I have a xda 2 and everytime I try to fire up Tom Tom it comes up with GPS unstable....nothing has changed GPS is mounted behind the screen in the same place. cant seem to get it to recieve a signal
I will mention that I have uninstalled the software and also the bluetooth GPRS & it descovered it quickly with no problems but it will not connect to tom tom or indeed give me a GPRS postition!
Another thing is it possible to search tom tom by postcodes only as it gets well stressed if you dont have all the details
If you get an unstable signal message try clicking to navigation mode, this will sometimes lock on whereas it will not lock on the opening screen. Did it work correctly before? If not it maybe you have a metallic windscreen that is blocking the signal.
reply
Sorry I have just updated the message....
As I say nothing has changed as regards the vechile ie its still used in my merc sprinter van and the wind screen is not an issue as its not been replaced......It was working fine till I installed a tom tom update from what I can remember
Have you tried clicking to navigation mode when you get the message, my xda 2 displays unstable signal until I do this, it then locks to my location and is fine afterwards.
reply
Yes I have the xda2 in the bedroom now with me and the gprs on the window sill......
In nav mode it says gps postition unreliable
found the problem in the gps settings it was setup as a serial port connection on com 1 not bluetooth!
thanks for the messages
I have HP ipaq 6915 Italian, WM5. I have updated the satellite data from quick gps connection. I go out, but the yellow gps icon never turns green. I use gpsgate 2.0 with Destinator PN. GPS is found, but myposition is never found, no matter how many satellites it locates (usually 5-7). What's wrong? Help!
Hi !

Thats because the GPS need constant signals for it to get the 3D position. It may required a long start before getting the position for first time start up, mine around 30 minutes, after that getting position will be a drift
some tips
Try standing on a large field or something with no buildings in near sight to get maximum signals
Dont move while getting the signals
Make sure that the weather is not cloudy
I really liked the trick with the registry and the gps icon. I can't try tom tom because there is no map available for my area. I use DestinatorPN and gpsgate 2.0. Still the same problem. No position. I haven't tried to stay out more than 15 min. I'll try 30 min or more tomorrow. I hope it works.
Hi !
Did you try go to START menu then SETTINGS then CONNECTIONS and here is the icon QUICK GPS CONNECTION, tap on this icon and then download the newest drivers for internal GPS. I try now the GPS connection and the weather is cloudy and i have got the connection in less than a minute !
Try this, maybe it will work.

I've downloaded the latest data with quick gps connection. It was the first thing to do. Nothing works. I'm desperate!
Hi again,
If you do the registry hack then you have an icon in your Start/setings/system folder is it wright. If so then you tap on GPS icon and set up your GPS. GPS "Programs" set to NONE, "Hardware" set to COM7 and baudrate set to 57600, "Access" untick the "Manage GPS automatically" thats mean you must disable this function. This is it. You can tray this last option.

Hi all,
I have encountered a strange problem on my IPAQ 6915.
I am using the IGo GPS spftware and it suddenly stopped detecting satellites.
The really weird thing is that when I set the IGO to find the GPS on com7 with 57600, the IGO program starts going haywire and it it looks like it is clashing with another program.
I have removed all the latest software I installed (mostly SPB utils) but that didn't help.
Another issue may be a registry cleanup I did with SK tools.
I am not sure how to solve this - any ideas?
Thanks in advance,
Danny.
Hi danab11 !
Did you try with Quick GPS Connection and download the newest satelite location files ? You can Try this. You just go to Start -> Settings -> Connection and there is an Icon with name: Quick GPS Connection -> click on that Icon and then press Button: Download Now (Before that Turn on your Wirelless internet connection that software can download this files)
Best Regards,

I think the problem us deeper then actually detecting satellites.
I think the problem us deeper then actually detecting satellites.
I think the IGO software is conflicting with another program.
The strange thing is that it only happens when I set the com port of IGO to 7 (which is the only correct port).
Any ideas?
Same here!
I'm having the same problem, anyone figure this out?
It just stopped detecting satellites, using TT6.
I'm pretty sure the following tip is accurate. I received yesterday a new HD, my first having broken just by pressing the screen! I was very relieved that just by reinstalling from memory card all my apps, that the apps settings were still valid - I didn't fancy having to go all through setting up tomtom again with pocketgps camera database and warning tones.
However I did notice that after switching Tomtom on, it was hit and miss whether my unit found any satellites. By going into the satellite status screen, I could see that the software would access the satellites for a few seconds then lose them again. I also noticed that a fix for this was to run google maps first and turn on gps from there.
This was strange, since my previous HD, locked on within seconds every time. Hardware issue? Maybe, but thought I'd try to remember anything I hadn't done on my new HD that I had on my old.
"Ha-Ha" I thought, I haven't run the connection wizard, and this is sort of a connection issue.
Start --> Settings ---> Connection ----> Connection Set Up-----> Tap O.K. ----> restart
Now TomTom works perfectly and picks up connections immediately without google map initiation.
Try it if you having similar troubles!
cheers,
mooro
For me this must be a placebo, neither do I understand why the connection setup has anything to do with the gps chipset, nor does it work me. I have configured my connection using the connection setup and nevertheless I have some gps drops with iGO.
I think this gps drops have some other background, I will try a new radio version. Some people also said that it might help to change the polling interval, but for me neither an increase nor a decrease of the interval has changed anything about it.
Not a placebo for me, is working perfectly now.

