I don't know the specific model numbers off hand, but you can get a proprietary xm tuner that stays in your car permanently and can be controlled from the head unit itself. Or you can buy an aux-in adaptor and hook up a plug and play XM radio-but the plug and play will have to be controlled from the unit itself. The plug and play is usually the best way to go from my experience with XM and Sirius (have had XM for two years and just got Sirius as well).
