On the road: Optional City Navigator mapping provides detailed street maps, millions of preloaded points of interest and onscreen turn-by-turn directions to your destination, and an optional Auto Nav kit adds a suction mount and car charger.
Mapping nearby features, spotting road edges and lane markings, reading signs and traffic lights and identifying pedestrians is done using a combination of cameras, radar and lidar (which works like radar, but with pulses of light rather than radio waves).
