2012 A8 just had blank mmi screen . Don’t know why or what caused it . Everything was workinh fine this morning until I got in car to go to work . And all I seen was blank screen not even one flicker. Radio and xm is playing . I even tried reset mmi. No luck. I did a wiggle check to see if screen would flicker or come back up and still no results. I tried to access navigation from steering to see would it still function and it was saying navigation not active or something of them words. Anyone on here have a solution. I am thinking of taking radio out to see if it’s plug or wire issue from the motorized function constantly going up n down. Any solution to help me would be greatly appreciated
