General engine fuse pannel

[Campogr]

I have a 2016 panda cross diesel 4 x 4. The air con doesn't put out cold air ever since I installed a new media center in my radio slot 3 days ago. The only other issue is that the temp read out doesn't work anymore. I was wondering if this has any control over the air con.
I have tried to find a engine fuse diagram but everyone I see is not like mine. ie air con climate control f19. No such fuse in the panel, at least not where is shows on the diagram. In my 19 slot is a large red fuse but the diagram shows a small one. My panel is FULL of fuses but All the diagrams show only a few.
Any help is greatly appreciated especially since summer is around the corner.

Hi!
I think you damaged something while installing the new media center. this could be the wire leading to the air con and temperature sensor or connectors

You may have diconnected the thermostat hence no display. Im not sure where but its pretty sure something has been disconnected or broken during operations.
