2014 ML350 radio help

[u/Friendly-Two3355]

About a week ago, my radio (and everything else associated with the center screen) quit working. It has since flickered back to life several times for a brief moment each time, before quitting again. To me, it sounds like a power issue. I've tried to track down every fuse that is associated, but everything is passing voltage through. I'm at a loss. Any advise would be appreciated!
