Had my stereo and CD's stolen from my car 5 years ago. The funny thing was I as I walked up to the passanger side of car and saw wires dangling from dash my first thought was "how did my CD player fall out of the dash." It wasn't till I turned the corner and saw broken glass on the ground that I put two and two together.
The insurance company said they would pro-rate CD player, but for loss of actual CD's would have to file a home owners claim against my parents plan ( happened just prior to moving out), and would only cover approx. 5 dollars per CD. I had somewhere in the neighborhood of 130 CD's and it was an odd mix Bill Squire, Charlie Daniels, Tracy Chapman, Metallica, Primus, Incubus, Stones, Zepplin, Dr. Dre, Bone-thugs, etc... So who ever stole was probably like WTF, but I guess they needed it more than me.
Anyway, sorry for your loss and hopeful the mope gets his in the end.
