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.
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!
More GPS Woes

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!
Thanks

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).
Hi there,
It's indeed confirmed now that the gps chipset in diamond is Static navigation enabled, i.e. it won't refresh your location and speed if you are walking, it'll just lock your last gps location instead of updating it continuously while you walk. So it's nearly makes it impossible to walk to your destination i.e. you can't geocache at all.
I hope anybody has some clue about turning it off.
Have you tried something like SirfTech - if you can get it to connect to the internal GPS device (and assuming it is a SirfStar chipset, which I still don't know for sure?) then you should be able to toggle the static navigation setting. There are instructions right at the very bottom of that page on how to adjust the static navigation setting.
The other remaining question is how long this change will persist - hopefully it should persist until the battery is removed, but it depends how the power to the GPS receiver is switched - it's possible that switching off the PDA, or even putting it into standby, could cause the GPS receiver state to reset to default.
Its not a sirf chipset and those tools wont work on it

I second that. I guess we people will have to live with it. There's a HTC GPS utility from HTC which works on this qualcomm chip but I am no expert if there's any setting which can turn static navigation off. For someone wanna give a try to the HTC tool, download the attached file.
i just did a quick test with Diamond running TomTom walking along the street. It works fine in pedestrian mode. My actual postion was accurate at all times during the test. Diamond GPS is suitable for navigation in pedestrian mode.
Probably you have not tryed with some device with really good SirfStar III GPS, like ETEN X500.
@panosha
my point is: walking navigation mode is indeed available with Diamond running TomTom. I am not to compare GPS performance of Diamond directly with Sirf III equipped devices.
That said, if you take a look at my signature, you would certainly notice that I have also few HTC Sirf III equipped phones presently and not to mention TomTom GO 510. I am quite certain that Diamond is quite usable for walking routes..
Is usable for walking routes, but it has mediocre behavior for this use, concerning the good GPS devices.
@panosha.
mediocre behavior indeed.
I was referring to the very first post in this thread:
.. it won't refresh your location and speed if you are walking, it'll just lock your last gps location instead of updating it continuously while you walk. So it's nearly makes it impossible to walk to your destination i.e. you can't geocache at all...
Click to expand...

yes, it will refresh GPS location as you walk.
yes, it will update GPS position fairly constantly.
yes, it is possible to walk to a destination and geocache.
Sorry but I have to disagree.
While the Diamond keeps up with a standalone device while driving, I took them both out walking today and the Diamond is terrible while walking. In fact I did the route three times and it was always approximately 30 feet out of synch which is no good at all in a city environment.
If anyone has any idea how to improve this I'd certainly be happy to hear it.
I have a P1i and external receiver and at this rate I may have to return the Diamond and go back to it, which is a shame.
Yeah. That's the point. It indeed keeps up while driving but crap while walking.
Folks, I think it would be really important to find a solution for this problem.
It seems that it has definitely to do with static navigation and
is no problem of any kind of application.
Since I have my diamond I used a lot of different gps software,
but the lag is always the same.
This is indeed very bad, thus the reception quality is superb!
My last HTC was a trinity which had also a Qualcom chipset,
but with this device I never noticed such a behavior.
Somehow it must be possible to turn the static navigation of...
Are there any news so far?
I guess nobody could figure it out yet. WE have to keep our fingers crossed
Is there any other news?
Disabling static navigation would be greate!!
Does anyone know the brand/model of the gps chip?
And there's always a lag between your actual position and the position shown in the GPS software....
Sometimes this lag is more than 50m...
HastaSSSS
I am trying to see if the Qualcomm ONEgps - GPS can have its programming changed with QPST, but unfortunately I havent found any information on getting it to run with Diamond. I think that would be the only way to turn off static nav, as the system is not Sifir or what ever its called, so non of the current "static nav" off solutions will work. I have OziExplorer running and I get the issue. I also noticed that there is a lot of unecessary activiting on decent/assend info, its as though it has quite a unstable 3d lock.
Can anyone else using TomTom pedestrian mode could confirm if there is no delay (more then 10-30 seconds) between starting walking and position beginning to update?
Thanks!
D.
does tt has special option for pedestrian? maybe the problem is tt and NOT the hardware (gps-diamond)??
i am using igo and it has special options for pedestrian, for car, bicycle, public transportation and even emergency vehicle. seeing this made me think that the program will react different at different speeds.
i did not tried the pedestrian option but i promise to do it and come back with the results.
Sorry about the dumb question, bust how can I switch to pedestrian mode in TomTom???
It's the same s*ht
The GPS on this receiver, for the time being, really sucks...
I'm hopping that someone will figure out a solution, or with a release of a new radio ROM.
Even when I'm driving, the gps lags so much.... Drives me crazy!
When I stop on a red light, the gps still indicates speed for 15s more or less, until it actually stops on the place where my car actually is...
I wonder if the gou acceleration driver is actually installed...it could happen that this delay is due to the fact that the CPU has to do all the work, and since the resolution is VGA, it means extra work, which the CPU can't handle 100%...
HastaSSSS
Hi everyone
I have spent a lots of hours searching for the answer to bad gps reception on diamond, through different forums.I was about to sell the diamond when I finally came with a solution and that is Hard Reset after each Rom flashing.
For a few days I could not get a gps fix, no matter what I did. I tried Quick gps, Gps tool , Google map, iGo8 and Garmin. Somewhere I read that it could be the Rom I am using. So today I flashed 4 different roms including Dutty's, bepe and panosha but no gps fix. Finally I did a Hard reset and viola, it found the satellites within 10 seconds inside near the window on all the different Gps softwares without any problem.
So here is the procedure:
***After a ROM flash finish the usual soft reset and stuff and then do a HARD RESET. Download the data through Quick Gps and your gps should work properly at its default settings.***
Actually I found that Diamond is faster than TYTNII for getting the Gps fix.
Now if the Cooks can find out what causes this behaviour so we do not have to do a hard reset after every new flash.
Please share the findings.
Cheers!!!
********* Ok I have been flashing all the new roms and Gps was not working even with the hard reset. Finally I flashed CT's Beta lite2 Rom, did a hard reset and viola Gps is working flawlessly for the last three days. This Rom is actually the fastest and very clean among all the other roms I tried ( no offence to all the other great Cooks ). Please try it and share your findings!
Well, now i know why i dun have GPS problems...
i hard-reset after each flash ... just a habit inherited while using artemis...
Hi, nice tip
When you had done a hard reset, is the GPS working fine after several reboot ?
It will be nice if someone on XDA or HTC find a solution
Yes its working fine since then and I have done several soft resets.
Fine here. The only thing that made the GPS not work for me was turning on A-GPS.
Doesn't work for me. I have changed my ROM to bElite 0.93, have done a hard reset, loaded quickgps data and still no fix after half an hour on the window.
Try going outside in the clear. If you get the fix then its the location of your window.
try using HTC GPS Tool, it fixed for me once:
http://forum.xda-developers.com/showthread.php?t=360477
install the cab, run it, then choose "Cold Start" let it run for awhile then try using your GPS software again.

