Garmin 5M Extension Cable f/GHP™ 10

The Garmin 5M Extension Cable for GHP 10 is an essential accessory for boaters who need to position their autopilot control head (CCU) further from the electronic control unit (ECU) than the standard 3-meter connection allows. After years running marine systems on center consoles and larger cruisers, I've learned that flexible mounting options separate good autopilot installations from great ones. This 16.4-foot extension cable solves the real-world challenge of routing control displays to helm stations where crew ergonomics demand it, whether you're retrofitting an older vessel or building a new helm layout from scratch.

Built to Garmin's marine-grade standards, the 5M extension cable maintains signal integrity over longer runs without degradation to autopilot responsiveness or steering accuracy. The shielded construction protects against electromagnetic interference from diesel engines, generators, and VHF radio systems—noise sources every experienced skipper knows can plague poorly isolated autopilot wiring. At just 0.55 pounds, the cable remains lightweight and easy to route through cable conduit, bulkheads, and console infrastructure without adding unnecessary topside weight that affects trim or stability.

This extension cable is purpose-built for the GHP 10 marine autopilot system and works seamlessly with existing Garmin autopilot installations where helm layout or vessel refit demands additional wiring distance. Whether you're upgrading a sportfish rig, installing autopilot on a new trawler, or repositioning controls on a refurbished cruiser, the 5M cable delivers reliable performance and maintains the system integration Garmin users expect. Installation is straightforward—simply connect between your existing ECU and CCU harnesses for extended flexibility in control head placement.
