That's happened to me before but the screen went back to normal after about 10 minutes. Not sure what happened but I was driving on the freeway and by the time I was able to exit and pull over, the screen went back to normal.I wish it was that simpleI do not plug in with a cord, I have the built-in wireless charger but even when I just have my phone unconnected and propped up I lose connectivity. I was out showing houses today and my screen just went black in the middle of navigating in a busy Minneapolis area plus I was on the phone and although the connection to the phone was still there it was no longer going through car play, very distracting.
