My 64GB SD card was not recognized after upgrading to latest firmware. It's just recording a few minutes then the card was not recognized. Need to format and it happen again and again. The card is in good condition. already test at another brand of dash cam. 

Please advise.

Thank you

    Unfortunately, I have the same. After uploading new software (1.0.5na) I have a momentary message about not recognizing the card and the need for formatting. Formatting gives nothing, after a while again the same message. To make it more interesting, it does not display the speed or position on the screen.

    Unfortunately, at the moment the device is useless. After the message about not recognizing the card, I format it, after a few minutes the same message. Over and over again. I have already written a few times for 70mai technical support, but no response from them. The only thing they wrote to me is: "Hi there, the new firmware can test the defect of SD card.You can change a SD card of 16~64GB, class 10 and above".

    I returned to version 1.0.4 and everything is OK. I am waiting for a revised version 1.0.5 or 1.0.6
