Default NMEA V2.3 sentence question

I can tell you from direct experience that when connected to my Furuno 1833C with the port set to transmit only the SOG sentence with either NMEA 2.0 or 1.5 format, the Yamaha FM gauge works fine. It actually works with the other sentences needed by my autopilot also turned on, but seems to hang up sometimes with more data.

In my case, I do need to hook up the NMEA (-) lead from the Furuno to the black wire on the FM because Furuno seems to have an isolated ground for the data ports.
