Garmin GPSMAP® 2-Pin Power/Data Cable - 6'

The Garmin GPSMAP 2-Pin Power/Data Cable — 6' is a dedicated connectivity solution designed for Garmin's GPSMAP marine navigation systems. This 6-foot 2-pin cable delivers both power and data transmission simultaneously, eliminating the need for separate connections and reducing clutter at the helm. For anglers and boaters who rely on GPS chartplotters for navigation, depth finding, and waypoint management, a reliable power/data interface is mission-critical—a loose connection or incompatible cable can mean the difference between a smooth fishing run and a disabled navigation system miles from shore.

The 6-foot length provides enough cable run from a boat's power distribution panel or battery bank to a mounted GPSMAP unit on the console, gunwale, or cabin without requiring daisy-chaining or Y-adapters. The 2-pin connector design is industry-standard for earlier and mid-generation GPSMAP models, ensuring compatibility with a wide range of Garmin chartplotters and sounder units. This cable handles both 12V DC power delivery and serial/USB data communication in a single sheathed run, reducing installation complexity and improving reliability compared to piecing together multiple connectors. The integrated design also minimizes electromagnetic noise that can degrade sonar performance—a critical concern when running sensitive transducers for precise bottom imaging.

This cable is essential for weekend anglers setting up new GPSMAP units, serious offshore fishermen replacing worn connectors, and boaters performing system maintenance or reconfiguration. It's equally valuable for recreational cruisers, commercial fishing operations, and anyone upgrading to a new Garmin chartplotter who needs a fresh, properly terminated power/data line. Carry a spare on board—marine environments expose connectors to salt spray, moisture, and corrosion, and a backup cable can mean the difference between a minor troubleshooting stop and a dead-in-the-water emergency.
