Just wanted to throw out a post on the radio. I have an 05 SS/SC with the factory xm radio. The other day I started my car and the regular fm radio came on. I tried to get the xm back and i could not. no radio number or previews at all. i contacted xm and my account is fine they say. I know that xm is always on or at least you will get your radio number and preview even if you dont suscribe to it. I was wondering if anybody else had this problem. The dealer is fixing it for free.
