Show curvy roads on the map
Tap the Map Settings icon on the map and turn on Curvy Roads under Map Details. The Curvy Roads layer is part of Premium.
The Curvy Roads layer highlights curvy roads on the map, so you can spot the twistiest roads at a glance without zooming in on every turn.

Turn the layer on or off
With Premium, the layer is on from the start. To turn it on or off:
-
On the map, tap the Map Settings icon, the cog in the top right corner.

-
Under Map Details, tap Curvy Roads. The same section has Places, road segments and Favorites.
