If the exit on the highway is like 85C, SD will say "Turn right onto 85 degrees Centigrade".

Also, i dont know if this bug was ever fixed but i did notice it in 1.1.1.0:

If the route that you're taking is long (i.e. more than 1000 miles), the area that says how long left on the particular road, the text in that area will actually collide over surrounding text due to the number being 4 digits.
