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.
HDMI Out Video Considerations
NOTICE
To prevent corrosion due to moisture, you must use Garmin
GPSMAP accessory cables when connecting the chartplotter to
the video display. Using different cables voids your warranty.
The GPSMAP 12x3 chartplotter has HDMI out capability to
duplicate the chartplotter screen on another device, such as a
television or monitor.
The Garmin GPSMAP HDMI accessory cable is 4.5 m (15 ft.)
long. If you need a longer cable, you should use an active HDMI
cable only. You need an HDMI coupler to connect the two HDMI
cables.
You must make all cable connections in a dry environment.
