I HAVE INSTALLED A CHINESE MM ANDROID STATION WITH THE STABLE SCREEN. MY CAR IS AN A3 TDI ULTRA YEAR 2015. THE MM STATION COMPATIBILITY WORKS PERFECT AND THE APPS ALSO. THE ISSUE IS THAT... SAME RANDOM TIMES.. (ONCE A MONTH OR LONGER )ONLY WHEN I TURN THE IGNITION ON AFTER PARKING TIME THE MMI GOES OFF ..BLACK DISPLAY SCREEN....BLACK MMI CONSOLE LIGHTS...ONLY SOUND FROM THE APP WAS ON (RADIO,MEDIA)... NOT BUTTON RESPONCE.. MY BATTERY IS GOOD...THE FUSES ARE OK... THE PROBLEM IS FIXED ONLY WHEN I PULL OFF AND ON THE NEGATIVE POLE OF BATTERY. UNTIL NEXT TIME FAIL. ANY IDEAS PLEASE ??
