Overview

The Garmin 010-11052-68 is the Course Computer Unit (CCU) for Reactor 40 autopilot installations that interface with Volvo-Penta steering systems. It is the sensor and processing hub that tracks the boat heading and rate of turn so the autopilot can steer based on real-time motion data.

The CCU ties into a NMEA 2000 network to exchange data with a compatible helm control and other NMEA 2000 devices on board. This part is commonly used when building a Reactor 40 system around a Volvo-Penta setup, or when replacing a failed course computer in an existing installation.

Key features

• Course Computer Unit (CCU) for Reactor 40 systems intended for Volvo-Penta steering integration
• Measures heading and rate of turn for autopilot steering calculations
• NMEA 2000 network connection for control and data sharing with compatible displays and onboard sensors
• Works on the same NMEA 2000 backbone as a GHC 20 control unit and other NMEA 2000-compatible devices
• Mounts on a rigid surface and should be kept clear of strong magnetic fields and high-current cabling to avoid sensor interference

Compatibility and fit

This CCU is intended for Reactor 40 autopilot configurations built around Volvo-Penta installations. It is not a complete autopilot by itself, and it relies on the rest of the Reactor 40 components, the correct steering interface hardware for the boat, and a properly built NMEA 2000 network.

For systems with more than one network on board, the CCU needs to be on the same NMEA 2000 network as the device used to configure and control the autopilot.

Installation and setup

Plan the mounting location before drilling. A spot near the center of the boat, away from speakers, large DC motors, and heavy battery cable runs, helps the CCU sense clean heading and turn-rate data. A handheld compass is a quick way to check for magnetic interference in the area you are considering.

After mounting, connect the CCU into the Reactor 40 harness and the NMEA 2000 network, then complete dockside setup and sea-trial calibration from the helm control or compatible Garmin display.

Use on board

This CCU is a good match for Volvo-Penta boats that run longer stretches under power and want consistent course keeping for cruising, fishing, and trolling. It is also the right replacement part when a Reactor 40 system loses heading or turn-rate information and the rest of the steering hardware checks out.
