GHP 10 Package Contents and Tools Needed
The GHP 10 autopilot system consists of multiple components. Familiarize yourself with all of the components before beginning
installation. You must know how the components operate together in order to correctly plan the installation on your boat.
As you familiarize yourself with the GHP 10 components, conrm that your package includes the following items. All the components
except for the hydraulic pump are included in the GHP 10 core box. The pump is packaged separately. If any parts are missing, contact
your Garmin dealer immediately.
The Main Components
The GHP 10 autopilot system consists of ve main components: the Electronic Control Unit (ECU), the Course Computer Unit
(CCU), a hydraulic pump, the Shadow Drive
The Course Computer Unit (CCU)
The CCU acts as the “brain” of the GHP 10. The CCU contains the sensory equipment used to determine
heading and engine speed. The CCU connects to the Electronic Control Unit (ECU), to the GHC 10, and
to the tachometer of your boat with a single cable. The CCU also connects to a NMEA 2000® network to
communicate with the GHC 10, and to an optional NMEA 2000-compatible GPS device.
Garmin part number: 010-11052-00

The Electronic Control Unit (ECU)
The ECU connects to the CCU and to the pump. The ECU controls the pump based on information from
the CCU. The ECU powers both the CCU and the pump.

The Shadow Drive
The Shadow Drive is a sensor you install in the hydraulic steering lines of your boat. While the GHP 10 is
engaged, the Shadow Drive temporarily disengages the autopilot when you manually take control of the
helm. When you manually steer the boat in a straight line again, the Shadow Drive allows the autopilot to
resume control.
Garmin part number: 010-11054-00
The hydraulic pump (and motor) steers your boat by interacting with the
hydraulic steering system, based on commands you enter using the GHC
10. The pump is not included in the GHP 10 core package box because
the type of pump you use with your GHP 10 is determined by the engine
and steering system of your boat. The pump is in a separate box.

The GHC 10
Use the GHC 10 to operate the GHP 10 autopilot system. Using the GHC 10, you engage and steer
the GHP 10. You also set up and customize the GHP 10 using the GHC 10. The GHC 10 connects to
a NMEA 2000 network to communicate with the CCU and with an optional NMEA 2000-compatible
GPS device (to use waypoint and route information). If a NMEA 2000-compatible GPS device is not
available, you can wire the GHC 10 to an optional NMEA 0183-compatible GPS device instead.

Cables and Connectors
The GHP 10 autopilot system contains multiple cables. These cables connect the components to power, to each other, to an alarm, and
to optional devices such as a NMEA 0183-compatible GPS device.
CCU/ECU Interconnect Cable
This cable connects the CCU to the ECU. A portion of this cable contains color-coded wires with bare ends. These wires connect the
CCU to the tachometer of your boat, to the Shadow Drive, and to the alarm. (Garmin part number: 010-11055-00)
The Alarm
The alarm is wired to the CCU and provides audible alerts from the GHP 10. See page 18. (Garmin part number: 010-11056-00)
ECU Power Cable
This cable powers the ECU. Wire this to the battery of your boat as one of the last connections made in the GHP 10 installation.

Electrical/Data Connection and Mounting Considerations
The GHP 10 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 any components. Read the following
considerations and consult the diagram on the next page before you begin installation.
The Pump and the ECU
The pump must be located within 19 in. (0.5 m) of the ECU, mounted horizontally if possible. If you cannot mount the pump
•
horizontally, do not mount the pump vertically with the pump head (connectors) down.
•
The cables from the pump to the ECU cannot be extended.
The ECU power cable connects to the boat battery.
•
The CCU and the ECU
Do not mount the CCU or the ECU in a location where they will be submerged or exposed to wash-down.
•
•
Mount the CCU in the forward half of the boat, no higher than 10 ft. (3.05 m) above the waterline.
You can mount the CCU below the waterline, as long as it is not in a location where it will be submerged or exposed to wash-
•
down.
Mount the CCU bracket on a vertical surface or under a horizontal surface, so that the connected wires hang straight down.
•
•
Do not mount the CCU near magnetic material, magnets (speakers and electric motors), or high-current wires.
CCU at least 24 in. (0.61 m) away from movable or changing magnetic disturbances such as anchors, anchor chain, wiper motors,
tool boxes, and the autopilot pump. Use a handheld compass to test for magnetic interference in the area.
The CCU/ECU interconnect cable connects the CCU to the ECU, and is 91/2 ft. (3 m) long. If you cannot mount the CCU within
•
91/2 ft. (3 m) of the ECU, extension cables are available in lengths of 16
The CCU/ECU interconnect cable connects the CCU to the Shadow Drive, the alarm buzzer, the tachometer of the boat, and the
•
yellow CCU signal wire of the GHC 10 using wires with bare ends. See page 17 for wiring instructions and diagrams.
1
/2 ft. (5 m) and 49 ft. (15 m). (See page 4).
Mount the
The CCU and the GHC 10
The CCU and the GHC 10 connect to a NMEA 2000 network. If you do not have a NMEA 2000 network on your boat, the
•
equipment necessary to build one is provided. For instructions on setting up the NMEA 2000 network, see page 21.
You can connect an optional NMEA 2000-compatible GPS device to the NMEA 2000 network to use waypoint and route data with
•
the GHP 10.
The GHC 10
Wire the GHC 10 to the battery of the boat and to the yellow CCU signal wire of the CCU/ECU interconnect cable.
•
If you do not have an optional NMEA 2000-compatible GPS device, you can wire an optional NMEA 0183-compatible GPS
•
device to the power/data cable of the GHC 10 instead (see page 23).
The Shadow Drive
Install the Shadow Drive closer to the helm than to the pump.
•
Mount the Shadow Drive horizontally, as level as possible.
•
Mount the Shadow Drive at least 12 in. (0.3 m) away from magnetic material such as speakers and electric motors,
•
including the autopilot pump.
