Garmin 010-11129-00 Power/Data Cable 7 Pin For GHC20

The Garmin 010-11129-00 Power/Data Cable 7 Pin For GHC20 is the essential connectivity bridge between your Garmin marine autopilot system and NMEA 0183-compatible navigation devices. Designed specifically for users operating GMI 20 or GHC 20 control heads, this cable enables seamless integration with external instruments, allowing centralized command of steering and navigation functions from a single helm interface. Whether you're upgrading an existing installation or building a new integrated system, this 7-pin connector cable provides the reliable power and data transmission your vessel's autopilot requires.

The cable features a distinctive 90-degree connector design that solves a critical installation challenge: mounting in confined helm spaces or achieving flush panel integration without mechanical strain on the connectors. The 7-pin configuration carries both power delivery and digital NMEA 0183 protocol signals through a single robust cable, eliminating the need for multiple separate connections. Engineered to Garmin's marine-grade standards, this cable withstands the corrosive saltwater environment, temperature fluctuations, and vibration typical of commercial and recreational vessel operations. The 90-degree angled connector reduces cable stress at the device port, extending service life and minimizing connection failures during extended cruising or offshore deployment.

Marine professionals and vessel owners standardized on Garmin autopilot systems will find this cable indispensable for expanding system capability and integrating third-party navigation or radar equipment. Installation fits tightly in wheelhouses with limited panel real estate, making it ideal for retrofit applications on smaller craft or crowded commercial pilothouse layouts. Compatible exclusively with GMI 20 and GHC 20 systems, this genuine Garmin cable ensures compatibility and warranty coverage, with weight of 0.22 lbs making it practical for spares storage aboard. Order the Garmin 010-11129-00 to maintain reliable helm integration and keep your autopilot and navigation systems communicating seamlessly at sea.
