: XM Stopped Showing up on the NAV Unit

01-20-07, 03:52 PM
The XM radio in my '03 STS suddenly became unavailable. The NAV unit stopped showing that XM is even installed. When I press the BAND button, it indicates that only AM, FM 1, FM 2, and WX is available.

Can anyone out there answer the question, "What's the deal?"
