function normally. When connecting the device to a lamp or 

horn, observe these considerations.
• The alarm circuit switches to a low-voltage state when the 

alarm sounds.

• The maximum current is 100 mA, and a relay is needed to 

limit the current from the chartplotter to 100 mA.

• To manually toggle visual and audible alerts, you can install 

single-pole, single-throw switches.

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.
Through the HDMI OUT port, you can 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.

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.

J1939 Engine Network Connection Considerations

NOTICE

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.
