1. Check the Card's Condition

• Make sure you have the right card: Use a genuine, high-speed card (like a Class 10 U3 or better) as recommended in your user manual.
• Inspect for damage: Look for any physical cracks, scratches, or bent parts on the card itself.
• Test the speed: You can use a computer tool to check the write speed. If it's consistently slower than 10MB/s, you should get a new card.
• Check if it's locked: If the card becomes "read-only" (meaning you can't format it or delete files), it's damaged and needs to be replaced.

2. How to Format and Repair

First, try to format the card using the dash cam's settings menu.

If that doesn't work, you can try formatting it on your computer:

• Use a card reader to connect the memory card to your computer.
• For cards 32GB or smaller: Choose the FAT32 file system.
• For cards larger than 32GB: Choose the exFAT file system.

Important: Both formatting methods will erase everything on the card. Back up any important files you need before you start.

3. Optimize Your Settings

• Turn on Loop Recording: Make sure the "Loop Recording" function is enabled. This prevents the card from getting full and causing errors.
• Adjust Resolution: 4K video requires a very fast card. If your card isn't fast enough, lower the recording resolution to 1080P.

4. Hardware Maintenance

• Clean the card slot: Use a cotton swab with rubbing alcohol to gently clean the metal contacts inside the card slot. This can fix connection issues.
