The MMI is the pop up computer screen which displays all functions, controls, navigation and camera to the car. This just went out without any warning. I was told that it may cost as much as $3,000 to repair depending on which module that may need replaced. I guess I should feel grateful it was only a broken wire that somehow came loose however it still cost me $557.77 to repair this issue. I guess this must be a 18 carat gold wire or something.
