquire a signal.
Also try using the GPS with and without the radio (Flight mode) and see if it makes a difference.

No GPS Signal & Icon
Hi! I've another problem. I've downloaded new ROM upgrade and Tomtom applications. After waiting for 10 minutes, my device says no signal received. I read from some forums we can adjust some variables but there is no GPS icon under settings\connections folder.
Can anybody help me! I have version WWE 1.23.405.

GPS not being detected by GPS Test and GPS Viewer

Hi guys,
After a few weeks of very limited usage of my Tilt GPS, one day I noted that any application was able to detect the GPS. After reading other posts I noted that the solution could be a hard-reset, which I did, however, even after trying several hard-resets and different radios and roms, my GPS is not being detected by GPS Test and GPS Viewer. However, I noted that when I select COM4 at 4800 kbps (disable scan and select a specific port), the GPS led flashes but I never get the GPS starting message (just a detecting GPS message). Any idea what could be wrong?... can the GPS be blocked or deactivated somehow?...
Any help would be appreciated!... Thanks!

couple things to make sure before returning your phone. When using HTC GPS tool, go into the satelite section and see if you at least picking up 1 satelite. Verify you are not inside a building and you are outside and you are giving it some time. Flash another rom and do these procedures again. If none of these work, then probably could be the phone. Good luck.

You need to be outside to get a satellite fix. It is almost impossible to get a satellite fix indoors. You also need QuickGPS (freeware) which updates the ephermeris info and lasts 6 days. This makes a satellite fix much quicker. Try that.

GPS antenna
The UART baud rate of the GPS port should be set on 57600. Probably the communication can be done at 4800 like the SIRF chinese module but try to put the correct baud rate and see if the handshake works more fast.
Since I use the phone mostly mobile in my car, I just got one antenna from this eBay seller.
This one have full 15 feet cable so I was able to clip on trunk cover, near the rear window. The antenna connector must be fully inserted in the phone enabling the path contact and at the first insertion you need to apply more force (as usual ).
The phone will sense the current flow by feeding the antenna LNA chip so there is no such thing of mechanical device to switch antennas (internal/external).
The sattelite signal almost double and sometimes up to 10 sats can easily be locked and fast.

GPS working again!!!!.... but how????
Guys,
I'm posting as just noticed something really weird, and to be honest I can not find why the GPS is working again. In my first post as I stated, the GPS was working fine (I have an unlocked tilt with HTC ROM). Then somehow, one day the GPS did not worked anymore (I used HTC GPS Tool, and as soon I opened the port, I did not got any messages at all, it just hang! and with GPS Test the GPS was never detected! - in both cases the GPS led flashed!). Now, after giving up with hard resets, going back to the original ROM, updating QuickGPS data, etc. just yesterday, when I on was meeting playing around went to GPS Test and voila GPS was detected again!!!!... and so far is working fine... I have no clue what fixed it! and, I'm wondering if it may had something to do with my carrier... any one has faced something similar?... any idea what happened?...

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

[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.

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.

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.

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.

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.

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.
