The dash cam requires a stable power supply to boot up. Please verify that the power connection is secure (use the original car charger included in the package).
Check whether the power cable connector is loose at the dash cam port.
If the issue persists, contact our after-sales support team for assistance.
Disconnect the power supply, restart the device, and check whether the function is restored.
Try replacing the SD card with a new one, or format the existing card (compatible with CLASS 10 U1 SD cards, 8GB–256GB capacity).
If the problem remains unresolved, contact customer service immediately.
1. Check that the dash cam is powered on and its Wi-Fi function is enabled (the Wi-Fi indicator light is on).
