So I got a replacement unit from the great folks at Marine General in Duluth. (my new favorite store by the way! ) after my last one filled with water..
This new unit is not displaying the speed over ground. The overlay is there and the gps has signal and the trails are working fine just no SOG. I have tried a reset, Turning WAAS on and off and configuring the overlay data and i just cant get it to work. Any suggestions out there? Thanks…
