Here we have a good used oem navigation radio head unit removed from a 2005 Porsche Cayenne Turbo which sustained engine damage. These parts should fit all 03-06 Cayenne and may others with the same options/part number but will likely need programming to your vehicle. We are also parting out the rest of the car so If theres anything else in particular you need otherwise please send an email so I can list it on ebay for you.
