When in Quick Drive, place your mouse over the top left of screen and a series of drop down buttons will appear. Hit the one with the question mark (“On Screen Help”). The arrows plus junction name will appear, as will some other help details.
If you don’t like seeing this permanently (it does look a bit cluttered), leave the “On Screen Help” unchecked and simply run you mouse over the junction. The arrow and junction details will then only show for activation as you choose.
