Overview

The Garmin 010-11654-06 is a marine mounting kit that secures a compatible Montana-series handheld GPS at the helm while supplying hardwired power from your boat. It’s built for installations where you want the same handheld you use on shore to live on the console in rough water without relying on internal batteries.

The power lead connects to 10 to 50 V DC ship’s power, which covers typical 12 V and 24 V systems. The cable also provides serial data leads and a stereo jack for setups that use them, and the kit includes anti-glare screen protectors to help readability when sunlight and spray make the display harder to see.

Key features

• Hardwired power connection for boat systems from 10 to 50 V DC.
• Cradle and swivel-style mount hardware that lets you set a viewing angle at the helm.
• Serial data leads provided in the cable (yellow input, blue output, green ground) for compatible connections that use serial wiring.
• Stereo jack on the cable for audio output where supported by the connected device.
• Anti-glare screen protectors included to reduce reflections on open consoles and in bright cockpit light.
• Contact cover on the mount to help keep the cradle contacts protected when the device is removed between trips.

What’s included

• Marine mount and cradle assembly
• Power cable with bare-wire leads, serial data leads, and stereo jack
• Anti-glare screen protectors

Compatibility and fit

This mount is used with Garmin handheld units in the Montana 600 family and related models, including Montana 600, 600t, 610, 610t, 650, 650t, 680, 680t, and Monterra. It is also used with GPSMAP 276Cx. If your device has the same back-side cradle interface as these models, it will seat and lock into the mount correctly; if it does not, it will not.

Installation and wiring

Plan a mounting spot with a clear view of the screen and enough space for cable routing, with about 3 inches of clearance behind the mount for the cable bend and strain relief. The swivel base is typically secured with three #8 pan-head fasteners; avoid countersunk heads that can stress the bracket. Mounting hardware is not included, so match screws or bolts to your console material and thickness.

Wire the red and black leads to your boat’s main DC supply (10 to 50 V DC). If you are not using the serial data wires or audio connection, cap and secure them so they cannot short or chafe. Keep the mount and device contacts dry during installation and when swapping the handheld on and off the boat.

Use on board

This setup makes sense for skippers who move a handheld between a truck, a kayak, and the boat, but still want a stable, powered mount on the console for longer runs. It also fits smaller center consoles and sailboat cockpits where a fixed chartplotter is not the plan, but you still want the GPS in the same spot every trip.

Maintenance and care

After saltwater use, wipe down the cradle area and keep the contact cover in place when the handheld is off the boat. Check the cable for chafe where it passes through the console, and make sure the mount stays tight as the boat sees vibration over time.
