Hi i have an X5 2001 model. 3.0S but now it has develop a fault whereby the audio output can come on and go off when it wants to and sometiumes doesn't come on at all. There are no output from Radio, Tv and even the satnav. So i dunno what to do to fixed it. I hope that anyone can come to my rescue before i will have to buy a whole new unit set. thanks ben
