I had a similar experience. I parked at St. Francis Restaurant for about 90 minutes. I used my GPS to get there - I am from out of town. I left it plugged in on the seat and it was gone when I returned. The cord was still plugged in but the GPS was gone. I called the restaurant, the owner of Go Green who never called me back and the assistant who assured me someone would follow up - two weeks later and four phone calls to them and nothing. St. Francis you should lose these guys!
