No SD Card

How to Fix It

1. Check whether a card is installed and is the right size

   Remove the BlackVue from its windshield mount and inspect the SD card slot (typically at the rear of the camera body, sometimes behind a small cover). BlackVue cameras use microSD cards — ensure you have the correct format. A standard SD card or no card inserted will cause this message.

2. Remove and firmly reinsert the microSD card

   Push the card gently into the slot until you feel a click. BlackVue slots use a push-in push-out mechanism. If the card was only partially inserted, a firm push will seat it. After reinsertion, power the camera on and check whether No SD Card is still displayed.

3. Clean the card's gold contacts with a dry cloth or eraser

   Remove the card and gently rub its gold contact strip with a dry lint-free cloth or the side of a pencil eraser. Oxidised contacts can prevent detection. Blow any dust from the card slot before reinserting the cleaned card.

4. Test with a different known-working microSD card

   Insert a different microSD card (even a spare from a phone) to determine whether the problem is the card or the camera's slot. If a different card is detected and the error clears, your original card is damaged or incompatible. Replace it with a high-endurance card.

5. Contact BlackVue support if the slot itself is damaged

   If no card is detected regardless of which card is inserted, the card slot contacts inside the camera may be bent or the slot reader has failed. This requires service. Contact BlackVue support (or your point of purchase) for warranty repair or replacement, as the camera cannot function without a working SD slot.
