Overview

The Garmin 010-11654-00 is a suction cup mount with an integrated speaker for Montana 6xx handhelds and the Monterra, giving you a secure, removable place to mount the GPS and a way to hear audible navigation prompts. It powers the cradle through the included 12 V vehicle power cable, which makes it practical for pilothouse and cabin use where you already have an accessory socket.

On a boat, this style of mount is most useful when you want a temporary setup that moves between vehicles and vessels, or between different helms. It is a better fit for sheltered locations like behind a windshield than for open-deck mounting where spray, heavy weather, or constant sun can work the suction loose.

Key features

• Suction cup base that mounts on smooth, non-porous surfaces without drilling
• Integrated speaker on the cradle for audible guidance and alerts from compatible devices
• Compatible with Montana 600, Montana 600t Camo, Montana 650, Montana 650t, and Monterra
• Powered mount setup using the included 12 V vehicle power cable with a cigarette-lighter style plug
• Quick to remove and reposition, which helps when sharing one handheld between a truck, tender, and pilothouse
• Keeps the handheld at eye level for safer glances while underway or while running inshore routes

Compatibility and fit

This mount is intended for the Montana 6xx family and the Monterra: Montana 600, Montana 600t Camo, Montana 650, Montana 650t, and Monterra. Match your device name to that list before ordering, since the cradle fit and powered contacts are specific to these models.

Installation and setup

For best hold, place the suction cup on clean glass or smooth acrylic and press it down firmly so the seal is even all the way around. On boats, plan the location so the screen is readable from the helm and the cable can be routed without being pinched by a sliding window, door, or hatch. If the surface gets wet or dusty, the suction seal can weaken, so it helps to wipe the mounting area before reattaching.

Electrical and system integration

The included power lead is a vehicle-style 12 V plug, so it pairs naturally with boats that have a 12 V accessory outlet at the helm. If your boat uses a different style of power connection, use a properly protected adapter or outlet circuit so the cable stays secure in vibration and the plug does not work loose while underway.

Use cases on board

This is a good match for boaters who run a Montana or Monterra as a portable navigator, especially when the same handheld goes from the truck to the cabin or pilothouse. It also works well for skippers who want audible prompts while keeping the handheld mounted higher on a windshield instead of sitting loose on a console.

Maintenance and care

Keep the suction cup clean and free of sunscreen film, dust, and salt residue, since buildup can reduce holding power. When not in use, store the mount out of direct sun and high heat to help the suction material keep its shape over time.
