Detailed description

The GHC™ 50 from Garmin is a dedicated control instrument for marine autopilot systems, designed to integrate with Garmin GHP Reactor™ autopilot systems. This 5-inch WVGA (800 x 480 pixels) touchscreen offers an intuitive and modern interface to precisely control your autopilot in various marine conditions.

High-brightness touchscreen with optimal readability

With a brightness of 1200 cd/m² (NIT), the GHC 50 ensures excellent visibility in full daylight and high-light conditions. Its anti-reflective and anti-fingerprint treated glass enhances readability and reduces eye strain during long passages. The compact dimensions (140 x 105 x 51 mm without sunshade) allow discreet integration into the dashboard, while the premium design blends seamlessly with other Garmin GPSMAP® equipment.

NMEA 2000 connectivity and Garmin Marine Network

The GHC 50 connects via NMEA 2000 (power supply 9 to 16 Vdc) and features a Garmin Marine Network interface for software updates and synchronization with other Garmin devices. Power consumption is minimal: 220 mA under normal conditions (400 mA max) for a maximum power draw of 5.85 W. The unit is powered directly from the NMEA 2000 network, with no separate power connection required. ANT+® connectivity also enables the use of compatible wireless remotes, including quatix® marine watches and GRID™ 20 controls.

Marine-grade robustness and reliability

Constructed from fully sealed polycarbonate with sealing gaskets, the GHC 50 meets IPX7 standards (resistance to accidental immersion up to 1 meter for 30 minutes). Its housing supports operating temperatures from -15°C to 55°C, suitable for extreme marine environments. The lightweight design (328 g without sunshade, 375 g with) facilitates flush-mount installation on the dashboard. The magnetic safety distance is 20 cm, compatible with traditional compasses.

Installation and system integration

Installing the GHC 50 follows a standardized process with flush-mount installation using wood screws or threaded plates depending on the mounting surface. The installation kit includes a drilling template, adhesive rubber gaskets, M3 screws, finishing caps, and all necessary NMEA 2000 connectors (power cable, T-connectors, terminators). A Garmin Marine Network cable and adapter are provided to facilitate synchronization with other devices in the fleet. Unlike some competing models such as the Raymarine p70Rs, the GHC 50 prioritizes Garmin ecosystem integration over standalone interface autonomy.

Positioning within the Garmin lineup

The GHC 50 represents the current standard for Garmin autopilot control instruments for sailboats and powerboats. It replaces earlier generations of wired controls with a modern touchscreen interface while maintaining full compatibility with all GHP Reactor™ autopilots. Its native NMEA 2000 architecture positions it as the Garmin equivalent of the Simrad AP44, offering centralized autopilot control on a dedicated screen integrated into the overall navigation system.
