Second gen Sirius retention
I'm looking into getting an aftermarket head unit for my 2nd gen. I love my Sirius radio, and I want to keep it. I know that I need to get a separate Sirius tuner and the adapter to interface with the head unit. I remember reading somewhere that the stock Sirius goes through the stock antenna, is this possible to do with the aftermarket tuner as well? Does anyone know if it is a separate antenna plug that gets plugged into the stock head unit, and can I just plug that into the aftermarket tuner?
Thanks guys (and gals)!
