Important Safety Information
See the Important Safety and Product Information guide in the
product box for product warnings and other important
information.
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.
When in use, beware of hot motor and solenoid components
and the risk of entrapment from moving parts.
Failure to install and maintain this equipment in accordance with
these instructions could result in damage or injury.
NOTICE
To avoid damage to your boat, the autopilot system should be
installed by a qualified marine installer. Specific knowledge of
hydraulic steering componentry and marine electrical systems is
required for proper installation.
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
from www.garmin.com.
You should record the serial number of each component for
registration and warranty purposes.

Tools Needed
• Safety glasses
• Drill and drill bits
• Wrenches
• 90 mm (3.5 in.) hole saw or a rotary cutting tool
• Wire cutters/strippers
• Phillips and flat screwdrivers
• Cable ties
• Waterproof wire connectors (wire nuts) or heat-shrink tubing
and a heat gun
• Marine sealant
• Marine corrosion inhibitor spray
• Portable or handheld compass (to test for magnetic
interference)
• Hydraulic hose with machine-crimped or field-replaceable
fittings that have a minimum rating of 1000 lbf/in
• Hydraulic T-fittings
• Inline hydraulic shut-off valves
• Hydraulic fluid
• Thread sealant
• Hydraulic bleeding equipment
• Anti-seize lubricant (optional)
NOTE: Mounting screws are provided for the main components
of the autopilot system. If the provided screws are not
appropriate for the mounting surface, you must provide the
correct types of screws.
Mounting and Connection Considerations
The autopilot components connect to each other and to power
using the included cables. Ensure that the correct cables reach
each component and that each component is in an acceptable
location before mounting or wiring any components.
Helm Control Mounting Considerations
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.
Using the included hardware and template, you can 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
(professional installation recommended) from your Garmin
dealer.
When selecting a mounting location, observe these
considerations.
• The mounting location should be at or below eye level to
provide optimal viewing as you operate your vessel.
• The mounting location should allow easy access to the keys
on the device.
• 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.
