I ran a lowrance global map 3600 IGPS in my truck for about 3-4 years. Combined with a lakemaster chip, bigger screen it was nice, drove right to where I wanted to fish w/o the small screen. It also worked nice because my instrument cluster in my truck went out so I didn’t have a speedometer for a while so the GPS doubled as my speed gauge.
Any internal gps or even a puck mounted on the dash would work fine…all you need is a cig adapter for power.
Also when the ice wasn’t thick enough I would take this same unit and mount it via ram to my snowmobile, still plug into the cig adapter and away you go! I like the bigger screen when driving a sled or wheeler.