Nobody has said that placebos don't work, but the reason why they work is controversial. Maybe you have done something else, because I really can't imagine how the connection setup could fix a problem with the gps.
However, its good to know that it runs for you, maybe it will work for me with the new radio also.
How about this theory:
Because you did not do the connection setup yet, the GPS Quickstart had not run yet. So no almanac of GPS satelite data existed yet, meaning it was an icecold start?
And Google Maps worked faster because it is using the 'about' position of the GPS towers to bootstrap the location?
Placebo works only for those that believe in it!
This device is A-GPS capable.
Don't know whether e-plus supports A-GPS services but in theory this might be a clue
I have tried all of the above and still I cannot get GPS to work
If I open google maps it just keeps searching with indicayor showing no satellites.
When using TomTom it displays a number of satellites but all appear grey and none become active
Advice welcome

It may be too obvious to mention, but: Did you try this outside with a good sky view? Cold start is always a bit more tricky.

have you tried start ---> settings ----> external gps --->access---> check manage gps automatically?
and in google maps, options-->gps settings---> toggle auto/windows?
I am fairly sure intermittent gps is a memory problem of some sort. I used to get that a lot running IGO. Now I kill TouchFlo every time before running IGO, and even thought the problems still happens sometimes, it is clearly much less often. You can find the description of how to kill TouchFlo using Mort script in IGO thread. This makes the whole thing clearly better (not perfect).

Tried both of these.
Yes I can see that satellites are being picked up but both google maps and tomtom don't fix onto any of them. They all just appear grey
Maybe you should try a tool by htc to try and wakeup your gps. Run the file on your HD and from function menu select chip and then q7200. Choose port 4 and baud rate 4800. Then open the port and wait for a gps fix. After that close the port and exit the gps tool. Then run your gps navigator and see if it works!
Hi,
I had issues with GPS and tomtom 7.
I discovered that it was caused by a modification I did to the registry with HD Tweak.
Here is what I did:
going thru the settings with HD Tweak I seen that default value for AGPS was Disabled so I decided to set it to enabled it as I now the phone is capable of it.
After that The GPS would only work once with tomtom, if I closed tomtom and re open it again it GPS would not be found, I had to reboot the phone for it to work again (for an other single use).
I restored the AGPS value to Disable with HD Tweak and everything worked perfectly after.
Though I noticed that tomtom will still use AGPS when GPS sensor is down, but I can say if this is how it used to worked before the registery tweak because I did the tweak immediately after installing tomtom.
I had a similar problem with Advanced Config after I turned on Quick GPS Fix, turning it off seemed to fix it.

I don't think so. My "fix" (as I reported in another thread) is to change baudrate in IGO GPS configuration. After one or few baudrate change, the connection is stable.
No one as reported this fix not working.
So it seem a virtual COM port issue..

Yeah !!! Seems to work on my side !! I just spent minutes fighting with my HD this afternoon, still loosing the GPS device... I had to activate one other GPS app to make it work. Now I just changed this setting and it seems to work !!
Thanks for the info ! You're my king
Worked for me by turning off a-gps in HD Tweak and enabling it through the gps app on the rom.
after flashing the 1.10.25.25 radio on my HTC diamond, The GPS signal goes on and off, on and off....continuously on the TomTom GPS status. it was strange, I have to use QuickGPS to download the data again on open air to get the signal on continuously again. If I download the data inside my house, it just go on and off again when I use it on open air.
Hi
I use TomTom6 with my X1, and it did works fine before. Since a view days I didn't got any GPS-Signal at all. Is there anyone who can help?
Thanks for your help.
Regards, Richard
Simple things to try first:
1. Switch off/on
2. Download the latest QuickGPS file
3. Stand outside for several minutes with Tomtom running
Open up the GPS monitor in Tomtom and you should see the bars move up and down as it acquires satellites. If you see that, just be patient until the bars turn blue which means you have a lock. If you see no bars at all, and maybe a message saying 'No GPS', use the configure option to select the built-in receiver.
Had the same problem and even the new QuickGPS load did not work.
I installed the HTC GPS tool and searched for the Satelites with the "Clear Memory" option. Took a bit longer ~15 Min to get the fix, but now it works fine as well in TomTom
try to disable assisted gps
generally it don't work indoors really try outside
