Your vin should be WDD2040081A259355 if yes, you do not have external amp, so mosh likely your internal amp is broken.

Hi
Thank's for your response
This radio work with internal amplifier and used TDA7563,I already replaced with a new one.
I installed the radio, began to work perfectly but when I start the car or the radio off and on again the same thing ,no sound as on video I posted in first post.
This is an interesting defect, I had not had the opportunity to face with something like this before.
So I would like to someone who had experience with something like this to share with us the solution.
I wish all the best!

Do you have latest software in COMAND (head unit software, not navigation one) and correct coding as well?

If the radio is cutting off and on only when the engine is running maybe your system voltage is too HIGH!! Is the alternator malfunctioning?
