You are most welcome… On SD cards… The V3 will take larger cards now, however there is some discussion in the threads right now on the ability for the cam to use the full capacity on cards over 128GB.
Also, your SD card capacity \ video age will be lengthened considerably if you reduce the video quality from HD to SD.
Recommend you get a very high quality high endurance SD card specifically designed for continual recording in a security cam or dashcam.
