Rear Camera & Ipod control on screen.
I have a 2005 e53 x5 with the 16:9 sat nav screen, i want to install a rear view camera which i have seen around ebay ect, the ccd type, looks straightforward enough, the tricky bit being the routing of the cable to the front screen, ok so far..stay with me..but i also want to fit either an ice box (or similar) to have ipod, iphone, sd, hard drive control ect on the screen..questions are these..
1. how do i make sure i have enough inputs available to the screen when i fit these (i want to fit them both in one hit)
2. which is the best unit for the music integration?
3. what is the optimum route for getting wiring to the nav unit?
Any help or comments are much appreciated .
