I have spoke to Vaheh at crevier my local dealer and he can supply most of the stuff but suggests that I source the screen and computer from elswhere due to cost.
Because I have an 05 with the BT and BMW assist that uses the GPS system I was hoping that would make the retro-fit a little easier and cheaper !!!!.

Thanx
