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.
Read all installation instructions before proceeding with the

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.

Installing the Swivel Base

Running through the Mount

You should complete this procedure only if you are not running
