Connecting the Autopilot Gateway 1. Open the Volvo multilink bus and disconnect the multilink breakout cable. 2. Connect the proprietary Volvo connector ➊ from the Autopilot Gateway to the multilink bus using the included Y-cable. ➊ ➋ 3. Close the Volvo multilink bus. 4. Connect the CCU interface connector ➋ to the CCU cable. GHC 20 Installation Install the GHC 20 by flush-mounting it in the dashboard near the helm, connecting it to the yellow wire from the CCU interconnect cable, and connecting it to a NMEA 2000 network. To use advanced features of the GHP 10V, optional NMEA 2000-compatible or NMEA 0183-compatible devices, such as a GPS device, can be connected to the NMEA 2000 network or connected to the GHC 20 through NMEA 0183. 5. If necessary, use a file and sandpaper to refine the size of the hole. 6. Place the GHC 20 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 20 from the cutout. 9. Drill the four 7/64 in. (2.8 mm) pilot holes. If you are mounting the GHC 20 in fiberglass, 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 fiberglass, use a anti-galling lubricant as advised in the notice. 14. Snap the decorative bezel ➊ into place. ➊ Mounting the GHC 20 Notice The temperature range for the GHC 20 is from 5°F to 158°F (from -15°C to 70°C). Extended exposure to temperatures outside of this range (in storage or operating conditions) may cause failure of the LCD screen or other components. This type of failure and related consequences are not covered by the manufacturer's limited warranty. If you are mounting the GHC 20 in fiberglass, when drilling the four pilot holes, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid any cracking in the gel-coat layer when the screws are tightened. Stainless-steel screws may bind when screwed into fiberglass and overtightened. Garmin recommends applying an anti-galling, stainless anti-seize lubricant to the screws before installing them. Before you can mount the GHC 20, you must select a mounting location (page 5). 1. Trim the flush-mount template and ensure it will fit in the location where you plan to mount the GHC 20. The flush-mount template is included in the product box, not in these instructions. The flush-mount template has adhesive on the back. 2. Remove the protective liner from the adhesive on the back of the template and apply it to the location where you plan to mount the GHC 20. 3. If you will be cutting the hole with a jigsaw instead of a 317/32 in. (90 mm) hole saw, use a 3/8 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 flushmount template. Connecting the GHC 20 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 interconnect cable. If the cable is not long enough, extend the yellow wire with 22 AWG (.33 mm2) wire. 2. Connect the black wire on the GHC 20 data cable to the same ground location as the CCU. If the cable is not long enough, extend the black wire with 22 AWG (.33 mm2) wire. 3. Solder and cover all bare-wire connections. Multiple GHC 20 Considerations 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 9). • 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. 8 GHP 10V Installation Instructions

GHC 20 Installation
Install the GHC 20 by flush-mounting it in the dashboard near the helm,
connecting it to the yellow wire from the CCU interconnect cable, and
connecting it to a NMEA 2000 network.
To use advanced features of the GHP 10V, optional NMEA
2000-compatible or NMEA 0183-compatible devices, such as a GPS
device, can be connected to the NMEA 2000 network or connected to
the GHC 20 through NMEA 0183.
Mounting the GHC 20
Notice
The temperature range for the GHC 20 is from 5°F to 158°F (from
-15°C to 70°C). Extended exposure to temperatures outside of this
range (in storage or operating conditions) may cause failure of the
LCD screen or other components. This type of failure and related
consequences are not covered by the manufacturer’s limited warranty.
If you are mounting the GHC 20 in fiberglass, when drilling the
four pilot holes, it is recommended to use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will
help to avoid any cracking in the gel-coat layer when the screws are
tightened.
Stainless-steel screws may bind when screwed into fiberglass and
overtightened. Garmin recommends applying an anti-galling, stainless
anti-seize lubricant to the screws before installing them.
Before you can mount the GHC 20, you must select a mounting location
(
page 5
).
1.
Trim the flush-mount template and ensure it will fit in the location
where you plan to mount the GHC 20.
The flush-mount template is included in the product box, not in
these instructions.
The flush-mount template has adhesive on the back.
2.
Remove the protective liner from the adhesive on the back of the
template and apply it to the location where you plan to mount the
GHC 20.
3.
If you will be cutting the hole with a jigsaw instead of a 3
17
/
32
in. (90
mm) hole saw, use a
3
/
8
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 flush-
mount template.
5.
If necessary, use a file and sandpaper to refine the size of the hole.
6.
Place the GHC 20 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 20 from the cutout.
9. Drill the four

64
in. (2.8 mm) pilot holes.
If you are mounting the GHC 20 in fiberglass, use a countersink bit
as advised in the notice.
10. Remove the remainder of the template.

marine sealant around the gasket to prevent leakage behind the
dashboard.

Connecting the GHC 20
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 interconnect cable.
If the cable is not long enough, extend the yellow wire with 22
AWG (.33 mm
2
) wire.
2.
Connect the black wire on the GHC 20 data cable to the same
ground location as the CCU.
If the cable is not long enough, extend the black wire with 22 AWG
(.33 mm
2
) wire.
3. Solder and cover all bare-wire connections.
Multiple GHC 20 Considerations
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 9
).
•
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.
