Step 2: Connect the GXM 51 Antenna to Your NMEA 2000 Network The GXM 51 is packaged with a NMEA 2000 T-connector and a NMEA 2000/audio cable. You will use these two components to connect the GXM 51 to your existing NMEA 2000 network. If you do not have an existing NMEA 2000 network, you will need to install a NMEA 2000 network on your boat. For more information on NMEA 2000, visit www.garmin.com. To connect the GXM 51 to your existing NMEA 2000 network: 1. Determine an appropriate location to connect the GXM 51 to your existing NMEA 2000 backbone. GXM 51 antenna 2.
