I have a Sirius Sportster and a 2004 Audi A4 that is pre-wired for satellite radio. (SAT button on the radio, wiring harness on the passenger side of the trunk.) Does anyone know of any aftermarket kits or adapters that would allow me to connect the Sportster to the existing wiring and control the unit with the in-dash radio? If not, is there a way to determine which wire in the Audi wiring harness is the car's satellite antenna so I don't have to use antenna from the Sirius car adapter kit, conceal the wiring, etc? Sirius technical support told me Audi sells an adapter kit, my Audi dealer does not know of anything like this.
Thanks!
Thanks!
