Toggle between driving, public transit, walking, bicycling, or ridesharing using the icons placed right below your destination input.

Use the speaker icon situated at the top right of the map to toggle between full voice guidance, alerts-only (notifying you of speed traps or accidents), or complete mute.

Secondary route options appear as gray lines on your display. Simply tap a gray line to instantly switch your active path.

The top margin of the screen alerts you exactly which lane you need to be in well before an upcoming highway exit or turn.
