Backup Camera, not intended to be controllable, zoomed by itself

I have a 2012 Chrysler 300 AWD. Maybe caused when helpful friend slammed trunk lid. Former narrow view was ideal for backing into parking space. Could come within one inch of the car behind without ever touching bumpers. Now an extremely wide view, pictorially attractive but useless. If I loosen the fabric on the trunk lid interior, I hope I will access a manually zoomable lens. Yes? No?
