Installing a marine autopilot system on your boat often means dealing with tricky layouts where the Course Computer Unit (CCU) and Electronic Control Unit (ECU) need to communicate over longer distances. That’s where the Garmin CCU/ECU Interconnect Cable shines, offering a reliable 20-meter (65.6 feet) extension designed specifically for Garmin’s GHP 10 and GHP 10V autopilot systems. This black cable ensures seamless connectivity without signal loss, keeping your autopilot performing flawlessly even on larger vessels.
Built to withstand the harsh marine environment—salt spray, vibrations, and constant moisture—this interconnect cable goes beyond basic wiring. It simplifies installations that might otherwise require custom splicing or shorter runs, saving you time and frustration during setup.
Why Choose the 20M Garmin CCU/ECU Cable for Your Autopilot Setup
Perfect Length for Bigger Boats: At 20 meters, it bridges gaps between the CCU (typically mounted near the helm) and ECU (often closer to the drive unit), ideal for center consoles, yachts, or multi-hull designs where components are spread out.
Marine-Grade Durability: Constructed with UV-resistant, waterproof materials that resist corrosion, ensuring long-term reliability in saltwater conditions. No more worrying about frayed wires from constant exposure.
Plug-and-Play Simplicity: Directly compatible with bare wire connections on GHP 10 systems, it mates perfectly without adapters, reducing installation errors.
Enhanced System Performance: Maintains data integrity for precise course holding, NMEA 2000 integration, and autopilot responses, so you can focus on navigation rather than troubleshooting.
Versatile Alternative: If your boat needs less reach, Garmin also provides a 10-meter option, but this 20M version handles demanding layouts effortlessly.

Pro Tips for Seamless Installation
Plan Your Route: Measure the distance between CCU and ECU, accounting for bends and cable ties to avoid sharp angles that could stress the jacket.
Secure Properly: Use marine-grade zip ties or conduit to protect from chafing against engine mounts or deck hardware.
Weatherproof Connections: Apply dielectric grease to bare wire ends before crimping or soldering for extra corrosion resistance.
Test Thoroughly: After connecting, power up the system and run a sea trial to verify autopilot engagement and tracking accuracy.
Integrate with NMEA Network: This cable supports GHP 10’s full NMEA 2000 backbone, enabling data sharing with chartplotters and sensors.
Many installers report cutting setup time in half compared to makeshift extensions, making it a go-to for DIY boaters and pros alike.
Long-Term Maintenance for Peak Performance
Regular checks keep this cable in top shape: Inspect for abrasion every six months, especially near high-traffic areas. Rinse with fresh water after saltwater exposure, and avoid direct sunlight storage when trailering. With proper care, it supports years of uninterrupted autopilot operation, giving you peace of mind on open water.
