Sorry to hear about your car, bk. That sucks. I wonder if the creeps who stole your GPS are thinking "This is the most spontaneous thing I've ever done!"
I've only had 2 car break-ins, but both were in LA while I was working on films, and both on Melrose. The first time all they got was an overcoat. The second time, tapes and EDLs, my briefcase with camera and plane ticket, etc. Since the tapes contained (tasteful) nudity, the producers were quite concerned that they might end up someplace weird and were worried about getting sued. Not a fun day. Argh...
