Hello, I am also in the same situation but for a C4 Picasso II. The Picasso foresees the use of the rear camera 180 (98 067 941 80) only if combined with the Vision 360 system. Comparing the wiring diagrams I noticed that the pinouts of my 130 (98 011 465 80) are practically the same as those of the 180 camera of the Peugeot 308 (98 093 010 80) but different from those of the Picasso with 360 system. So I thought I would enable the Vision 360 system on NAC and select in the options only the display of the rear camera 180. Could it work? I attach the diagrams.
