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 will void 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.

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.
Using the included hardware and template, you can mount the 
device using one of two methods. You can use the included 
bracket and hardware to bail mount the device, or you can use 
the included template and hardware to flush mount the device in 
the dashboard. If you want to mount the device using an 
alternative method where it appears flat with the front of the 
dashboard, you must purchase a flat-mount kit (sold separately, 
with professional installation recommended) from your Garmin®
dealer.
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 all 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.
