but I just don't understand how you're doing it. I have a 2002 A4 w/symphony II and Bose. I saw the pictures that Proxus put up and my question is did he have to make the plugs and put the wires in for Sirius satellite to work. My car obviously isn't prewired for it. Do I need to get the adapter w/Bose,w/telephone,w/CD changer or do I need to just make sure it has the bose adapter? I'll never use the phone option but I'll likely try to do the DVD thing later. The general install of the radio is easy but the satellite part is what I'm not understanding. Thanks in advance.
