XDA IIi with GPS

[doogan9]

Hi - I have put Tomtom on my IIi and have been using a bluetooth GPS receiver. This works OK for a while and then the screen locks up and I have to do a soft reset. Having reset it with the route again it will go for a while - maybe 30 - 40 miles (varies) then it locks up again. Any advice would be welcome. TIA Doogan.

How do I upgrade the ROM and the OS. I have purchased the unit in USA from T-Mobil
