Hello everyone

When I press the Push to Talk button on the multifunction steering wheel, the central display shows: BUTTON WITHOUT FUNCTION !

It worked before. Pressing PTT, you could hear the beep and the interactive voice system said: Please ...

Can you tell me what is no longer working?
What happened ?

Thank you in advance
