• How do I connect my 70mai dash cam to the mobile app?

  Download the 70mai app from the App Store or Google Play. Enable the Wi-Fi hotspot on your dash cam, then use the app to search for and connect to the dash cam's Wi-Fi network using the password displayed on the screen.

• What type of memory card should I use with 70mai cameras?

  Most 70mai dash cams require a microSD card with a capacity between 32GB and 128GB (up to 512GB for newer 4K models). A Class 10, U1, or U3 rating is required for reliable recording. Format the card inside the camera before first use.

• Why is my rear camera not being detected?

  Ensure the rear camera cable is securely plugged into the main unit's rear port. 70mai recommends using only official 70mai rear cameras to ensure compatibility and prevent malfunction.

• How do I update the firmware on my device?

  Connect your dash cam to the 70mai app. If a firmware update is available, the app will prompt you to download and push the update package to the camera.

• What should I do if the dash cam stops recording?

  Check if the memory card is full (though loop recording should handle this), corrupted, or too slow. Ensure the power cable is securely connected and the card is formatted correctly via the device settings.
