I don't have a nav unit, (but my road atlas is in English).

Seriously though, as we know the left and right wiper arms are different lengths and shapes, and my drivers side wiper arm looked like it was identical to RickZ's driver side wiper, only mine didn't have the airfoil on it.
At first I thought they simply got em mixed up, but they seem to be the correct arms for there location.
I was just wondering if anybody else (who had a left hand drive XF) had the airfoil on the passenger side like mine does.
