none, just walk
im after my first gps unit for my car, my friend has a tomtom go i think its called and i found it really handy coming back from london the other day he plugged his phone into it and it found a new route around a up coming traffic jam and worked out a new route, i would like something like that, it has to be touch screen and i wouldnt mind if it had the speed camera thing, any surgestions?
