Just got back from an overnight in the San Juans. Yesterday I noticed than the speed window on the C-80 was registering about 2-3 MPH less that the speed on the Navman. Both get their input from NMEA. Then today on the way back the speed indication on the C80 went to 0. In looking at the wiring I discovered a wire hanging loose and have no idea where it was connected. It looks as though it came out of a crimp type connector. The wire is one of the wires that comes from the GPS Raystar 125 ant. The brown one. Which in the manual says it should go to RTCM in /+. I have no idea what that means and also can't find any wiring diagrams showing the wiring of the four or five different plugs that plug into the back of the C80.
What also baffles me is that I am still getting GPS SOG in MPH on the Navman.
Anyone have any thoughts or info on this?
