12 GHP 10 Installation Instructions

3. If you will be cutting the hole with a jigsaw instead of a 3

in. (90

mm) hole saw, use a

in. (10 mm) drill bit to drill a pilot hole as

indicated on the template to begin cutting the mounting surface.

4. Using the jigsaw or the 3.5

in. (90 mm) hole saw, cut the mounting

surface along the inside of the dashed line indicated on the ush-

mount template.

5. If necessary, use a le and sandpaper to rene the size of the hole.

6. Place the GHC 20 into the cutout to conrm that the four mounting

holes are correct.

7. Select an option:

• If the mounting holes are correct, proceed to step 8.

• If the mounting holes are not correct, mark the correct locations

of the four mounting holes.

8. Remove the GHC 20 from the cutout.

9. Drill the four

in. (2.8 mm) pilot holes.

If you are mounting the GHC 20 in berglass, use a countersink bit

as advised in the notice.

10. Remove the remainder of the template.

11. Place the included gasket on the back of the device and apply

marine sealant around the gasket to prevent leakage behind the

dashboard.

12. Place the GHC 20 into the cutout.

13. Securely fasten the GHC 20 to the mounting surface using the

supplied screws.

If you are mounting the GHC 20 in berglass, use a anti-galling

lubricant as advised in the notice.

14. Snap the decorative bezel

For the autopilot system to function correctly, you must connect two

wires from the GHC 20 data cable (yellow and black).

1. Connect the yellow wire from the GHC 20 data cable to the yellow

wire from the CCU/ECU interconnect cable.

If the cable is not long enough, extend the yellow wire with 22

AWG (.33 mm

) wire.

2. Connect the black wire from the GHC 20 data cable to the same

ground location as the ECU.

If the cable is not long enough, extend the black wire with 22 AWG

(.33 mm

) wire.

3. Solder and cover all bare-wire connections.

You can install multiple GHC 20 devices (sold separately) to control the

autopilot from different locations on the boat.

• All additional GHC 20 devices must be connected to the

NMEA 2000 network (page 12).

• To use an additional GHC 20 to turn on the autopilot, connect the

yellow and black wires from the additional GHC 20 to the same

wires as the primary GHC 20.

◦ If you connect additional GHC 20 devices to turn on the

autopilot, you must turn them all off to turn off the autopilot.

◦ If you do not connect an additional GHC 20 to turn on the

autopilot, then the additional GHC 20 enters standby mode when

you turn it off, and the autopilot remains on until turned off by

the primary GHC 20.

Notice

If you have an existing NMEA 2000 network on your boat, it should

already be connected to power. Do not connect the included NMEA

2000 power cable to an existing NMEA 2000 network, because only

one power source should be connected to a NMEA 2000 network.

You can connect the GHC 20 to the CCU through an existing NMEA

2000 network. If you do not have an existing NMEA 2000 network on

your boat, all the parts needed to build one are supplied in the GHP 10

package (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.

For more information on NMEA 2000, go to www.garmin.com.

2. Disconnect one side of a NMEA 2000 T-connector from the

network.

3. If necessary, to extend the NMEA 2000 network backbone, connect

a NMEA 2000 backbone extension cable (not included) to the side

of the disconnected T-connector.

4. Add the included T-connector

➌

for the GHC 20 to the NMEA

2000 backbone by connecting it to the side of the disconnected

T-connector or backbone extension cable.

5. Route the included drop cable

➍

to the bottom of the T-connector

added in step 4, and connect it to the T-connector.

If the included drop cable is not long enough, you can use a drop

cable up to 20 ft. (6 m) long (not included).

6. Connect the drop cable to the to the GHC 20.
