E53 Factory X5 GPS upgrade
I have a 2001 X5 with the Factory tape deck up front and the 6 disk changer in the rear hatch. I am looking to buy the factory GPS unit out of a 2001 X5. All it comes with is the Lcd screen that has a tape deck attached to it, 6 disc changer for the back and then the Gps cd drive (looks like a computer cd drive) would this be a simple swap over? Would I need additional wiring?
