I have never seen it before..when switching. I wonder if this is a setting somewhere?I believe that is just the transition screen between any of the 4 upper screen buttons located across the center console dial. The buttons that read Nav, Phone, Info and Audio. It just comes up when you move from one screen to another but doesn't stay more than a few seconds.
Aha! It must a Canadian thing only. All forums users that see it live in Canada. I don't think it is on US models.ugpo is right, it comes up for a couple/few seconds when you press one of those 4 buttons. In the picture, the info button has been placed, leading to the trip computer, for example.
