Your photos show the dashboard monitor, not the camera. If the monitor is coming out of the dash opening, you'll have to see behind the dash to find out how it's fastened. You might have access from underneath, or check to see if the top of the dash has a lift-out panel to access behind the dash. You could also remove the stereo to gain access. You might poke a phone camera up behind the dash and take photos.
