Installation Instructions
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the
product box for product warnings and other important
information.
CAUTION
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite
side of the surface.
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.
The mounting surface must be flat to avoid damaging the device
when it is mounted.
When selecting a mounting location, observe these
considerations.
• The mounting surface 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.
• If you are connecting this device to a wireless sensor, you
must install it in a location where it can communicate with the
wireless sensor.
• The area behind the mounting surface must allow room for
routing and connecting the cables.
Mounting the Device
NOTICE
If you are mounting the device in fiberglass, when drilling the
pilot holes, 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.
Stainless-steel screws may bind when screwed into fiberglass
and overtightened. It is recommended to apply an anti-seize
lubricant on the screws before installing them.
The included template and hardware can be used to flush mount
the device in your dashboard.
1Trim the flush-mount template and ensure it fits in the
location where you plan to mount the marine instrument.
The flush-mount template is included in the product box.
2Remove the liner from the adhesive on the back of the
template and adhere it to the location where you plan to
mount the marine instrument.
3If you plan to cut the hole using a rotary tool instead of a
90 mm (3.5 in.) hole saw, use a 10 mm (3/8 in.) drill bit to drill
a pilot hole to begin cutting the mounting surface.
4Using the 90 mm (3.5 in.) hole saw or rotary tool, cut the
mounting surface along the inside of the dashed line
indicated on the flush-mount template.
5If necessary, use a file and sandpaper to refine the size of
the hole.
6Place the marine instrument into the cutout to confirm that
the mounting holes on the template are in the correct
locations.
7If the mounting holes are not correct, mark the correct
locations of the mounting holes.
8Remove the marine instrument from the cutout.
9Drill the 2.8 mm (7/64 in.) pilot holes.
If you are mounting the marine instrument in fiberglass, use a
countersink bit as advised in the notice.
10Remove the remainder of the template.
11Place the included gasket on the back of the device and
apply marine sealant around the gasket to prevent leakage
behind the dashboard.
12If you will not have access to the back of the device after you
mount it, connect all necessary cables to the device before
placing it into the cutout.
NOTE: To prevent corrosion of the metal contacts, cover
unused connectors with the attached weather caps.
13Place the marine instrument into the cutout.
14Securely fasten the marine instrument to the mounting
surface using the supplied screws.
If you are mounting the marine instrument in fiberglass, use a
anti-galling lubricant as advised in the notice.
15Snap the bezel into place.

Connection Considerations
The marine instrument connects to power and to data sources
through a NMEA 2000® network.
Although the instrument cannot directly receive NMEA® 0183
data, it can display NMEA 0183 data from sources connected to
a GNX 20 or GNX 21 device (sold separately) on the same
NMEA 2000 network.
The instrument can also receive data from Nexus® instruments
and sensors using a GND™ 10 device (sold separately).
NMEA 2000 Connection Considerations
The marine instrument connects to a NMEA 2000 network on
your boat. The NMEA 2000 network provides power to the
marine instrument and data from NMEA 2000 devices such as a
speed sensor. The included NMEA 2000 cables and connectors
allow 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. To download the
reference, go to garmin.com/manuals/nmea_2000.
