Let's work on mounting the camera now.
This is what the camera looks like mounted.
But first, we need to remove all of the covers on the hatch to work on it.
Start by gentally pulling on the edge of the top center piece. It should snap off quite easily.
Next, remove the side covers. Just pull on it, it will just snap off.
Note, there were once screw on each side under the side covers. Remove these screws to free the main hatch cover. Pull on the main hatch cover and it should come free as you work it all around the cover.
With all of the covers off, we can work on mounting the camera.
