Here in some parts of Brussels, the Nav does not take one way streets into account. As a consequence, I found myself in a very embarrassing situation taking a narrow street in the wrong direction. That was on day ONE when I was not used at all of the width of the MS, which is rather unusual in Europe. My iPhone got it right though. I thought it was just one glitch or mapping error, but no, today it insisted very much to have me take impossible directions in places where traffic has not changed in decades... The car may come from the future, but its nav system is from very long ago.
