data cable
This cable should be installed only if you are
connecting the autopilot to optional NMEA 0183
devices, such as a wind sensor, a water-speed
sensor, or a GPS device (
).
Â
NMEA 2000
power cable
This cable should be installed only if you are
building a NMEA 2000 network. Do not install
this cable if there is an existing NMEA 2000
network on your boat.
The NMEA 2000 power cable must be connected
to a 9 to 16 Vdc power source.
Ã
NMEA 2000
network
The helm control and the CCU must be
connected to a NMEA 2000 network using the
included T-connectors (
).
If there is not an existing NMEA 2000 network on
your boat, you can build one using the supplied
cables and connectors (

Å
CCU
The CCU can be mounted in a non-submerged
location near the center of the boat, in any
orientation (
).
The CCU must be located away from sources of
magnetic interference.
Æ
ECU power
cable
The ECU must be connected to a 12 to 24 Vdc
power source. To extend this cable, use the
correct wire gauge (
Ç
CCU cable
To extend this cable to reach the ECU,
extensions (sold separately) may be necessary

CCU Mounting and Connection Considerations
This cable connects to the alarm.
È
Drive unit
This diagram shows only the electrical
connections for the drive unit (sold separately).
Detailed installation instructions are included with
the drive unit.
If you purchased a drive unit from Garmin, it will
come with the power and feedback cables
needed.

power and
feedback
cables
The drive unit power cable cannot be cut or
extended. If you are using the autopilot with a
drive unit not sold by Garmin, a drive unit power
cable (sold separately) must be used

If you are using the autopilot with a solenoid
drive unit, a solenoid power cable (sold
separately), must be used (
If you are using the autopilot with a drive unit not
sold by Garmin or a solenoid drive unit, you must
also install a Garmin rudder feedback sensor
(recommended), or connect to an existing rudder
feedback sensor using a rudder feedback cable
(sold separately) (
Alarm
The alarm provides audible alerts from the
autopilot system, and should be installed near
the helm control (

Installation Procedures
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.
After you have planned the autopilot installation on your boat
and satisfied all of the mounting and wiring considerations for
your particular installation, you can begin mounting and
connecting the components.
