Mounting the Components
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.
You can mount the device using one of three methods. You can
use the included bracket and hardware to bail mount the device,
you can use the included template and hardware to flush mount
the device, or you can use the flat-mount kit (sold separately) to
mount the device flat with the dashboard. When selecting a
mounting location, observe these considerations.
NOTE: Not all mounting methods are available for all device
models. See the specific mounting-type section for more details
about your model.
• 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 the cables.
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 any cracking in the gel-coat layer when the screws are
tightened.
The bail-mounting hardware (screws and washers or nuts,
washers, and bolts) is not included. The holes on the bail-mount
bracket are 5/16 in. (7.9 mm) in diameter. Before you can bail
mount the device, you must choose mounting hardware that fits
the holes in the bail-mount bracket and securely attaches it to
your specific mounting surface. The size of the pilot hole
required depends on the mounting hardware you choose.
You can bail mount only the eight-inch and 12-inch models. Due
to the size of the 15-inch models, you must install them using
the flush-mount or flat-mount method.
1Using the included bail-mount bracket À as a template, mark
the location of the four pilot holes Á.
2Using a drill bit appropriate for your mounting hardware, drill
the pilot holes.
3Secure the bail-mount bracket to the surface using your
mounting hardware Â.
4Install the bail-mount knobs à on the sides of the device.

Antenna Mounting Considerations
You can mount the antenna on a flat surface, install it under
fiberglass, or attach it to a standard 1 in. OD, 14 threads per
inch, pipe-threaded pole (not included). You can route the cable
outside of the pole or through the pole. For optimal
performance, consider these guidelines when selecting the
antenna mounting location.
• To avoid interference with a magnetic compass, the antenna
should not be mounted closer to a compass than the
compass-safe distance value listed in the product
specifications.
• To ensure the best reception, the antenna should be
mounted in a location that has a clear, unobstructed view of
the sky in all directions À.
• The antenna should not be mounted where it is shaded by
the superstructure of the boat Á, a radome antenna, or the
mast.
• The antenna should not be mounted near the engine or other
sources of Electromagnetic Interference (EMI) Â.
• If a radar is present, the antenna should be mounted above
the path of the radar Ã. If necessary, the antenna may be
mounted below the path of the radar Ä.
• The antenna should not be mounted directly in the path of
the radar Å.
• The antenna should be mounted at least 3 ft. (1 m) away
from (preferably above) the path of a radar beam or a VHF
radio antenna Æ .
• On a sailboat, to prevent inaccurate speed readings caused
by excessive heeling, the antenna should not be mounted
high on the mast.
• The antenna provides more-stable readings when located
nearer to water level.

Testing the Mounting Location
1Temporarily secure the antenna in the preferred mounting
location and test it for correct operation.
2If you experience interference with other electronics, move
the antenna to a different location, and test it again.
3Repeat steps 1–2 until the antenna operates correctly.
4Permanently mount the antenna.
Surface Mounting the Antenna
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 any cracking in the gel-coat layer when the screws are
tightened.
Stainless-steel screws may bind when screwed into fiberglass
and overtightened. Garmin recommends applying an anti-
galling, stainless anti-seize lubricant to the screws before
installing them.
Before you permanently mount the antenna, you must test the
mounting location for correct operation (page 3).
1Using the surface-mount bracket À as your mounting
template, mark the three pilot-hole locations and trace the
cable-hole in the center of the bracket.
2Set the surface-mount bracket aside.
Do not drill through the bracket.
3Drill the three 1/8 in. (3.2 mm) pilot holes.
4Use a 1 in. (25 mm) hole saw to cut the cable hole in the
center.
5Place the seal pad Á on the bottom of the surface-mount
bracket, aligning the screw holes.
6Use the included M4 screws to secure the surface-mount
bracket to the mounting surface.
7Route the cable  through the 1 in. (25 mm) hole and
connect it to the antenna.
8Verify that the large gasket à is in place on the bottom of the
antenna, place the antenna on the surface-mount bracket,
and twist it clockwise to lock it in place.
9Secure the antenna to the mounting bracket with the
included M3 set screw Ä.
10Route the cable away from sources of electronic
interference.
Mounting the Antenna with the Cable Routed Outside the
Pole
Before you permanently mount the antenna, you must test the
mounting location for correct operation (page 3).
1Route the cable through the pole-mount adapter À, and
place the cable in the vertical slot Á along the base of the
pole-mount adapter.
2Screw the pole-mount adapter onto a standard 1 in. OD, 14
threads per inch, pipe-threaded pole (not included).
Do not overtighten the adapter on the pole.
3Connect the cable to the antenna.
4Place the antenna on the pole-mount adapter and twist it
clockwise to lock it in place.
5Secure the antenna to the adapter with the included M3 set
screw Â.
6With the antenna installed on the pole mount, fill the
remaining gap in the vertical cable slot with a marine sealant
(optional).
7Attach the pole to the boat if it is not already attached.
8Route the cable away from sources of electronic
interference.
Mounting the Antenna with the Cable Routed Through the
Pole
Before you permanently mount the antenna, you must test the
mounting location for correct operation (page 3).
1Position a standard 1 in. OD, 14 threads per inch, pipe-
threaded pole (not included) in the selected location, and
mark the approximate center of the pole.
2Drill a hole using a ¾ in. (19 mm) drill bit for the cable to
pass through.

