I was given this dashcam as a gift and can't get it to change modes. It's stuck in the single frame picture mode and does no good as a dashcam. I tried using the buttons as indicated in the instructions but it still won't work. It turns on and off as it should when the ignition is turned on and off but stays in the steady yellow mode. The instructions state it must be turned to a flashing yellow to indicate it's recording. No can do.
