Was driving car yesterday and MMI screen froze up, screen went blank but radio stayed on (even when removing key and locking doors)! Had to remove 7.5 amp fuse to turn radio off! Have now re-fitted 7.5amp fuse but all is dead. No screen display and no lighting on switches around gear shifter. I have checked all fuses located in Left & Right dash and Boot and they are all fine. I am also able to eject & load CD's in head unit.
Car is 2009 B8 MMI 2.
Anyones help would be gratefully appreciated
