Garmin Reactor 40 Course Computer Unit (CCU)

This is a Garmin Reactor 40 Course Computer Unit (CCU) for marine autopilot systems. It's used and shows some light dust and surface wear, but the connectors look solid. It features the standard NMEA 2000 and Steering Bus ports on the front. This is the core brain for the autopilot system, designed to keep you on course even in rough water. It's a rugged little unit that mounts easily with the integrated tabs.
