MediaNav 4.1.0 - rear camera activation

Hi,
I do not know is this adequite place to search, although I would ask for help.
I would like to activate rear view camera on Captur which has MediaNav 4.1.0
With regard to that, what do I need to do in order to make it operational? I forget to tell that I connected all the components as rear view camera, cables, adapters and it works with spare aftermarket display but does not with OEM display.

Just install mena.co and follow the install guide here:
