my 1988 has the original knot meter, depth, and wind gauges I believe they are Auto Helm ST60. It also has an GPS that has a some what detailed map wise monitor in the cabin and gives lat. and long. at the helm (isn't working) . The Knot and depth are on one gauge and work well the wind meter is out for repair. My question is are these all stand alone gauges. I would like to update the GPS but I don't know if removing the old GPS would effect the other gauges if they are somehow integrated. It also has the original auto helm that works fine.
Thanks
