I am connecting the XB-8000 to a Garmin 3210C via NMEA0183. I want to make sure I have the connections correct.
1. Do I have to connect a heading sensor? I don't use an external heading sensor. I just use the Garmin.
2. Garmin has NMEA ports. Each port has two wires, a data RX and a data TX on each port.
How do you recommend I connect the NMEA Garmin to the XB-8000?
