ML350 Screen Stuck on Logo
my 2012 ML350 suddenly got some problems with it's dashboard screen. I drove the car in the morning, everything was fine. 2 hours later when I started my car, the dash screen won't start. It just goes blank. I hold the center button on volume knob to manually turn it on, and it just stuck on the Mercedes Benz Logo screen. Radio is working, I can adjust still adjust the volume and everything, the screen just dont show anything except for the logo. I turned it off and on again several times, still the same. Then there's a weird Japanese message showing on screen with "KEY OFF" (the only 2 English words in it).
Any suggestions? Is there a way to somehow reboot the system?
