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

• 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

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. • The ECU power cable connects to the boat battery, and it can be extended if needed (Power Cable Extensions). Helm Control Connection Considerations • The helm control must connect to the NMEA 2000 network. • Optional NMEA 0183 devices, such as wind sensors, waterspeed sensors, or GPS devices can be connected to the helm control using a data cable (NMEA 0183 Connection Considerations).

Item Description Important Considerations Ä NMEA 2000 network The helm control and the CCU must be connected to a NMEA 2000 network using the included T-connectors (NMEA 2000 Connection Considerations). If there is not an existing NMEA 2000 network on your boat, you can build one using the supplied cables and connectors (Building a Basic NMEA 2000 Network for the Autopilot System).

If you plan to route the ECU power through a breaker or a switch near the helm, you should consider using an appropriately sized relay and control wire instead of extending the ECU power cable. 1 Route the connector-terminated end of the ECU power cable to the ECU, but do not connect it to the ECU. 2 Route the bare-wire end of the ECU power cable to the boat battery. If the wire is not long enough, it can be extended (Power Cable Extensions).

Corrosion Blocker NOTICE To ensure long life of all parts, apply corrosion blocker to the pump at least twice yearly. A marine-rated corrosion blocker should be applied to the pump after all hydraulic and electrical connections are made and the hydraulic system has been bled.
