The reversing camera on my 2013 HSE Black Edn has developed too wide a view from which shows the whole of the back window, the wiper and even a bit of the underside of the spoiler. The yellow lines are still there but now start on the window and the image is the right way round. Previously I could see the rear bumper.

I've checked the mount and everything looks ok. Does anyone know if the image is adjustable or whether it is the first sign that the camera is on its way out?
