W211 Headunit Malfunctioning
I have a 2008 E350 and had the logo on the screen when it starts up change to show amg. I tried to change it back to the original because I've had it like that for like an year and when I did the screen wouldn't show anything on it besides the hazard sign from the warning message when you start the car. Anybody have any idea what's happening? I already disconnected and reconnected the battery.
