GPS Position jumps all over

mijenix · #1 (**permalink**) 02-21-2009, 02:51 PM

I have a stock xv6900, no custom roms. I have installed the Valhalla GPS cab with no problems and I have installed TomTom Nav6 as well as IGo8. The both work, but my GPS position jumps all over the place from Greenland, San Juan to Alaska. I am getting plenty of satellite coverage and WinMiniGPS shows that it is locked at my home coordiantes. I have even tried GPSGate to forward the GPS to the correct port and everything there seems to work fine, but my position never locks and keeps jumping all over. I have searched the forums, but have not gotten the correct answers to my problem. Any help on this matter would be greatly appreciated. Thanks.

Instead of using COM4 as the input port for GpsGate try to use "WM GPS". Hope this helps.

Thanks Steve, I have tried the changing the input on GPSGate to WMGPS and then put the output to Com Port 4, and Virtural Com Port 1&3, neither way works right. My GPS position still jumps all over. I can't figure out why WinMiniGPS shows my correct position, but when I start TomTom or IGo8, the position jumps all over.

I'm using iGuidance 3. Here's what I did:

1. Set GPSGate (2.6) input to WM GPS
2. Set GPSGate output to Virtual COM2 / (All NMEA) NMEA Filter
3. Configure iGuidance to use COM2 as GPS input with 4800 baud rate

You might try similar settings on TomTom or IGo8. Good luck.

I tried what you said, and now I can't get my GPS to pick up even one satellite. I have tried just about everything I can think of to get it back working, but nothing seems to work. GpsGate just says GPS data but no position and the icon stays yellow, it never turns grenn like it used too.

Stevens...Wow this solved my GPS problem. I could not get copilot live 7 to recognize the vahalla gps server. Everything else worked except my copilot program. With this GPSgate program it works now!
Thanks!!!

Sorry to hear that. I think you might have already tried these but here is something I can think of:

Make sure Location Setting is set to LOCATION ON
External GPS is set to COM4 and Manage GPS automatically is checked
Using external program such as Google Maps, MS Live Search or GPS Toggle to wake up the internal GPS
Sometimes a soft reset might help

Stevens,

I couldn't get the GPS to work at all. I ended up just re-flashing with the official verizon update to win6.1. My GPS is working now, and WinMiniGPS shows my position correctly, but TomTom and IGo8 still show me bouncing all over the world. I'm not sure what else to do.

Mijenix,

Did you use the latest version of GpsGate?
What GpsGate settings did you use, input, output?
What TomTom, IGo8 GPS port did you use?

I also found something in the TomTom site and don't know it heps: http://uk.support.tomtom.com/cgi-bin...i=&p_topview=1
