The XM what brand does that go with? I have the Kenwood Z828 that is Sirus Satelite radio ready. I just need to get the special antenna (100 bones) and then subsribe (10 a month) the nice thing about it is that you can get 50 music and 50 talk stations cd quality and crystal clear. The only tim you will get bad reception isif you are in the chunnel or some really dense mountains or forests.
for thoses looking into this deck i highly recomend it not only for the satelight hook up but for it capabilities for playing CD, CDR, CDRW and MP3 encoded discs.
