Garmin CCU Extension Cable 15M

The Garmin CCU Extension Cable 15M (MPN 010-11156-31) extends your chartplotter control head up to 49.2 feet from the engine control unit, solving the primary limitation that confines most integrated marine systems to 9.8 feet of cable separation. Built to Garmin's marine-grade specifications, this 15-meter extension cable maintains full signal integrity across the longer run, allowing helm station flexibility that standard installations cannot achieve.

Marine installations demand reliable cabling that withstands salt spray, UV exposure, and constant vibration. The CCU extension cable is engineered for the harsh saltwater environment where standard 3-meter runs fall short. Whether you're configuring a center console where the helm is distant from engine mounted electronics, or retrofitting a larger vessel where cable routing requires extra length, the 15-meter option bridges gaps that 5-meter or 25-meter alternatives may not justify. Garmin offers this cable in three lengths specifically because layout flexibility is essential to proper system integration.

Offshore anglers, cruising boaters, and commercial operators frequently encounter situations where electronics must be positioned away from engine compartments—whether for aesthetic design, operational ergonomics, or structural constraints. The 15-meter extension cable accommodates larger hulls, dual-engine layouts, and remote pilothouse configurations where standard connectivity becomes impossible. This is a foundational component for any Garmin CCU system that requires custom cable management beyond factory specifications.

Available in 5-meter (16.4'), 15-meter (49.2'), and 25-meter (82.0') lengths, Garmin's extension cable lineup reflects real-world installation demands across recreational and commercial marine applications. Stock this cable when configuring multi-station navigation systems or when retrofitting older vessels with modern chartplotter technology.
