: Some GPS chart plotters have a single wire for NMEA signal ground. In such a case
connect the NMEA input (–) to the GPS chart plotter’s single NMEA signal ground wire, and
leave the NMEA output (–) open. In case the assignment of power supply and ground of a
GPS chart plotter to be used is different from that of the radio, connect the signal ground
wire of the GPS chart plotter to the ground terminal (GND) on the rear panel of the radio.
When connecting the external speaker, chart plotter, or external GPS
antenna, strip off about 1 inch (2.5 cm) of the specied wire’s insulation, then
splice the ends together.
