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
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.