HI, ... Hard Reset,- you mean reformatting the internal storage as well? - i've done hard reset but still the gps can't fix location- says in HTC GPS tool - Mode 2: Not Fix
thanks
Mode 2: Not fix...
And the sattelites numbers show just #? Or u can see actual sattelite numbers?
Reason I'm asking is, if you just see #... then ur GPS is scr###d up and the cold start could really help.
If you do see the actual numbers, but no reception bars, then you have to get ourside into the clear sky. Be aware that nowadays windows are protective for keeping the heat of the sun outside. At the same time it keeps GPS for 95% out too.

You haven't been playing around with the GPS settings in the configuration of 'external GPS'? The standard settings are: GPS program port COM4 / Hardware port = none with a baud of 4800. Access tab should have GPS set to be managed automatically. Also, you have not enabled AGPS in any way like with a registry key or the advanced config program?

solution for fix not vaible
the gps is broken ?
My problem is not the fix, but rather the lag and lack of precision while navigating...
I have more or less 5 seconds of lag, and the precision is awful...
If I use a BT external receiver connected to Diamond, than I don't have this problem...
It seems that the receiver is refreshing to less, or the communication between the receiver and the GPS software is too slow...

I just tried to force change the gps port from settings>external gps from port 4 to port 6 and in my tomtom, i choose other receiver then tap port 6,was showing poor signal- i minimized tomtom, opened htc gps tool opened port 4 at 4800 cold start> gives me error message that the port is closed and it will force open nmea but still fail, in this part i tapped nav init.. then closed it- opened port 6 in cold start> showing all sat in #### instead of numbers. then closed it. then go to settings>external gps> then choose port 4, opened tomtom then went to gps configure and now change it to built in gps... i get full 3d 6 green bars indoor. all ok even after a hard reset. Thanks
Yeah...but how to solve the lag and accuracy issues...?...

So far i dont have accuracy issue. i tried igo8 using bt receiver (SiRF III) compared it to the internal gps- it's just the same , internal gps loads even faster- In TomTom7- if i use bt receiver, some voice instructions is not complete unlike the internal gps which is flawless- maybe it's the rom/radio...
I don't have any problem
"Bonjour" (since I am french !!! )
I tried the GPS with TomTOM V7 = no problem
with garmin XT no pb
First idea
Within the programm window I have a "fast GPS" programme
Do you have this ?
Did you run it ?
Second idea
You should enable Agps in advanced config
On my diamond if I disable it doesn't work anymore
Third idea
Try to see if "GPS utilities" works
Google it it's a basic cab file for showing basic GPS (position, speed, elevation.... )
Let me know
Diamond FrencH Rom 1.37.406.1 FRE
i have the original rom (1.35.401 ) and radio (0.93.25) and igo 8 installed and i have a big gps lag (5 sec). Is it a problem of igo 8 or rom/radio? If i flash a newer versions it will help? Slould be a cooked one or original is enough?
This GPS lag problem has not yet been resolved by anyone. Let's hope some rom cooker are able to resolve this lag problem. There are apparantly many people sufferring from this
Hi guys,
You probably used ACT and enabled A-GPS.
You should disabled it.

