Overview

The Garmin 010-12100-11 is a base plate that lets you mount a compatible zumo navigator using a 1 inch diameter rubber ball for adjustable viewing on a boat.

The rectangular plate uses a 4-hole AMPS pattern, which makes it easy to fasten to a flat surface and pair with many common 1 inch ball-and-socket arms. It is a solid option when you are replacing a worn base or setting up a clean mount point on a helm, console, or nav station.

Key features

• 1 inch diameter rubber ball for use with common 1 inch ball-and-socket mount arms
• Rectangular 4-hole AMPS mounting pattern for straightforward screw-down installs
• Ball mount allows wide angle adjustment so the screen is easier to read from different positions
• Replacement base plate format used with compatible Garmin zumo navigator mounting setups
• Mounting screws included

Installation and setup

Mount it on a firm, flat spot such as a dash top, helm pod, console face, or an electronics box. On thin panels, adding a backing plate or large washers helps keep the mount from flexing when the boat is pounding.

Dry-fit the plate first to confirm clearance for the arm and device, then tighten the fasteners evenly so the base sits flat and does not rock.

Compatibility and fit

This base plate is meant for Garmin zumo navigator mounting arrangements that use a 1 inch ball interface. Confirm your existing arm, cradle, and bolt pattern match the 1 inch ball size and the 4-hole AMPS layout before installing.

Use cases on board

This is a good match for boaters who want a small navigator they can swivel toward the helm seat, a standing driving position, or a passenger spot without moving the entire mount.
