The subject is a Citroen Jumpy 2007-2016.
Because it's a van, it was possible do order it without any factory radio, but with the regular small monochrome display. In this scenario, there are 3 buttons beside the lcd to control it. Picture attached.
I would like to retrofit this, but I can't seem to find any oem number for the parts or diagram about its wiring...
If you could be any help with this...
UPDATE: I found the wiring diagram for it. Now Im only looking for the lcd frame oem number
