Went to my daughters a couple of days ago, she lives about an hour from my house. On the return from her house, my Garmin 61 rebooted itself twice within about a 10 minute span of time. There was no power loss to occasion shut down or anything like that. One second it is tracking along the road I am traveling and the next second the screen goes blank and the unit goes through the restart procedure and eventually returns to tracking on the road I am traveling.
