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.

Touchscreen Controls for a Connected Computer

To prevent corrosion due to moisture, you must use Garmin
GPSMAP accessory cables when connecting the chartplotter to
the computer. Using different cables voids your warranty.
You can connect the chartplotter to a computer to see the
computer screen and to control the computer using the
chartplotter touchscreen. To see the computer screen, you must
connect the computer to the HDMI IN port. To control the
computer using the chartplotter touchscreen, you must connect
the computer to the USB port.
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.
The Garmin GPSMAP USB accessory cable is 4.5 m (15 ft)
long. If you need a longer cable, you should use a USB hub or
USB repeater extension cable only. You should make all cable
connections in a dry environment.

NMEA 0183 Connection Considerations
• The chartplotter provides one Tx (transmit) port and one Rx
(receive) port.
• Each port has 2 wires, labeled A and B according to the
NMEA 0183 convention. The corresponding A and B wires of
each internal port should be connected to the A (+) and B (-)
wires of the NMEA 0183 device.
• You can connect one NMEA 0183 device to the Rx port to
input data to this chartplotter, and you can connect up to
® stereos. This cable
