Setup, Compatibility & Care
To ensure optimal performance, insert the card into your 70mai dash cam while the device is powered off. Once inserted, it is highly recommended to perform a format operation through the dash cam's internal menu settings to align the card's file system with the camera's requirements. Keep the card contacts clean and avoid exposing them to static electricity or physical bending. If you need to transfer footage to a computer, use an SD card adapter and ensure you use a safe ejection method from your computer's operating system to prevent file corruption. Periodic re-formatting every few months is considered best practice for long-term reliability.
