That sucks.
My old Sport Trac got broken into when it was left at the dealer overnight waiting on a part. Smashed two windows and stole my XM and all my CD's. I figure they thought the XM was a GPS, because when I call XM to report it stolen it becomes an instant paperweight.
Dealer fixed it, got me a new XM (better than the one I had), and paid me $200 for the CD's. Upside, they never noticed the $400 Valentine One radar detector under the seat.

Downside, one of the CD's was autographed and I can't replace that.
