The bundled GHC 50 control instrument has a sunlight-readable 5-inch touchscreen for setting and adjusting autopilot behaviour at a glance, and integrates with NMEA 2000 networks and compatible chartplotters so autopilot control and status can also be managed from a networked helm display rather than only the dedicated instrument. Being a Volvo Penta-specific corepack, this configuration is engineered to interface directly with Volvo Penta's own electronic steering/drive system rather than a generic hydraulic or mechanical steering setup - Garmin also offers equivalent corepack configurations for Seastar, Yanmar, and pod-drive systems, but each is matched to its specific drive electronics. This class of autopilot is aimed at larger yachts where precise, automated course-keeping meaningfully reduces the workload on the person at the helm during long passages. The GHC 50 instrument's compact roughly-3.6-inch-diameter footprint, with the sensor/instrument unit weighing under 160 grams, makes it an easy add to an existing helm panel without requiring major dash modifications, and it's rated to operate reliably across a wide -15°C to 55°C temperature range for genuine year-round marine use.
