Hi. Yesterday i was driving my 2014 gl450 everything worked fine from the 360 camera to the cd player while I was driving to my destination and as i pulled into the parking lot the command screen booted a couple times showed the warning that says not to look at the navigation while driving then went black I turned the car off and left when i came back and turned on the car the command screen in the middle did not work at all neither did the cd player it was all blank i also got the blind spot monitoring inoperative warning the heated seat buttons and the climate control works fine and the car drives normally too. I live about 200 miles away from the closest Mercedes dealer so that is not really an option for me unless its very very important.
