I just got an 08 yukon and I have been a subscriber of sirius for years now. I call sirius to find out if I could transfer one of my sirius accounts to the yukon. They told me by the end of this month I could or I could pick what stations I wanted and pay per channel. I would like to have sirius but not sure if that is possible with the nav.?
