I meant set gps to standalone.. flightmode would work, although I belive tomtom requires bluetooth to be on (odd quirk of tt)
here's the reg setting for standalone mode
Code:
[HKEY_LOCAL_MACHINE\SOFTWARE\HTC\SUPL AGPS]
"GPSMode"=dword:00000001
"EnableGPSSmartMode"=dword:00000000
"EnableAGPS"=dword:00000000
