You'll only get the animation if the car's electronics were fully asleep. If you leave the car in your garage unlocked at night, then the next morning open the door and start up the engine right away, you'll see it. If you lock your doors though, when you go to unlock them in the morning, the act of unlocking starts waking all the car's systems up. By the time you are sat and switch on the engine, the headunit is already booted and ready.
