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, confirm that your package includes the items listed below. All the components, except the hydraulic pump, are included in the GHP 10 core box. If any parts are missing, contact your Garmin dealer immediately.

Record the serial number of each component in the space provided.

Main Components

The GHP 10 autopilot system consists of five main components: the

Electronic Control Unit (ECU), the Course Computer Unit (CCU), a hydraulic pump, the Shadow Drive interface.

Hydraulic Pump and Motor

The hydraulic pump (and motor) steers your boat by interacting with the hydraulic steering system, based on commands you enter using the

GHC 20. 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 size and type of steering system on your boat. The pump is in a separate box. For information on installing the pump, see the installation instructions included in the pump box.

Serial number 

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 establish a new straight line heading, the Shadow

Drive automatically reengages the autopilot.

Serial number 

GHC 20

The CCU acts as the brain of the GHP 10. The CCU contains the sensory equipment used to determine heading. The CCU connects to the

ECU and to the GHC 20 with a single cable. The CCU also connects to a NMEA 2000

®

network to communicate with the GHC 20, and to optional NMEA 2000-compatible GPS devices (

page 12 ).

Serial number 

ECu

The GHC 20 is the primary interface used to operate the GHP 10 autopilot system. Using the GHC 20, you engage and steer the GHP 10.

You also set up and customize the GHP 10 using the GHC 20.

The GHC 20 connects to a NMEA 2000 network to communicate with the CCU. The GHC 20 also connects with optional NMEA

2000-compatible devices such as a GPS device, to use advanced features of the GHP 10. If NMEA 2000-compatible devices are not available, you can connect the GHC 20 to optional NMEA

0183-compatible devices instead.

Serial number 

The ECU connects to the CCU and to the drive unit. The ECU controls the drive unit based on information from the CCU. The ECU powers both the CCU and the drive unit.

Cables and Connectors

The GHP 10 autopilot system includes multiple cables. These cables connect the components to power, to each other, to an alarm, and to optional devices.

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 alarm and to the yellow wire from the GHC 20.

nMEa 2000 Cables and Connectors

The NMEA 2000 cables connect the CCU and the GHC 20 to the

NMEA 2000 network. Either connect the CCU and the GHC 20 to an existing NMEA 2000 network using the included T-connectors and drop cables, or use all of the included NMEA 2000 cables and connectors to

build a NMEA 2000 network on your boat if needed ( page 12

).

CCu/ECu Interconnect Extension Cables

When installing the GHP 10 system, you may need to mount the

CCU farther than 16 ft. (5 m) from the ECU. Garmin offers optional replacement or extension cables for purchase if this is necessary.

GHC 20 nMEa 0183 Data Cable

This cable connects the GHC 20 to the yellow wire of the CCU, and to the same ground as the ECU (

page 12 ). This cable can also be used to

connect the GHC 20 to optional NMEA 0183-compatible devices ( page

14 ).

External tachometer Filter

If your tachometer source is a direct alternator connection or other signal larger than 12 Vdc, or if you sporadically receive tachometer errors, install an external tachometer filter (Garmin part number: 010-

11399-00), not included. Contact your local Garmin dealer or Garmin product support for ordering information.
