XM Satellite Radio Antenna Connection.

[Bella15]

I recently had some minor paint work done and my windshield replaced. The problem...XM does not work anymore! I called the shop (continental collision of Austin, TX) that completed the work and they told me that the antenna must have came unplugged some how. Besides from being angry at them and 1750 miles away now, I just want to find out where the connections are! Any help would be greatly appreciated!
