I'm aware there are two computers and the UI crashing has no impact on the basic function of the car, but turning the car off and on makes the media computer restart. Not sure if he was aware about the steering wheel reset function, it was a while ago that he told me that story. Also possible I've misremembered it.
I should not have said 'this is false'; the story very well could be accurate. Please pardon the harsh tone.
It's more correct to say that stopping and re-starting the whole car is not the easiest way to restart the MMU. It's quite possible there are people who aren't aware of the 'two thumb salute' method.
