in the proccess of fixing sunroof drains and drying carpet, I unhooked the xm anttena from the roof. I might have cut an anttena wire without knowing it.where do the wires attach from front and rear glass so i can track the wire back to radio. is an after market anttena an option?

You probably just disconnected it. It'* a pretty thick wire. In the Bonneville, the XM module is in the left corner of the trunk and the wire runs directly to it from the sharkfin.

And yes an aftermarket antenna is an option
