How to Fix Garmin Dash Cam 'Memory Card Degraded' or 'Card Error' Message
Quick Shortcut: When a Garmin Dash Cam displays 'Memory Card Degraded' or 'Replace Memory Card', it means the card's flash memory cells have worn out from continuous loop recording. Formatting the old card only clears the warning temporarily—replace it with a SanDisk High Endurance or MAX Endurance card.
Why Garmin Dash Cams Show 'Memory Card Degraded'
- 1. Garmin Dash Cams actively monitor write-speed latency and bad blocks on your microSD card. Standard non-endurance cards (like regular SanDisk Ultra cards) wear out quickly when overwritten in a hot car windscreen.
- 2. Switch to a SanDisk High Endurance or SanDisk MAX Endurance microSD card (64GB, 128GB, or 256GB, U3 / V30 rated).
- 3. Insert the new card into your Garmin Dash Cam and select 'Format' when prompted on the dashcam screen (or inside the Garmin Drive phone app for Mini 2 / Mini 3).
