NMEA 2000 Considerations
®
If you are connecting to an existing NMEA 2000 network,
identify the NMEA 2000 power cable. Only one NMEA 2000
power cable is required for the NMEA 2000 network to operate
properly.
A NMEA 2000 Power Isolator (010-11580-00) should be used in
installations where the existing NMEA 2000 network
manufacturer is unknown.
If you are installing a NMEA 2000 power cable, you must
connect it to the boat ignition switch or through another in-line
switch. NMEA 2000 devices will drain your battery if the NMEA
2000 power cable is connected to the battery directly.
This device can connect to a NMEA 2000 network on your boat
to share data from NMEA 2000 compatible devices such as a
GPS antenna or a VHF radio. The included NMEA 2000 cables
and connectors allow you to connect the device to your existing
NMEA 2000 network. If you do not have an existing NMEA 2000
network you can create a basic one using cables from Garmin.
If you are unfamiliar with NMEA 2000, you should read the
"NMEA 2000 Network Fundamentals" chapter of the Technical
Reference for NMEA 2000 Products. You can find this document
using the "Manuals" link on the product page for your device at
www.garmin.com.
The port labeled NMEA 2000 is used to connect the device to a
standard NMEA 2000 network.

J1939 Engine Network Connection Considerations
You must use a Garmin GPSMAP J1939 accessory cable when
connecting the chartplotter to the J1939 engine network to
prevent corrosion due to moisture. Using a different cable voids
your warranty.
If you have an existing engine network on your boat, it should
already be connected to power. Do not add any additional power
supply.
This chartplotter can connect to an engine network on your boat
to read data from compatible devices such as certain engines.
The engine network follows a standard and uses proprietary
messages.
You should connect only one chartplotter to one engine network.
Connecting more than one chartplotter to one engine network
may result in unexpected behavior.
The port labeled J1939 is used to connect the device to the
existing engine network. You must route the cable within 6 m
(20 ft.) of the engine network backbone.
The Garmin GPSMAP J1939 accessory cable requires
connection to a power source and proper termination. For more
information on connecting to your engine network, see the
manufacturer's engine documentation.

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
™
view protected HDMI content (HDCP content) on the chartplotter
screen. HDMI video is shared across the Garmin Marine
Network, but it is not shared across the NMEA 2000 network.
HDCP content is not shared across the Garmin Marine 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 power
a media player stick. The USB port can supply up to 2.5 W to
power a media player stick.
You must make all cable connections in a dry environment.
