3. If you will be cutting the hole with a jigsaw instead of a 3
mm) hole saw, use a / in. (10 mm) drill bit to drill a pilot hole as

8
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 flush-
mount template.
5. If necessary, use a file and sandpaper to refine the size of the hole.
6. Place the GHC 10 into the cutout to confirm 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 10 from the cutout.
9. Drill the four / in. (3.2 mm) pilot holes.

If you are mounting the GHC 10 in fiberglass, use a countersink bit
as advised in the notice.
10. Remove the remainder of the template.
11. Place the GHC 10 into the cutout.
12. Securely fasten the GHC 10 to the mounting surface using the
supplied screws.
If you are mounting the GHC 10 in fiberglass, use a anti-galling
lubricant as advised in the notice.
13. Snap the mounting covers
Connecting the GHC 10
For the autopilot system to function correctly, you must connect two
wires from the GHC 10 data cable (yellow and black).
1. Connect the yellow wire from the GHC 10 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
2. Connect the black wire from the GHC 10 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.
Multiple GHC 10 Considerations
You can install multiple GHC 10 devices (sold separately) to control the
autopilot from different locations on the boat.
• All additional GHC 10 devices must be at software version 3.0 or
later.
• All additional GHC 10 devices must be connected to the
NMEA 2000 network (page
• To use an additional GHC 10 to turn on the autopilot, connect the
yellow and black wires from the additional GHC 10 to the same
wires as the primary GHC 10.
◦ If you connect additional GHC 10 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 10 to turn on the
autopilot, then the additional GHC 10 enters standby mode when
12
into place.

the primary GHC 10.
Connecting the Devices to a nMEa 2000
network
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 10 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
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.
Connecting the GHC 10 to an Existing nMEa 2000
network
1. Determine where to connect the GHC 10 ➊ to your existing NMEA
2000 backbone ➋
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 10 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 10.
