Goedemiddag, weet iemand hoe ik de firmware v 7.21 terug kan zetten naar v 5.00.

De telefoon hikt wanneer iemand mij belt en achtergrond geluid meeneemt gesprek is dan bijna niet mogelijk.

Volgens de fabrikant van auto moet de software van de telefoon terug gezet worden is nu 7.21 moet naar v 5.00.
