Some news about my story :
Just picked up the car and it seems that they never arrived to code the new IKE, because there is a problem with the Light modul on the left (not the LCM) So maybe that's because it wasn't any audio/video, the ibus was stuck ?
On the retrofit manual for high IKE, there is no need to change any modul more ???
I don"t think they really know wat there're doing...
