Hey sorry to hear about that.
I went through the same crap a year and a half ago. I was on Spring break, just enjoying myself, finally earning some money with my new job (high school part time), and I bought a new radio that wasn't really that expensive, like $100. Well I guess I was dumb and since I live in a pretty nice neighborhood I didn't take too many precautions and I had no alarm.
But I was with a friend, and we were headed to a party so I didn't want to drive. So we parked outside my house as normal, put my ipod in the glovebox thinking nothing will happen because it's been a month or two and no problems. Leave my radio headunit on (it wasn't that appealing). I wake up to find my back passenger wing window broken. They stole the faceplate off my head unit, didn't break naything but the window, stole my ipod, went throuhg everything. They looked in my trunk for subs/amp because they probably saw me blasting music or something, but luckily I hadn't gotten them installed yet.
But ya that sucked, that absolutely ruined my break because I was broke and was just starting to earn money and lost my $300 ipod, $100 haed unit. And had to get it replaced.
I was really pissed, so I really feel you. It seems like your older so you have some money to spend, but it sucks regardless. And obviously your situation is muc hworse than mine, but at least your insurance will probably take care of it.
Good luck.
