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.
To avoid possible personal injury and damage to your boat, the autopilot system should be installed by a
qualified marine installer. Specific knowledge of marine steering and electrical systems is required for proper
installation.
You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances your
capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. Avoid
navigational hazards and never leave the helm unattended.
Always be prepared to promptly regain manual control of your boat.
Learn to operate the autopilot on calm and hazard-free open water.
Use caution when operating the autopilot near hazards in the water, such as docks, pilings, and other boats.
CAUTION
Failure to install and maintain this equipment in accordance with these instructions could result in damage or
injury.
When in use, beware of hot surfaces on the heat-sink, motor, and solenoid components.
When in use, beware the risk of entrapment or pinching from moving parts.
Installation Preparation
The autopilot system consists of multiple components. You should familiarize yourself with all of the
component mounting and connection considerations before beginning installation. You must know how the
components operate together in order to correctly plan the installation on your boat.
You can consult the layout diagrams to help understand the mounting and connection considerations.
You should lay out all of the components on the boat as you plan the installation to make sure your cables will
reach each component. If needed, extension cables (sold separately) for various components are available from
your Garmin
dealer or from garmin.com.
®
You should record the serial number of each component for registration and warranty purposes.
