Garmin Reactor™ 40 Mechanical/Retrofit/Solenoid Corepack without GHC™ (010-00705-48) is a versatile below-deck autopilot system engineered for powerboats and sailboats with cable, mechanical, or solenoid steering setups. Driven by a solid-state 9-axis AHRS CCU, it maintains precise course control in rough seas while minimizing rudder movement and power consumption. This corepack includes the ECU 12 to control compatible linear or solenoid drives and connects via NMEA 2000® for full operation through a networked Garmin chartplotter. (Drive units and rudder feedback sensors sold separately).
