content: I take the unit off the bike every time I stop(I don't trust the locking screw).One time I did not fully secure the GPS into the cradle.While going down the road at 50+ miles per hour it flew off.I thought great there's $600 down the drain.I circled back and picked up the device.It was banged up in a few places (the corners were completely scuffed).I turned it on and it WORKED!I have fully tested it and everything works (it's now 15+ days since the incident).All-in-all a good GPS for those of us who are a little rough on our hardware.
