2008 GL550 radio/cd/xm radio trouble

All of a sudden the xmradio ..radio and cd are having power up problems. When I turn the key if the 6 cd stacker stays on red for all 6.. the units power right up. If they flash red on the stacker the error on the radio “ No satellite radio” the fm radio will have channels with no sound and the cd stacker does not appear in the list. I am getting ready to hook up my Star system but wondering if anyone has had this type of problem?? This just appeared yesterday and of course I have a week long hunting trip coming up.
Definitely not a fuse .. I am thinking either the Sam unit or relay … because when it errors if I just turn the key off and back on a few times the error will go away and everything starts to work properly.. thanks for any help Bill
