Garmin Dash Cam 'Memory Card Error' — How to Fix It

What it means

Garmin shows 'Memory card error' (or 'There is a problem with the memory card') when it finds a card but can't read or write to it reliably.
Loop recording stops — so you're driving without a recording until it's sorted.
It's almost always the card, not the camera: corruption from a bad shutdown, a card that isn't rated for dash cam duty, or one that's simply worn out from constant rewriting.

Affected Models

Garmin Dash Cam 47 / 57 / 67W
Garmin Dash Cam Mini 2
Garmin Dash Cam Tandem
Garmin Dash Cam Live and X-series

Common Causes

Card filesystem corrupted by a sudden power loss while it was writing
Using a standard microSD instead of a high-endurance card — dash cams write nonstop and burn through ordinary cards fast
Card worn out after months of continuous loop recording
Card formatted on a PC with the wrong settings
Dust or a bent contact in the card slot

How to Fix It

Format the card in the camera.

Settings > Camera > Format Card, or do it from the Garmin Drive app.
This wipes everything on the card, so pull off any clips you want to keep first.
A clean in-camera format clears most 'memory card error' messages straight away.
Test the card in a computer.

If the error comes back, put the card in a PC card reader.
If the computer also struggles to read it or throws errors, the card is failing — replace it.
If the PC reads it fine, the format step above usually does the job; if not, the slot may be the issue.
Use a proper high-endurance card.

Garmin dash cams want at least a Class 10 / UHS-I U1 card; 4K models prefer U3.
Buy a high-endurance microSD — Garmin's own card, SanDisk High Endurance, or Samsung PRO Endurance.
A cheap standard card will throw this error within weeks because the camera rewrites it thousands of times a day.
Reseat the card.

Power the camera off, push the card in to release it, blow any dust out of the slot, and click it firmly back in.
A card that's worked slightly loose reads intermittently, which the camera reports as an error.
If a new card still errors, contact Garmin.

A brand-new, in-spec, high-endurance card that errors immediately points at the camera's card reader, not the card.
Contact Garmin support — if the unit's in warranty this is a repair or replacement.

Frequently Asked Questions

How often do dash cam memory cards wear out?

Far faster than the card in a phone or camera, because a dash cam rewrites the whole card over and over while you drive.
A standard card might last only a few months; a high-endurance card around one to two years of daily driving.
If 'memory card error' shows up more than once, just replace the card — cards are cheap, missed footage from a crash isn't.
