Overview

The Garmin 010-10920-00 is a replacement swivel mounting bracket for Garmin 400-series fishfinders, chartplotters, and sounders. It gives a stable, adjustable mount at the helm so you can tilt and swivel the display to a viewing angle that works from the wheel, the leaning post, or when you are standing to run the boat.

This bracket is commonly used with Garmin 4-inch GPSMAP 4x0 and Fishfinder 400-series units, where the screen position matters for glare control and quick checks while underway.

Key features

• Replacement swivel mount bracket for Garmin 400-series marine displays
• Tilt and swivel adjustment to set a comfortable viewing angle at the helm
• Used with common 4-inch Garmin units such as Fishfinder 300C/400C and GPSMAP 420/421/430/440/441 models
• Helps keep a small-format display secure on a dash, console face, or electronics box top where space is limited

Compatibility and fit

This is a mount bracket, not a power or network accessory. Fit depends on your specific Garmin display using the swivel bracket pattern from the 400-series family. If you are replacing an existing swivel mount on one of the compatible units, this part matches the mounting style those installations use.

If your boat has been refit over the years, double-check the model number on the display and compare the bracket style to your current mount before ordering.

Installation and setup

Plan the mounting location so the display can rotate and tilt without hitting the windshield frame, throttle binnacle, grab rail, or the lip of an electronics box. A flat surface at the helm with enough clearance behind the unit makes it easier to route the existing cabling without tight bends.

After mounting, set the viewing angle with the boat in its normal running attitude. On fast center consoles and smaller fishing boats, a slight upward tilt often improves readability when you are standing and scanning ahead.

Use on board

This bracket is a good match for boats running a compact Garmin 400-series display where the helm position changes between sitting and standing, such as bay boats, smaller offshore rigs, and many sailboats with tight pedestal space. It is also useful when a display has to be mounted off-center and needs regular angle changes to stay readable.
