Hello, I recently bought the opia 2 by vicovation from an australian supplier. I've plugged it into two different cars with the OEM cigarette charger however the dash cam doesn't turn on at all. I tested it on my pc afterwards with a usb to mini usb cable, and the dash cam light does turn green but the screen is black. So I'm not completely sure if it is the cable supplied that was faulty or if it was the dash cam. Has anyone else had trouble like this, I cannot find any other forum posts with similar problems.
