I don’t have the car anymore but I eventually went to the junkyard and sourced a new Sony headunit from the junkyard to swap in. I got one with navigation which was a nice bonus.I have the same problem... Anyone found a fix for this? The only buttons that work on the Sony control panel are door lock and hazard flashers...Did you find a fix for this? The same thing happened to me 2 days ago on my 2012 SEL. Usually this happens every few weeks but it restarts itself after an hour. It's been 2 days and it's still black. I pulled the battery, pulled and checked the fuses and everything is fine. The entire control system for the Sony system doesn't even light up anymore (Power, Eject, Source, Sound button, etc.).
