Composite Video Considerations

This chartplotter allows video input from composite video sources using the port labeled CVBS IN. When 
connecting composite video, you should observe these considerations.
• The CVBS IN port uses a BNC connector. You can use a BNC to RCA adapter to connect a composite-video 

source with RCA connectors to the CVBS IN port.

• Video is shared across the Garmin Marine Network, but it is not shared across the NMEA 2000 network.
