Garmin CCU Extension Cable 5M

The Garmin CCU Extension Cable 5M (part number 010-11156-30) is designed to extend the communication distance between a Garmin CCU (Control Center Unit) and an ECU (Engine Control Unit) beyond the standard 3-meter limitation. This 5-meter cable enables flexible installation layouts on vessels where the control head must be mounted at a distance greater than the factory-default cable length allows. With a 16.4-foot reach, this extension cable accommodates larger pilothouse configurations and complex helm arrangements common on offshore fishing boats and cruising vessels.

The 5M specification provides the mid-range option within Garmin's CCU extension cable lineup, sitting between the 3-meter base cable and the longer 15-meter and 25-meter variants. This length is ideal for moderate-sized vessels where the engine room, helm station, or control console cannot be positioned within immediate proximity. The cable maintains signal integrity over its full length, preserving the real-time data transmission required for engine monitoring, navigation control, and system diagnostics. Proper cable routing and strain relief at connection points ensure longevity in the harsh marine environment where salt spray and vibration present ongoing challenges.

This extension cable serves boat owners, marine technicians, and retrofit installers who need to reconfigure existing Garmin marine electronics systems. It is particularly suited for vessels undergoing helm upgrades, navigation system relocations, or expansion of control station layouts. Whether you're retrofitting a fishing platform with extended monitoring capabilities or installing a new control head away from the engine compartment, the 5M cable provides the intermediate reach necessary for custom marine electrical architectures.

Garmin's marine CCU extension cables are engineered to OEM specifications and maintain compatibility with compatible Garmin marine systems. The 5M length offers a practical balance—longer than standard but more manageable than maximum-distance cables—making it a common choice for mid-sized cruising boats, offshore fishing vessels, and commercial marine applications where equipment placement requires strategic separation between control and engine electronics.
