Qashqai J10 reverse lights do not turn on
 

Hi,
I have a Qashqai +2, J10, 1,6 Diesel, Manual gearbox
I checked the fuse, the R switch on the gearbox and the bulbs and all are good.
As an observation, when I put the gearbox in R, the video monitor in the cabin does not switch to the rear video camera. I don't know if it's supposed to do this, but I think had to switch to the front camera.
