Hey guys, got a 05.5 A4 with NAV. I ejected the NAV DVD and popped in a DVD+R. I get Disc unreadable and the system just freezes up, I can't eject the DVD and the screen stays down, i am unable to put it up. After leaving the car off for 5-10 mins, turning the car on will raise the screen back up but the system will freeze if i try to eject/select the NAV. Any ways to force this DVD out? Trying to save myself a trip to a dealer.
