Very strange. I got notice this afternoon I had a firmware update waiting to install. When I got home I told it to Install Now. When I went out to the garage a few minutes later to do something, the radio was playing and the dc charging ports were live. But the screens were both blank and unresponsive. I tried to turn off the music with the scroll wheel, but no response. Never had this happen with any other update. A minute or two later, the radio turned off.
