Rear camera view got tweaked?

winnre

I admint I only use the rear camera when backing up pretty much, so it's not like I can tell you all that I see on the nav screen as a result. But yesterday I thought I noticed that the camera got tweaked.

The view on the nav screen includes the license place from above, and the lower left corner of the image is snipped off. I went back to thwe camera to see what I could see, and found that the lower left part of the image snipped off is because the camera is recessed and the bumper blocks that area a little bit. Seeing the license plate from above is interesting - that is on very closer camera. I tried to wiggle the camera and it was definite not going anywhere sp that was not the issue.

Is the camera I tried to wiggle the entire camera or just the housing?
Is what I am seeing the correct view? Is there a way to calibrate it?
