Contact your local Garmin dealer or Garmin Product Support for
ordering information.
The alarm provides audible alerts from the GHP 12 (page 11).
This cable powers the ECU (page 10).
Included in the GHC 10 box, this cable connects the GHC 10 to the
yellow wire of the CCU, and to the same ground as the ECU
(page 12). This cable can also be used to connect the GHC 10 to
optional NMEA 0183-compatible devices (page 14).
The NMEA 2000 cables connect the CCU and the GHC 10 to the
NMEA 2000 network. Either connect the CCU and the GHC 10 to an
existing NMEA 2000 network using the included T-connectors and drop
cables, use all of the included NMEA 2000 cables and connectors to
build a NMEA 2000 network on your boat if needed (page 12).
