Hi im about to buy my 2003 Z4 it has sat nav and phone preparation but a non multi function steering wheel, buttons for radio telephone etc, Can this be replaced by a multi function version if so what would be needed to do a job like this.
Thanks
Sorry to hi jack the thread I was told that 03 plate cars don't have wiring and the complex diagrams put me off of trying to fit it. Any clues as to whether I read this wrong before, I am dyslexic after all
