nMEa 2000 Connection Considerations
• The CCU and the GHC 10 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.
GHC 10 Mounting Considerations
• 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 10.
• The mounting surface must be strong enough to support the weight
of the GHC 10 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 10.
• The location must be at least 9
compass, to avoid interference.
• The location must be in an area that is not exposed to extreme
temperature conditions (page
GHC 10 Connection Considerations
• You must connect the GHC 10 to the NMEA 2000 network.
• For the autopilot to function, you must correctly connect two wires
from the GHC 10 data cable:
◦ The yellow wire from the GHC 10 data cable must be connected
to the yellow wire of the CCU/ECU interconnect cable.
◦ The black wire from the GHC 10 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 10 data cable

Speed Source Connection Considerations
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.
Speed appropriate Connection
Source
NMEA 2000 • If your engine supports NMEA 2000 engine data,
Engine and is connected to the same NMEA 2000 network
Data as the GHC 10 and the CCU, no other tachometry
connection is necessary. For more information on
the NMEA 2000 network, see
notE: 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.
• Refer to the owner's manual or shop manual
for your engine to identify the color codes and
location of the tachometer connections on your
boat.
• For a list of common engine tachometry
connections, visit
the manuals quick link.
notE: If your boat uses an electrical system that
provides more than 12 Vdc, or if you sporadically
receive tachometer errors, install an external
tachometer filter (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.
notE: GPS speed source data is supported only
with GHC 10 software version 3.00 or higher when
used with GHP 10 software version 3.30 or higher.
• When connected to the GHC 10, 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 configured to use no
speed source.
• No connections are necessary when the selected
speed source is 'None'.
