my 92 coupe just got it's headunit stripped, while i was on vacation. they also ransacked the glove compartment (but nothing really important was in there) and threw that all on the floor of the car. my insurance also doesn't cover it. i was really sad and pissed off when i found it, so i think i know how you feel, but, in the end, there's nothing you can really do about it but protect yourself and your cars in the future.
