Update the firmware on your dash cam in order to use 256gb micro SD cardReviewed in the United States on January 29, 2020
At first it didn’t work for my Vantrue N2 Pro. I had to look up and go to the website and found out I had to upgrade the firmware in order to use 256gb. They recommend putting it on a 8-64gb and I downloaded it and dragged it onto the 256gb. Hooked it up to my Vantrue N2 pro and it updated and was able to use the 256gb micro as card.
