Is there a way to get satellite radio to play through my existing head unit? It is the double DIN Symphony and not the Bose. There is not Sat. button on the radio. Right now I have a Roady 2 connected to an adapter behind the head unit, which allows the Roady 2 to play through the head unit when the CDC button is pressed. I would like to get rid of the Roady 2, and just have the satellite radio play through the head unit (and display song/artist info if possible). I have read some interesting articles on the web, but I am not experienced enough to know if I can do it with my vehicle, which is a 2000 A6 2.7T. Thanks!
