Overview

The Garmin 010-12100-12 is a zumo Socket Arm Mount kit that secures a compatible zumo navigator on an AMPS-style mount and a 1-inch ball-and-socket arm for easy positioning at the helm.

The short, metal double-socket arm measures 1.75 in from socket center to socket center (2.38 in overall) and tightens with a side screw, so you can set the viewing angle and lock it down when the boat is moving. The included cable has bare power, audio, and data wires, which suits a clean hardwired install when you want to run wiring through a dash, console, or electronics box.

Key features

• Snap-in mount supports portrait or landscape orientation for a compatible zumo navigator.
• AMPS-style mounting interface for pairing with common dash plates and brackets.
• Short metal double-socket arm clamps to 1-inch ball bases and adjusts with a side tightening screw.
• Arm length: 1.75 in center-to-center (2.38 in overall) for a low-profile install near the wheel, grab rail, or console face.
• Cable included with bare power, audio, and data wires for hardwiring and tidy cable routing.

What's included

• Snap-in mount
• Mounting hardware
• AMPS arm/ball socket assembly
• Cable with bare power, audio, and data wires

Installation and setup

Mount the AMPS interface to a solid surface such as a helm dash panel, electronics pod, or a bracket fastened to the console. On boats, seal any new fastener holes and use backing where needed to prevent flex and cracking. Set the arm tension so the unit stays put under vibration but can still be repositioned when you are setting up a route at the dock.

Compatibility and fit

This mount is intended for compatible Garmin zumo navigators that use the matching snap-in cradle style. If you are mixing components from an existing ball system, confirm you are using 1-inch ball parts so the sockets clamp correctly and hold their angle under motion.

Wiring notes

The cable is supplied with bare leads, which is helpful for routing through a console and terminating inside a dry area. Use marine-grade heat-shrink connectors, provide strain relief, and cap any unused audio or data leads so they cannot wick moisture. Keep splices and connectors away from direct spray and rinse-down zones when possible.

Use on board

This setup is a good match for skippers who run a zumo as a secondary navigator on a small helm, a tender, or a personal watercraft where space is tight and vibration is constant. It also works well when you want the screen close enough to read while standing, without a long arm that can swing or drift out of position.
