Wizzy, sorry completely disagree. I frequently play music dvd's in my other car and i take glimpses of the screen on occasions, its great at traffic lights.
The GPS in the Volvo is crap and I'm constantly looking at it, directions by voice do not help unless you look at the screen.
Yes it maybe illegal and so should a GPS be - maybe its just me but in the end I dont really care if its illegal or not. On another note, having tinted windows under 35% VLT is actually illegal in Australia(some states slightly lower) I wonder how privacy glass which is under 16% is then allowed. Privacy glass on Mercs and Some VW's are pitch black!
