Why user should use genuine memory card.
Every memory card from each manufacture has different NAND flash and
internal controller. Our genuine memory card has been tested for long time
in multiple test environments. Also, genuine memory card shows the best
compatibility with our products. Memory card is very important storage
device and must have solidity to endure reading / writing data in every few
seconds during operation. If you use dash cam with other brand memory
card, we cannot guarantee proper working and warranty service.
Keep repeating Voice from camera.
If you have a problem with keeping repeating voice guidance, you need to
check SD card whether it is faulty our not. So, take out memory card and
insert onto PC to format SD card. For safety of device, user should check
memory card every two weeks.
