Intuitive Marine Autopilot Control for Seamless Navigation

The Garmin GHC™ 20 Marine Autopilot Control Unit is designed to enhance navigation control for both power and sail vessels. This advanced helm controller is compatible with both legacy and newer Garmin autopilot systems, providing seamless integration. Its large 4-inch color glass-bonded display ensures exceptional visibility, offering a 170-degree viewing angle and an anti-glare finish to prevent fogging. For added convenience, it can be controlled via the optional handheld wireless remote or the quatix® marine GPS watch, featuring ANT® wireless technology.

Superior Readability in Any Condition

With enhanced readability for both day and night, the GHC 20 features a high-contrast color scheme that improves visibility in bright sunlight. At night, the unit offers multiple display options, including full-color mode, red/black, or green/black schemes, along with a dimmer control for optimal night-time viewing.
