The Panasonic CQ RX470U is a XM ready type of stereo.  When a radio states it is XM READY this means it has the ability to run a Satellite tuner which is sold as a seperate piece of equipment.  The Satellite antenna plug is on the seperate tuner.  The Panasonic takes the newer style tuner SIRIUS/XM shown here as the SXV200V1.  This tuner will give you the best of Sirius and the best of XM.
