Overview

The Garmin 010-12123-00 is a fitted protective cover for GPSMAP 800 Series fixed-mount chartplotters, sized for GPSMAP 820, 820xs, and 840xs units. It covers the face of the display when the boat is at the dock, on a trailer, or stored between trips, helping keep sun, salt spray, and grime off the screen.

On helms that see regular washdowns or sit exposed to weather, a cover like this helps keep the front of the unit cleaner and reduces the chance of scratches from gear brushing past. Remove the cover before using the chartplotter so the screen and controls are fully accessible.

Key features

• Made to fit Garmin GPSMAP 820, GPSMAP 820xs, and GPSMAP 840xs units
• Covers the screen and front bezel while the chartplotter is not in use
• Helps block sun exposure and keeps spray residue and dock dust off the display face
• Useful for open consoles, flybridges, and sailboat cockpits where electronics stay exposed between runs
• Simple cover you can put on and remove by hand as part of your normal shutdown routine

Compatibility and fit

This cover matches the housing and bezel shape used on the GPSMAP 820, GPSMAP 820xs, and GPSMAP 840xs. Since Garmin housings vary by series and screen size, confirm the exact model number on your unit before ordering to avoid a loose fit.

Installation and on-board use

With the chartplotter already mounted, align the cover to the front of the unit and press it on until it seats around the edges. Many boaters keep it on whenever the boat is unattended, during transport, or while moving rods, tackle, and dock gear around the helm.

Maintenance and care

After saltwater exposure, rinse with fresh water and let it dry before storing it below. Skip harsh cleaners and solvents that can haze the surface over time.
