Overview

The Garmin 010-12390-43 is a trim piece snap cover that finishes the edge of a GPSMAP 8x24 glass-helm installation when a trim section is missing or damaged. The trim piece measures 22.7 inches long by 0.5 inches wide and is used on compatible displays in the GPSMAP 8x24 family, including GPSMAP 8424 and GPSMAP 8624.

It snaps into place around the display opening to clean up the look of the helm after electronics service, a refit, or a dash rebuild. This is a trim component for the mount area, not a protective cover for the screen.

Key features

• Trim piece snap cover for GPSMAP 8x24 glass-helm mounting
• Fits compatible Garmin units such as GPSMAP 8424 and GPSMAP 8624
• Trim piece size: 22.7 in (L) x 0.5 in (W)
• Snap-on installation for replacing missing or broken trim
• No electrical or network connection involved

Compatibility and fit

Confirm your chartplotter model before ordering, since similar trim pieces exist for other GPSMAP screen sizes. This part is intended for the GPSMAP 8x24 footprint, where the trim runs along the helm opening around the display.

If your unit is bracket-mounted or uses a different dash cutout style, verify that you have a glass-helm style installation where snap-in trim pieces are used.

Installation and setup

Clean the mounting area first so the trim seats evenly. Line the piece up with the edge of the display opening and press along the length until it snaps in and sits flush.

When removing, work slowly from one end and avoid bending the piece sharply. Taking your time helps keep the trim aligned and avoids stress marks.

Use cases on board

This trim piece is most common on boats with a glass helm that runs multiple displays side-by-side, where any missing trim stands out right away. It is also useful after a display swap or dash work where small trim parts can get lost.

It is a good match for owners replacing a missing trim section around a GPSMAP 8424 or 8624 to restore a clean finish at the helm.

Maintenance and care

Rinse with fresh water after washdowns and wipe with a soft cloth. If you need soap, use a mild cleaner and avoid abrasive pads that can haze the surface.
