I'd start by calling the folks that did the windshield replacement. Let them know the receiver is right there by the windshield so they know it's likely a result of their work.
The only suggestions I can think of for fixing it on your own is to pop the covers off and make sure everything is plugged in. The other idea is to disconnect the battery to force the car to reboot.
