Audio Systems: Sirius Radio and my new Head Unit, auxiliary input adapter, sirius system

Question
Hello,
I currently have Sirius radio and absolutely love it. I will be upgrading my stereo in my Jeep soon, and while I don't need anything fancy, I want something made to work with my Sirius system, but not with the FM RF tuner. I found a Sony unit that is 'Satellite ready', but they tell me I need to buy another $100 part in order to hook the unit up directly to the stereo. As I understand it, this would let me tune my Sirius stations directly thru the head unit, but I don't really care about that, since I like the Sirius tuner(Sportster 5). So I need this 'Sirius Connect' box if I don't want to control the Sirius receiver, or is there just an adapter that has RCA jacks that I can connect straight to a stereo like this?
Basically, I don't want my stereo limited anymore(can't get any regular radio broadcasts), so I WANT the stereo with the correct inputs, but I am perfectly fine tuning thru my Sirius receiver for the near future.

Thank You,
Mike Wells
