Part two of my problems. The rear view camera seems to be a problem I don't care about now. I pulled the passenger plate off and there was a Mobridge bluetooth combo ABT2010. The fibre out was going to the PCM. But there was no other fibre cable hanging there. I took some of the back of the suv apart where the amp and the changer is and I can see the fibre installed in the amp but it looks like a loop is in a fibre behind the changer. Does anyone know the route of a fibre on the Cayenne? I want to remove the Mobridge. Oh and does anyone know how to remove the changer without tearing the suv down to pieces?

EDIT: Nevermind found it, didn't look hard enough. I removed the loop from the Mobridge and its all working. Still need to figure out the changer.
