The reason is that dashcams put microSD cards under higher stress than most electronic products such as action cameras or DSLRs due to their constant loop recording. Note that we recommend using BlackVue microSD cards for optimal performance. Note: compatibility is guaranteed only with the official BlackVue microSD cards. DR650S, DR650GW, DR490, DR490L, DR470, DR450, DR430 Series models support up to 128GB cards, and DR750LW-2CH supports up to 64GB cards.
Note: the X Series, DR900S, DR750S and DR590W Series models have a unique password included in the box and on the camera’s serial no. To connect using the BlackVue App, use the default password “blackvue“.
After firmware upgrade Wi-Fi login information will be reinitialized.After the firmware upgrade, please use the latest version of the BlackVue Viewer and/or App.If you format the card from the BlackVue Viewer, it will be formatted automatically in FAT32. The SD card must be formatted in FAT32 format.Please backup all necessary files before formatting the SD card, since all your videos will be erased in the process.