9Route the cable away from sources of electronic
interference.
Mounting the Antenna Under the Deck
NOTICE
Before attaching the under-deck mounting bracket to the
surface, verify that the supplied screws will not penetrate the
surface. If the supplied screws are too long, you must purchase
surface-appropriate screws to complete the installation.
Before you permanently mount the antenna, you must test the
mounting location for correct operation (page 3).
Because the antenna cannot acquire signals through metal, it
must be mounted under a fiberglass surface only.
1Place the adhesive pads À on the under-deck mounting
bracket Á.
2Place the antenna in the under-deck mounting bracket.
3Adhere the under-deck mounting bracket to the mounting
surface.
4Secure the under-deck mounting bracket to the mounting
surface with screws.
5Connect the cable to the antenna Â.
6Route the cable away from sources of electronic
interference.
Cable and Connection Considerations
NOTICE
A blue rubber seal is included for each DVI port on the device.
This seal must be installed between each DVI port and DVI-
cable connector to avoid damage to the connectors.
• For easer cable routing, the power, NMEA® 0183, and
Garmin Marine Network cables are packaged without the
locking rings installed. You should route the cables before
you install the locking rings.
• After connecting a locking ring to a cable, make sure the ring
is securely connected and the o-ring is in place so the power
or data connection remains secure.
• The device should be connected to the same power source
as the card reader. If this is not possible, the devices must
be connected to the same ground.
Station Connection Considerations
This device can be set up in conjunction with other compatible
Garmin devices to work together as a station. When planning
stations on your boat, observe these considerations.
• Devices prior to the GPSMAP 8000 series and GPSMAP
8500 cannot be used in a station.
• Although it is not necessary, it is recommended that you
install all of the devices you plan to use in one station near
each other.
• No special connections are necessary to create a station, as
long as all of the devices are connected to the Garmin
Marine Network (page 6).
• Stations are created and modified using the device software.
See the owner's manual provided with the device for more
information.
Connecting to Power
WARNING
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate

Additional Grounding Considerations
This device should not need any additional chassis grounding in
most installation situations. If interference is experienced, the
grounding screw on the housing can be used to connect the
device to the water ground of the boat to help avoid the
interference.
Garmin Marine Network Considerations
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.
• 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.
• There are four NETWORK ports on the device that 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 have an existing NMEA 2000 network on your boat, it
should already be connected to power. Do not connect the
included NMEA 2000 power cable to an existing NMEA 2000
network, because only one power source should be connected
to a NMEA 2000 network.
If you are installing the included 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 allows you to either connect the device to your
existing NMEA 2000 network or create a basic NMEA 2000
network if needed.
If you are unfamiliar with NMEA 2000, you should read the
“NMEA 2000 Network Fundamentals” chapter of the Technical
Reference for NMEA 2000 Products on the included CD-ROM
or click 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. The ports labeled ENGINE and
HOUSE are reserved for future use and should not be
connected to a standard NMEA 2000 network.

