NMEA 0183 with Audio Cable Pinout

The NMEA® 0183 with audio cable includes bare wires and an RCA connector for an audio out connection to a stereo, including Fusion® stereos. This optional cable (010-12390-21) can be purchased from garmmin.com or your local Garmin® dealer.

After installing, you can connect the RCA connector to the AUX input of the stereo, so the chartplotter's HDMI® input is output to the stereo.

This pinout information is for the NMEA 0183 with audio cable.
