Had notification for update on our 2017 100D Model X and started it. Went back in about an hour and both screens are blank / black. Can open the doors, but no screens and cannot drive the car. Tried rebooting both and nothing.
I saw the main screen do that this morning, even though I didn't receive the update upon this evening (thus, it was pre-most recent update - the App Frunk/Trunk update). It took at least 5 minutes for the main screen to wake. Never seen that before)
Although who knows, it may not be related to the update.