NMEA 0183 Connection Considerations
• The installation instructions provided with your NMEA 0183-
compatible device should contain the information you need
to identify the transmitting (Tx) and receiving (Rx) A (+) and
B (-) wires.
• When connecting NMEA 0183 devices with two transmitting
and two receiving wires, it is not necessary for the NMEA
2000 bus and the NMEA 0183 device to connect to a
common ground.
• When connecting a NMEA 0183 device with only one
transmitting (Tx) wire or with only one receiving (Rx) wire,
the NMEA 2000 bus and the NMEA 0183 device must be
connected to a common ground.
Basic NMEA 0183 Connections
These diagrams illustrate basic NMEA 0183 wiring used to connect your device to NMEA 0183-compliant devices. For more

• If the NMEA 0183-compliant device has only one input (RX) wire (no A, B, +, or -), leave the pink wire unconnected.
• If the NMEA 0183-compliant device has only one output (TX) wire (no A, B, +, or -), connect the orange/white wire to ground.
• Consult the installation instructions of your NMEA 0183-compliant device to identify the output A(+) and B(-) wires and input A(+)
and B(-) wires.
• Use 28 AWG, shielded, twisted-pair wiring for extended runs of wire.
• Solder all connections and seal them with heat-shrink tubing.
Advanced NMEA 0183 Connections
There are four internal NMEA 0183 input ports (RX ports), and two internal NMEA 0183 output (TX ports) on the included NMEA
0183 data cable. You can connect one NMEA 0183 device per internal RX port to input data to your Garmin device, and you can
connect up to three NMEA 0183 devices in parallel to each internal TX port to receive data output by your Garmin device. Each
internal RX and TX 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 your NMEA 0183-compliant device. Refer to the
table and wiring diagrams when connecting the data cable to NMEA 0183 devices.
Consult the installation instructions for your NMEA 0183-compliant device to identify the output (TX) A (+) and B (-) wires and input
(RX) A (+) and B (-) wires. Use 28 AWG, shielded, twisted-pair wiring for extended runs of wire. Solder all connections and seal
them with heat-shrink tubing.
• For two-way communication with a NMEA 0183 device, the internal ports on the NMEA 0183 data cable are not linked. For
example, if the input of the NMEA-compliant device is connected to the internal output port 1 on the data cable, you can connect
the output port of your NMEA 0183-compliant device to any of the internal input ports (port 1, port 2, port 3, or port 4) on the
wiring harness.
• The ground wires on the NMEA 0183 data cable and your NMEA 0183-compliant device must both be connected to ground.
• See page 12 for a list of the approved NMEA 0183 sentences output by and input to your device.
• The internal NMEA 0183 ports and communication protocols are configured on the connected Garmin device. See the NMEA
0183 section or communication configuration section of the owner's manual provided with your Garmin device for more
information.

Video Input and Output Considerations
This device allows video input from composite, component, and
digital video sources, depending on the model, and video output
to a monitor. When connecting video input and output sources,
observe these considerations.
• The eight- and twelve-inch models have two composite-video
ports labeled CVBS 1 IN, and CVBS 2 IN. The fifteen-inch
models have four composite-video ports labeled CVBS 1 IN,
CVBS 2 IN, CVBS 3 IN, and CVBS 4 IN.
• The fifteen-inch models have one component-video port
labeled COMPONENT IN (480i/576i).
◦ The composite- and component-video ports use BNC
connectors. You can use a BNC to RCA adapter to
connect a composite-video source with RCA connectors
to these ports.
◦ The video from sources connected to these ports is
available only for display on the device or additional
monitor connected to the device. Composite or
component video is not shared across the Garmin Marine
Network or NMEA 2000 network.
• The fifteen-inch models have one video port labeled DVI-I
VIDEO IN that accepts video from digital or analog sources
using a DVI-D or DVI-I cable.
◦ If needed, you can use an HDMI to DVI-D converter to
connect an HDMI-compatible source to this device.
◦ If needed, you can use a VGA to DVI-I adapter to connect
a VGA source to this port.
• You can connect a display to the DVI-I VIDEO OUT port to
view a mirror image of the screen on a computer monitor or
HD TV using a DVI-D or DVI-I cable.
◦ If needed, you can use a DVI-D to HDMI adapter to
connect to an HD TV or other HDMI-compatible display.
◦ If needed, you can use a DVI-I to VGA adapter to connect
to a computer monitor or other VGA-compatible display.
• Although it is recommended to use DVI cables sold by
Garmin, high-quality third-party DVI cables may be used.

You should test the DVI cable by connecting the devices
before routing the cable.
