No matter what I do I can't get my 7" Digital Dash to update to the V5 firmware. It's brand new and came with the V4 version installed, so I have never had to update it before. Is there any other way to update the firmware besides a USB stick? Tried using the USB stick that was included with the dash and another generic stick both with same result. I tried by keying on, and also by trying to manually do it from the Configuration menu on screen. The dash just restarts and gives me the same error of mismatched versions every time. Was wondering if it can be done via laptop?
