J1939 Network Connection Considerations
You must use a Garmin GPSMAP J1939 accessory cable when
connecting the chartplotter to the J1939 network to prevent
corrosion due to moisture. Using a different cable voids your
warranty.
This chartplotter can connect to a J1939 network on your boat to
read data from compatible devices such as certain engines and
generators. Like the NMEA 2000 network, the J1939 network
follows a standard and uses proprietary messages.
You should connect only one chartplotter to one J1939 network.
Connecting more than one chartplotter to one J1939 network
can result is unexpected behavior and errors.
The port labeled ENGINE/J1939 is used to connect the device
to the existing J1939 network. You must route the cable 6 m (20
ft.) away from the J1939 backbone.

Video Considerations

To prevent corrosion due to moisture, you must use Garmin
GPSMAP accessory cables when connecting the chartplotter to
the video source or display. Do not connect a media player stick
directly into the back of the chartplotter. Using different cables or
connecting a media player stick into the back of the chartplotter
voids your warranty.
This chartplotter allows video input from HDMI video sources,
such as a Chromecast device or a Blu-Ray

HDCP content is not shared across the NMEA 2000 network.
Through the HDMI OUT port, you can duplicate the chartplotter
screen on another device, such as a television or monitor. You
cannot view HDCP content on the duplicated screen.
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 need a Garmin GPSMAP USB OTG adapter cable
to connect a media player stick. You must make all cable
connections in a dry environment.
The USB port can supply up to 2.5 W to power a media player
stick.

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.
