Mounting Considerations
NOTICE
This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The
temperature range for this device is listed in the product specifications. Extended exposure to temperatures
exceeding the specified temperature range, in storage or operating conditions, may cause device failure.
Extreme-temperature-induced damage and related consequences are not covered by the warranty.
When selecting a mounting location, you should observe these considerations.
• The location should provide optimal viewing as you operate your boat.
• The location should allow for easy access to all device interfaces, such as the keypad, touchscreen, and card
reader, if applicable.
• The location must be strong enough to support the weight of the device and protect it from excessive
vibration or shock.
• To avoid interference with a magnetic compass, the device should not be installed closer to a compass than
the compass-safe distance value listed in the product specifications.
• The location must allow room for the routing and connection of all cables.
• When flush mounting the device, the location must not be a flat, horizontal surface. The location should be in
a vertical angle.
The location and viewing angle should be tested before you install the device. High viewing angles from
above and below the display may result in a poor image.

Bail Mounting the Device
NOTICE
If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
You can use the bracket to bail mount the device on a flat surface.
1Using the bail-mount bracket as a template, mark the pilot holes .
2Using a 3mm (1/8in.) drill bit, drill the pilot holes.
3Secure the bail-mount bracket to the surface using the included washers and wood screws .
4Install the bail-mount knobs on the sides of the device.
5Place the device in the bail-mount bracket, and tighten the bail-mount knobs.
6Install the trim caps by snapping them in place around the edges of the device.
Flush Mounting
NOTICE
Be careful when cutting the hole to flush mount the device. There is only a small amount of clearance between
the case and the mounting holes, and cutting the hole too large could compromise the stability of the device
after it is mounted.
Use only the included hardware when mounting this device. Using mounting hardware not provided with the
device may damage the device.
To avoid potential damage to the device housing, use only the included screws to mount the device. Using
screws other than the ones included will void your warranty.
Do not use the device as a template when drilling the mounting holes because this may damage the glass
display and void the warranty. You must only use the included template to correctly drill the mounting holes.
If you will not have access to the back of the device and the microSD memory card slots after installations, you
should install the microSD memory card prior to installation.
The included template and hardware can be used to flush mount the device in your dashboard. There are three
options for hardware based on the mounting surface material.
• You can drill pilot holes and use the included wood screws.
• You can punch and tap holes, and use the included machine screws.
• You can drill holes and use the included nut plates and machine screws. The nut plates can add stability to a
thinner mounting surface.

Garmin Marine Network Considerations
NOTICE
A Garmin Marine Network PoE Isolation Coupler (010-10580-10) must be used when connecting any third-party
device, such as a FLIR® camera, to a Garmin Marine Network. Connecting a Power over Ethernet (PoE) device
directly to a Garmin Marine Network chartplotter damages the Garmin chartplotter and may damage the PoE
device. Connecting any third-party device directly to a Garmin Marine Network chartplotter will cause abnormal
behavior on the Garmin devices, including the devices not properly turning off or the software becoming
inoperable.
This device can connect to additional Garmin Marine Network devices to share data such as radar, sonar,
and detailed mapping. When connecting Garmin Marine Network devices to this device, observe these
considerations.
• All devices connected to the Garmin Marine Network must be connected to the same ground. If multiple
power sources are used for Garmin Marine Network devices, you must tie all ground connections from all
power supplies together using a low resistance connection or tie them to a common ground bus bar, if
available.
• A Garmin Marine Network cable must be used for all Garmin Marine Network connections.
◦Third-party CAT5 cable and RJ45 connectors must not be used for Garmin Marine Network connections.
◦Additional Garmin Marine Network cables and connectors are available from your Garmin dealer.
• The NETWORK ports on the device each act as a network switch. Any compatible device can be connected to
any NETWORK port to share data with all devices on the boat connected by a Garmin Marine Network cable.
NMEA 2000 Considerations
NOTICE
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.
This device is not powered through the NMEA 2000 network. You must connect the device to a power source
(Connecting the Wiring Harness to Power, page10).
If you are unfamiliar with NMEA 2000, you should read the Technical Reference for NMEA 2000 Products at
garmin.com/manuals/nmea_2000.
The port labeled NMEA 2000 is used to connect the device to a standard NMEA 2000 network.

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 three NMEA 0183 devices in parallel to the Tx port to receive data output by this chartplotter.
• See the NMEA 0183 device installation instructions to identify the transmit (Tx) and receive (Rx) wires.
• You must use 22AWG (.33mm²), shielded, twisted-pair wiring for extended runs of wire. Solder all
connections and seal them with heat-shrink tubing.
• Do not connect the NMEA 0183 data wires from this device to power ground.
• The power cable from the chartplotter and the NMEA 0183 devices must be connected to a common power
ground.
• The internal NMEA 0183 ports and communication protocols are configured on the chartplotter. See the
NMEA 0183 section of the chartplotter owner's manual for more information.
• See the chartplotter owner's manual for a list of the approved NMEA 0183 sentences that the chartplotter
supports.

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 consult the manufacturer of your engine or engine network when connecting the chartplotter. Some
manufacturers may have requirements you must follow when connecting to avoid unexpected behavior.
The port labeled J1939 is used to connect the device to the existing engine network. You must route the cable
within 6m (20ft.) 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.

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.
17

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 12x3/16x3 chartplotter models have HDMI out capability to duplicate the chartplotter screen on
another device, such as a television or monitor.
The Garmin GPSMAP HDMI accessory cable is 4.5m (15ft.) 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.
