Overview

The Garmin 010-12445-21 is a replacement microSD card door made to close and protect the memory card slot on echoMAP CHIRP 7Xdv and 7Xsv units. It is the door only, not a memory card.

If the original door is missing, cracked, or no longer stays shut, the card slot is left exposed during washdowns and rough runs. Replacing the door helps keep your chart or update card seated and reduces the chances of moisture or grit getting into the slot area.

Key features

• Fits echoMAP CHIRP 7Xdv and echoMAP CHIRP 7Xsv units
• Covers the microSD opening so the card stays held in place during vibration and pounding
• Helps keep spray and debris away from the card contacts when the door is closed
• Restores quick access for chart cards, software updates, and data transfer without leaving the slot exposed
• Replacement door that matches the original fit on the unit

Compatibility and fit

This door is specific to echoMAP CHIRP 7Xdv and echoMAP CHIRP 7Xsv models. If your unit is a different echoMAP generation or screen size, the door style and attachment points can be different, so match the model name on the unit before ordering.

Installation and setup

Replacement is a straightforward swap of the existing door on the unit. Work in a dry spot at the dock, keep the card slot area clean, and avoid forcing the door into place if something does not line up. Once installed, close the door fully before powering up and heading out.

Maintenance and care

After saltwater use, a light rinse around the unit and a wipe-down helps keep salt crystals from building up near the door edges. Any time you open the door to change cards, keep spray off the opening and make sure the door closes flush again before the next run.

Use on board

This is a good match for boaters who regularly swap chart cards or run software updates and want the microSD access point properly covered again. It also makes sense for open helms and center consoles where the electronics see more sun, spray, and washdowns.
