Well, it seemed to work on the way home from PT today. Lots of 59 second clips of the trip home. I'm still not sure why it didn't work on the way there, though it's a 30 minute drive, 1 hr round trip, so the whole trip, or at least part of the trip there should be on it. I didn't do anything different, although I didi forget to check it when I left this morning from home. When I got to the car after PT I did check the status, and it showed both the camera and sentry mode were on, when I put the car in D, sentry mode went off, but the camera stayed on. I didn't manually touch anything though, so it should have been on when I left home, but perhaps it wasn't on until sentry mode tuned on when I parked at PT. Anyway, I know it works at least sometimes, maybe I just haven't figured out if I still am doing something wrong. No surprises there!
