Important Safety Information
WARNING
See the Important Safety and Product Information guide in the
product box for product warnings and other important
information.
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
fuse in place voids the product warranty.
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.
To obtain the best performance and to avoid damage to your
boat, install the device according to these instructions.

Mounting Considerations
The device can be mounted using the included bracket, or it can
be mounted flush with the dashboard using a flush-mount kit
(may be sold separately).
Before permanently installing any part of your device, you
should plan the installation by determining the location of the
various components.
• The mounting location must provide a clear view of the
screen and access to the keys on the device.
• The mounting location must be sturdy enough to support the
device and the mount.
• The cables must be long enough to connect the components
to each other and to power.
• The cables can be routed under the bail mount or behind the
device.
• 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.

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.
Stainless-steel screws may bind when screwed into fiberglass
and overtightened. Garmin recommends applying an anti-seize
lubricant to the screws before installing them.
Select the mounting hardware appropriate for your mounting
1
surface and for the bail-mount bracket.
Using the bail-mount bracket as a template, mark the pilot
2
holes through the screw holes.
Using a drill bit appropriate for the mounting hardware, drill
3
the four pilot holes.
Using the selected mounting hardware, secure the bail-mount
4
bracket to the mounting surface.
Install the bail-mount knobs À on the sides of the device.
5
Using a 9.5 mm (3/8 in.) drill bit, drill one or more of the holes
3
inside the corners of the solid line on the template to prepare
the mounting surface for cutting.
Using a jigsaw or rotary cutting tool, cut the mounting surface
4
along the inside of the solid line indicated on the template.
Place the device into the cutout to test the fit.
5
If necessary, use a file and sandpaper to refine the size of
6
the hole.
If your device has trim caps, use a pry tool, such as a flat
7
piece of plastic or a screwdriver, to carefully pry up the
corners of the trim caps À, slide the pry tool to the center Á,
and remove the trim caps.
Ensure the mounting holes on the device line up with the pilot
8
holes on the template.
If the mounting holes on the device do not line up with the
9
pilot holes on the template, mark the new pilot-hole locations
on your template.
Using a 3.2 mm (1/8 in.) drill bit, drill the pilot holes.
10
Remove the template from the mounting surface.
11
If you will not have access to the back of the device after you
12
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 weather caps.
Install the rubber gasket pieces on the back of the device.
13
The pieces of the rubber gasket have adhesive on the back.
Make sure you remove the protective liner before installing
them on the device.
Place the device into the cradle Á.
6
Place the cradle in the bail-mount bracket and tighten the
7
bail-mount knobs.
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.
Using a metal pry tool such as a screwdriver can damage the
trim caps and the device. Use a plastic pry tool when possible.
You can mount the device in your dashboard using the flushmount template and appropriate hardware.
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
2
Securely connect each cable to a port on the cradle.
14
Place the device into the cutout.
15
Secure the device to the mounting surface using the included
16
screws.
Install the trim caps by snapping them in place around the
17
edges of the device.
Installing the Cables and Connectors
Wiring to Power
Route the power cable from the swivel mount to the boat
1
battery or fuse block.
