Well in his case, it looks like he simply plugged the satellite radio into his auxilary input. It's that wire that goes into the front of his head unit. That satellite radio looks like it's one of those universal units that you plug intp your aux. input if you have an aftermarket stereo, or use one of those crappy FM-modualtors if you have a factory stereo. If you have a satellite radio-ready head unit, you buy a tuner (a little box that you can hide anywhere) that works specifically with your brand head-unit and then you use the head-unit to control it.
