Just a cleaner look placing the GPS under the dash, mounted directly to the fiberglass. Near the center corner there is a stiff wire that is wedged against the top surface, so I located the GPS there, so that is has some extra holding power with the adhesive velcro. Initially I put the unit on the dash to get a signal, then once the signal was strong I played with it a couple times while under by boat canopy. Never a lost signal. Turned it on/off and instantly it found the satellites. VERY COOL INDEED!!!
