It's a hand held unit, but I'm thinking of making some sort of bracket to set it in. I'm NOT drilling any mounting holes, so the design of the bracket will be a challenge to say the least. I learned the hard way not to set it up on the dash behind the windshield, the bouncing pressed the enter button and entered about fifty waypoints! Holding it while driving isn't too cool either, I definitely need both hands to run the boat. (Taking a picture while holding the GPS and doing 40mph wasn't one of my brighter moments, but luckily nothing bad happened. lol )
