Course Computer Unit (CCU) - Reactor™ 40 Steer-by-wire

Garmin's CCU is the brain of the Reactor 40 autopilot system, containing sensory equipment used to determine heading and rate of turn. Connect the CCU to your boat's steering system and the NMEA 2000® network to communicate with your GHC™ 20 and optional NMEA 2000-compatible devices.