Nope, thats not the issue.
A-GPS is disabled.
In my opinion the issue is generated by the interval between 2 consecutive positioning readings. It seems that somehow, the application doesn't receive data's from GPS fast enough and because of that, between 2 consecutive readings, you allready made 20-30 meters - enough to miss a crossroad . For example, because i also have a builtin car GPS, it seems that the IGO is allways ~20-50 meters (depending of speed) behind the builtin car gps
There are 3 options which can generate this issue:
1. IGO himself
2. Windows driver
3. GPS HW
For 1st option - i will try with a bluetooth GPS. Unfortunatelly i don't have one. Maybe somebody can try and let me know if the lag is the same?
Also if somebody can try tomtom (there are no available maps where i live) and let us know if still has that lag
For 2nd options - There is an option in registry called POLL interval which is by default 1000. I will try to set it to 300 to see if there is any difference. If is not maybe the dll has something hardcoded about polling interval
For 3rd option maybe with another Radio version the problem can be solved
Please let me know if somebody allready tried some of the options or have another ideeas
Hi there, I have GPS in my Parrot hands-free and it has the same lag as the bulit in GPS.
Seems strange that the Parrot has 2 times stronger signal (and about 2 sattelistes more) than Diamond And it even has not SIRF III chip!
So it is not 1)
Using TTN 7.45 and no lag

it's not 3) then - if you have the same lag can be related to IGO himself. So it remains 1) and 2)
possible solution?!?
I have / had the same Problem.
It could be possible, that several programs try to use the GPS-chip at the same time. In that case, it could be that windows switches the availability between these apps. At my Diamond this strange behaviour starts after taking some fotos. So infer from it, that the option of "GPS-Photo" could be the villain.
I switched it off with "advanced config" before one hour. And till now everything is ok. I hope it will last a while.
but on mine the GPS photo is allready disabled and it was never enabled
AGPS
Yes, i think i was wrong. Today in the morning i had the same problem, again. So i tried something else.
Disable the "Assisted GPS" seems to work. Since then i had no more problems today. Lets hold the thumbs!
i've tried another ROM and RADIO - the same issue
I can only say that you shouldn't expect no lags in GPS software. I was using a lot of standalone GPS devices like TomTom Go/One etc. and even they lag a bit even though they use SirfStar III chipset. You just have to get used to it. Of course, new ROMs may decrease the problem a bit, but don't expect it to disappear completely.
I used mine with an external gps receiver (Sirf III), via bluetooth, and no noticable lag was detetcted during more than 800km (from Bavaria to Paris)...
So, there is something wrong...
I just don't know what....
My next test, will be a clean install of the rom, and drive imediatly after. I wonder if any of the tweaks we apply have any direct or indirect interference with GPS ...

I am just saying what I can observe with other devices. I've got Go920 and my friend Go520 and we can both see a noticeable lag, the same with older tomtoms we got in our company. Of course it's much less noticeable than the one in TyTN II or Diamond, when I can clearly see that I've already passed the junction 200m ago and I'm still approaching it in my GPS soft.
I called HTC support Australia and informed them off its fault with GPS lag and its accuracy, I informed them that over 50% of users are having this issue on the XDA forum, they told me that no fault has been logged and there isn't an issue, It may be time to call up the tech support and make some noise to get this issue resolved. its a pain in the arse and it shouldn't be happening.
Maybe we should have a poll to get some hard stats on just how many people are experiencing this problem and add momentum to finding solution.
i just made a 1800 km trip and now i can say that in the city the lag of the GPS make it unusable
Maybe we can try to install igo2006 to see if there is any difference
I haven't had any lag problems at all, the only problem is the time it takes to initially get the satellite data.
Lag time iGO 8
I also experienced the lag time issue. However, it is really lag time as iGO8 seems consistently 20 m behind. Try to stop sufficiently long in an intersection and monitor what happens - my GPS wil slowly count down from about 25 m to about 20 m. In other words its consistently 20 m behind - the lag time is only equvivalent to some 5 m. One thing which seems to improve things is to alter the seting "re-establish lock-to-position" (translation from the Danish menu) and put it at 5 sec. Surely I have not experienced any such issue with my Blaupunkt and Mio A701 systems. And yes it makes it absolutely hopeless in bigger cities if you don't know the road.
