Important Safety Information

 WARNING

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.

 CAUTION

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 (

Power and Data Layout

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 

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
• 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
• Portable or handheld compass (to test for magnetic 

interference)

• 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

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.
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.

• The area behind the mounting surface must allow room for 

the routing and connection of the cables.

Helm Control Connection Considerations

• The helm control must connect to the NMEA 2000

®

 network.

• Optional NMEA

®

 0183 devices, such as wind sensors, water-

speed sensors, or GPS devices can be connected to the 

helm control using a data cable (

NMEA 0183 Connection 

Considerations

).
