There is also an in-line connector on the coax cable for the antenna under the headliner. If that antenna has leaked, or potentially even other more common roof leaks like the sunroof drains being clogged or the clearance lights leaking, and water got to the cable than it would run down the cable and potentially corrode the connectors. Depending on the specific options the longer cable will either plug directly into the digital radio box hmer mentioned or it might connect to another shorter cable near the digital radio box and then plug into the box. So you really have a few places to potentially check. Could even be that the antenna itself has had water get into it internally and is going bad. The XM antenna is the small one on the drivers side on the roof. The flat part of it is for XM, the little mast that sticks up is for the Onstar cellular communications (it is a dual function antenna).
