So recently I was having issues with with the command display/screen. Well it went completely black and won’t turn on. The buttons on the middle console neither work or light up and the command unit itself doesn’t light up either. What’s odd is that I brought the command unit to play who tested it and it worked fine no issues. I checked all the associated fuses for the command unit and all them are good. I even swapped out them for new ones still nothing. When I use Mercedes star to scan the rear sam all the fuses I get the picture below on all the fuses. Front Sam I don’t get these errors at all. I even went as to swap out the rear sam and had it coded and still I get this error. Anyone want to shade some light on this please cause I am losing my mind. The amp was checked and is good as well as I said the command/dvd player itself. The only other 2 components to replace right now is command screen/display and the buttons on the middle console..

Late at night for me...I recommend jumpering (bypassing) modules out of the MOST ring as that could be killing your audio system. MOST ring ties into the CANBUS net but is separate from the CANBUS. I hope that makes sense. I'll look more once I get some sleep...

I will try but I noticed that my fiber optic cable isn’t flashing on the plug going into the command unit.
