@Jean-Pierre LOTHAIRE Hi customer, we are wondering if you could try to factory reset the system to check if the zlink could work after then. In the meanwhile, please send us your order number so that we could record.
Bonjour, voici mon numéro de commande: 
@Jean-Pierre LOTHAIRE Hi, have you factory reset the head unit yet? If the problem persist, please go to Settings > About Machine and send us the currect Build Number and MCU version.
In the meanwhile, please go to Car > Factory settings > enter 126 > Apps > enable Carplay to check if it could improve the situation.
