Fusion® MS-NRX Remote Troubleshooting
If a Fusion® MS-NRX remote does not turn on, or turns on but does not see the stereo, it is likely an issue with the NMEA 2000 network the remote and stereo are connected to. See Connecting a Fusion Stereo to a Wired Remote for NMEA 2000 troubleshooting specific to the stereo and remote, and see NMEA 2000 Technical Reference Guide for Garmin Marine Devices for complete information on NMEA 2000 specifications.
If the NMEA 2000 network is set up properly according to those instructions:
Replace the NMEA 2000 cable going to the remote and stereo
Replace the T connector the remote or stereo cable is connected to
If applicable, check that NRX Power is turned on on the stereo by going to
Menu > Settings > Power OptionsNRX Power should only be enabled if the stereo and remotes are the only devices on the NMEA 2000 network
NRX Power is capable of powering up to 3 remotes
If on a larger NMEA 2000 network with multiple devices, check that the LEN value does not exceed 20
LEN values for Garmin® devices are located in the owner's manual
