Nope, I haven't finished this project yet. I installed the 180 camera, here is the result on 508 SW:
I'm stuck on one thing: the 3rd photo, ZOOM view, the rear of the vehicle protrudes from the frame. I can't find a way for that. I tried just by changing the model to a 3008, 5008 or 308 and these are well in the frame.
I bought a second 180 camera, hoping that with visiopark2 the problem might not arise but I really don't have too much hope on that. On the other hand, the camera comes from a DS7, the same one on which I took the Visiopark2 box, however the connector is different (6 pins and not 4). Couldn't find the original connector, and the trunk harness was already gone when the camera was removed..
