Garmin CCU Extension Cable 15M

Unlock Flexible Mounting Options for Your Garmin Marine Autopilot

Installing a Garmin marine autopilot like the GHP 20 requires precise placement of the CCU to ensure optimal performance and visibility from the helm. But what if your boat's layout demands more distance between the CCU and ECU? That's where this robust 15-meter extension cable steps in, giving you the freedom to position your control unit exactly where it works best—without compromising signal integrity or reliability.

Crafted specifically for demanding marine environments, this black extension cable features a threaded collar for secure, weatherproof connections. Whether you're retrofitting an existing setup or building a new one on a larger vessel, it bridges the gap up to 49.2 feet, far beyond the standard 3-meter limit.

Key Features That Stand Out on the Water

• Extended Reach: 15 meters of durable cabling lets you mount the CCU in the most convenient spot, ideal for center consoles, yachts, or multi-station boats.
• Secure Threaded Design: Ensures a tight, vibration-resistant fit that withstands rough seas and constant boat motion.
• Marine-Grade Build: Black jacket resists UV exposure, saltwater corrosion, and abrasion for long-term dependability.
• Plug-and-Play Simplicity: No complex splicing or adapters needed—just connect and extend your system's range seamlessly.

Perfect Compatibility for Seamless Integration

This extension cable pairs effortlessly with Garmin's GHP 20 autopilot systems, including the CCU components. It's also versatile enough for other compatible Garmin marine autopilots that rely on CCU-ECU communication. Boaters upgrading from shorter cables or expanding helm stations will appreciate how it maintains full autopilot functionality, from autopilot engagement to heading hold modes.

Pro Tip: Always verify your ECU model's port configuration during planning to ensure a straightforward install. This cable shines in setups where the helm is separated from the main electronics bay, common on fishing boats over 30 feet or cruising yachts.

Why Boaters Choose This Extension for Superior Performance

Short cables limit your options, forcing suboptimal placements that lead to glare, awkward viewing angles, or exposed wiring runs. With 15 meters of extension, you gain layout flexibility that enhances usability and safety. Imagine a clean dash install at eye level while keeping sensitive electronics tucked away in a dry locker—reducing clutter and improving your onboard experience.

Real-world advantages include reduced wiring hassles during refits, better weight distribution for stability, and the ability to add remote displays without signal loss. It's a small addition that delivers big gains in convenience and system reliability, especially during long offshore passages where every detail counts.

Easy Installation and Pro Tips for Longevity

Route the cable along existing wire chases or under decking for protection. Use zip ties and conduit in high-traffic areas to prevent chafing. Once connected via the threaded collars, test the full range of autopilot functions—course changes, wind vane steering, and shadow drive if equipped.

• Inspect connections seasonally for wear.
• Avoid sharp bends tighter than the cable's minimum radius to preserve internals.
• Pair with Garmin's waterproof Deutsch connectors for added protection in wet zones.
