• The CCU and the GHC 20 connect to the NMEA 2000 network.

If your boat does not have a NMEA 2000 network, one can be built

using the included NMEA 2000 cables and connectors

(page 13).

• To use advanced features of the GHP 10, optional NMEA

2000-compatible devices, such as a GPS device, can be connected to

the NMEA 2000 network.

Notice

The mounting surface must be at to avoid damaging the device when

it is mounted.

• The mounting location should provide optimal viewing as you

operate your vessel.

• The mounting location should allow easy access to the keys on the

GHC 20.

• The mounting surface must be strong enough to support the weight

of the GHC 20 and protect it from excessive vibration or shock.

• The area behind the surface must allow room for the routing and

connection of the cables.

There should be at least a 3-inch (8 cm) clearance behind the case of

the GHC 20.

• The location must be at least 8

in. (209 mm) from a magnetic

compass, to avoid interference.

• The location must be in an area that is not exposed to extreme

temperature conditions (page 19).

• You must connect the GHC 20 to the NMEA 2000 network.

• For the autopilot to function, you must correctly connect two wires

from the GHC 20 data cable:

◦ The yellow wire from the GHC 20 data cable must be connected

to the yellow wire of the CCU/ECU interconnect cable.

◦ The black wire from the GHC 20 data cable must be connected

to the same ground as the ECU.

• Optional NMEA 0183-compatible devices, such as a GPS device,

can be connected to the GHC 20 data cable (page 14).

For optimal performance in all conditions, Garmin recommends

connecting to a NMEA 2000 or analog tachometer speed source. Each

speed source in the table is listed in order of best to least in terms of

autopilot performance.

NMEA 2000

Engine

Data

• If your engine supports NMEA 2000 engine data,

and is connected to the same NMEA 2000 network

as the GHC 20 and the CCU, no other tachometry

connection is necessary. For more information on

the NMEA 2000 network, see page 12.

 Mercury and Volvo offer add-on NMEA

2000 gateways to share Mercury and Volvo engine

information over the NMEA 2000 network. If you

have a Mercury or Volvo engine, these adapters

provide the easiest installation and the most reliable

engine data transfer. See your marine dealer for

more details.

Tachometer • If your engine does not support NMEA 2000 engine

data, you can connect the GHP 10 autopilot system

to the tachometer of your boat using the bare-wire

portion of the CCU/ECU interconnect cable. In most

cases, this connection can be made behind the

dashboard at the tachometer display.

• For a list of common engine tachometry

connections, visit www.garmin.com/ghp10/ and click

the manuals quick link.

 If your boat uses an electrical system that

provides more than 12 Vdc, or if you sporadically

receive tachometer errors, install an external

tachometer lter (010-11399-00). Contact your local

Garmin dealer or Garmin product support for more

information.

GPS • GPS data can be used when tachometer data is

unavailable or unusable.

 GPS speed source data is supported only

with GHC 20 software version 3.00 or higher when

used with GHP 10 software version 3.30 or higher.

• When connected to the GHC 20, GPS data can be

sent to the GHP 10 by connecting the device to a

NMEA 2000 or NMEA 0183 network.

None • Although it is not recommended; some boats, such

as displacement hulls, can be congured to use no

speed source.

• No connections are necessary when the selected

speed source is ‘None’.
