Can anyone please help me with which pin is for what on my 04 Cayenne? We have one audio guy in town and twice I've made an appointment to see him and both times he hadn't opened his shop. I want to go ahead and install my aftermarket radio myself. I don't know where to start for power, reverse signal, gps , antenna, or anything. Thanks.

 

Thanks in advance

 

This is a lot more complicated than it seems on the surface - especially with the fiber optic cables. How do you plan on interfacing with the rest of the audio system? What audio system came spec'd in your Cayenne?

 

+1 on that plus do you have the Bose system navigation etc? that will depend on wiring if you have the bose system you must use an interface to bypass that for the new stereo since they come amplified

 

Thanks for the reply. I do have the fiber lines and have them plugged into the adaptor that came with the wiring harness I bought. Where I am now is trying to match the wires in the car (ignition power, reverse signal, etc) to the documentation that came with the wiring harness. I have the diagram for the steering wheel adapter by Axxess and now just need to know which wire is power and such.

 

Off to renntech, I guess

 

Sorry, I do not have any wiring diagrams available for your specific year model. However, if you have access to a mechanic with a subscription to AllData, they can get you the wiring diagram you need.
