Forums Forums K3 Dashcam Empty video files

  • Empty video files

    Hello,

    I bought a motorcycle that already had the K3 dash cams installed, without memory card.

    I then bought a 256GB, V10, U1 memory card, according to the user manual. It’s FAT32 formatted.

    Now, the green camera symbol is flashing slowly all the time, and when I try to record a video, by pushing the button, it does save a file, but the video files are all 0 kB and my computer says they are wrong.

    I also tried a FW update, but I’m unsure if it’s succesfull and it didn’t solve my issue.

    What could be wrong?

    Browsing the forum just now, I saw someone mentioning U3 as minimum for the memory card, but the user manual says U1.

    Grts,

    Gijs.

    Hi Gijs,
    U1 is sufficient, U3 is better (is faster). But besides the U-number, the video speed class mark is also important.
    Have you already formatted the SD card using the Innovv app? It is recommended to format the SD card with the app and not with a computer.
    In the app, do you see that the cameras are working properly?
    If the firmware update went well, you can see in the app under settings which firmware the K3 has. This is under System. To be sure, you could perform the firmware update again if you have any doubts.
