I've translated your French into English using Google Translate
You will get the best responses by posting in English if you can. Google Translate is not bad as an assistant. The forum is very much biased towards the USA and English is usually expected on posts. If the car is running OK it does look as if you have a problem with one of the electronics modules, (or the links to them), that support the in-car entertainment, satnav user screen.

 

hello, yes the rest of the car everything works no worries really only the multimedia part but impossible to find I'm starting to get tired from looking

 

Had this once, it was a weak battery. Reconditioning it with my Ctek did solve the issue.

 

thank you, I have just tried but still the same I have music for 5 seconds and finish nothing more or camera, radio and gps. if the amplifier part that is in the trunk is defective, does it cut off all the multimedia, even the camera and gps? because the amplifier turns on and off at the same time or everything crashes? thank you in advance
