Now comes DailyRoads.
This automates the entire process. Set Video and/or photo recording, set how long to record, let it record in the background, let it auto record as soon as you dock, shut off when you take off the dock. There are numerous settings. It will also overlay the speed from gps (which is not 100% accurate), the gps location, and the time.
