GPS Position jumps all over

[mijenix]

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.
