First of all, great site! I am a big fan of online auto forums, and so far, this one has been extremely informative. I picked up my 04 SL yesterday, with the factory installed Sirius unit, and decided to take advantage of the free activation and free two months of service. Well, unfortunately, it seems as though my sat receiver does not want to cooperate. I cannot receive the preview station at all, and after five attemps to send the activation code to the unit, the Sirius guy and myself decided that this may be a hardware problem. Has anyone else had a similar problem? I know it wouldn't be out of the question for the receiver to be dead, but if anyone has any input, I would really appreciate it.
