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.
• 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.
Using the bail-mount bracket as a template, mark the pilot
1
holes .
Using a 3 mm (1/8 in.) drill bit, drill the pilot holes.
2
Secure the bail-mount bracket to the surface using the
3
included washers and wood screws .
Install the bail-mount knobs on the sides of the device.
4
Place the device in the bail-mount bracket, and tighten the
5
bail-mount knobs.
Install the trim caps by snapping them in place around the
6
edges of the device.
Flush Mounting the Device
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 powder coating, 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 drill holes and use the included nut plates and
machine screws. The nut plates can add stability to a thinner
surface.
• You can punch and tap holes, and use the included machine
screws.
Trim the template, and make sure it fits in the location where
1
you want to mount the device.
Secure the template to the mounting location.
2
Using a drill bit according to the list below, drill one or more of
3
the holes inside the corners of the solid line on the template
to prepare the mounting surface for cutting.

holes.
If the mounting holes on the device do not line up, mark the
9
new hole locations.
Based on your mounting method, drill or punch and tap the
10
outer holes on the template:
• For the included wood screws, drill 3.5 mm (9/64 in.) holes,
and skip to step 18.
• For the included nut plate and machine screws, drill
3.5 mm (9/64 in.) holes in the outer hole locations.
• For the included machine screws without the nut plate,
punch and tap M3 holes, and skip to step 18.
If you are using a nut plate, starting in one corner of the
11
template, place a nut plate over the hole drilled in the
previous step.
The other hole on the nut plate should line up with the
inner hole on the template.
If the inner hole on the nut plate does not line up with the
12
inner hole on the template, mark the new hole location.
If you are using a nut plate, using a 3 mm (1/8 in.) drill bit, drill
13
a hole in the inner hole location.
Repeat to verify placement of the remaining nut plates and
14
holes on the template.
Remove the template from the mounting surface.
15
Starting in one corner of the mounting location, place a nut
16
plate on the back of the mounting surface, lining up the
holes.
The raised portion of the nut plate should fit into the inner

device to the water ground of the boat to help avoid the
interference.
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.
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 28 AWG, 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.
NMEA 0183 Device Connections
This diagram illustrates two-way connections for both sending
and receiving data. You can also use this diagram for one-way
communication. To receive information from a NMEA 0183
device, refer to items , , , and when connecting the
Garmin device. To transmit information to a NMEA 0183 device,
refer to items , , , and when connecting the Garmin
device.
Lamp and Horn Connections
The device can be used with a lamp, a horn, or both, to sound or
flash an alert when the chartplotter displays a message. This is
optional, and the alarm wire is not necessary for the device to
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.

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.
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 chartplotter has HDMI out capability to
duplicate the chartplotter screen on another device, such as a
television or monitor.
The Garmin GPSMAP HDMI accessory cable is 4.5 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.
