After stopping the engine, a notice popped up on the info display. Choice to install now or later. I was away from my home wifi the first time, so I waited until I was connected to the home wifi. It gave some alerts about locking doors raising windows and that during the update, the car cannot be operated. It also said it can be left alone for completion, which I did. I came back when done and started the car. The only thing displayed was that the update was completed.
