The back window on my A4 was smashed, don't ask. It has all the wiring for the antenna and heater so it doesn't look like an easy job replacing it. The connectors look like they're inside the pillars, means all that has to come apart. Also there's a bunch of trim that should probably be replaced with the window. I hesitate to call an auto glass shop, and I know the dealer will most likely be very expensive.

Any suggestions on which way to proceed?
TIA
