I have a Audi A4 B8 Concert System with a MMI of course. Tried Hard Reseting this bastard while pressding down on SETUP + KNOB & top right hand side (even tried top left hand side button) Still no chance. I really need to reset, as my TEL option frozen. i cannot do anything withing the Tel app. BTW I have an IN-DASH Unit. Not the ordinary one next to the gears.
Please help me.
