Item Description
Important Considerations
Helm control
A dedicated helm control is not included in all autopilot packages. If you install the
autopilot without a dedicated helm control, the autopilot CCU must be connected to
the same NMEA 2000
®
network as a compatible Garmin chartplotter to configure and
control the autopilot system.
NMEA 2000
power cable
You should install this cable 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.
You must connect the NMEA 2000 power cable to a 9 to 16 Vdc power source.
NMEA 2000
network
You must connect the helm control or compatible Garmin chartplotter and the CCU
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 (
Building a Basic NMEA 2000 Network for the
).
ECU
CCU
You can mount the CCU in a non-submerged location near the center of the boat, in
any orientation (
CCU Mounting and Connection Considerations, page 5
).
Mount the CCU away from sources of magnetic interference.
ECU power cable
You must connect the ECU to a 12 to 24 Vdc power source. To extend this cable, use
the correct wire gauge (
Power Cable Extensions, page 9
).
CCU cable
To extend this cable to reach the ECU, you may need to use cable extensions (sold
separately) (
CCU Mounting and Connection Considerations, page 5
).
You must connect this cable to the alarm and the Shadow Drive
™
sensor.
NOTE: The Shadow Drive sensor is optional and sold separately
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 includes the necessary power and
feedback cables.
Drive unit 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, you must use a drive unit power cable (sold
separately) (
Connecting to an Existing Drive Unit, page 12
).
If you are using the autopilot with a solenoid drive unit, you must use a solenoid power
cable (sold separately) (
Connecting to a Solenoid Drive Unit, page 13
).
If you are using the autopilot with a drive unit not sold by Garmin or a solenoid drive
unit, you must install a Garmin rudder feedback sensor (recommended) or connect to
an existing rudder feedback sensor using a rudder feedback cable (sold separately)
(
Drive Unit Installation, page 11
).
Alarm
The alarm provides audible alerts from the autopilot system, and you should install it
near the primary helm station (
).
Shadow Drive
sensor connec
tion (optional)
The Shadow Drive sensor is an optional accessory that can be used only on a boat
with a hydraulic steering system (
Installing the Shadow Drive Sensor, page 15
).
