Match a compatible Yamaha Helm Master system with the Garmin Reactor 40 Steer-By-Wire Corepack for Yamaha Helm Master with GHC 50. This corepack includes a Reactor 40 autopilot, Autopilot Gateway, and GHC 50 control display for the specified Yamaha Helm Master system. A 9-axis solid-state AHRS forms the autopilot sensor architecture, while the GHC 50 uses a 5-inch touchscreen for onboard configuration and control. [158]

The system operates from 10V to 30V DC and connects through NMEA 2000 with the Yamaha gateway. Flush and bracket mounting are specified for the GHC 50, which measures 5.5 x 4.1 x 2.0 inches. The display carries an IPX7 rating and an operating temperature range of minus 15°C to 55°C. Compatibility should be checked against the installed Yamaha Helm Master system because Garmin specifies that this corepack is not compatible with Helm Master EX. [158]
