About the Transportation
Modes
Automobile
Pedestrian
Bicycle
Your device has different
transportation modes for navigation.
Routing is calculated differently
based on your mode. For example,
in Pedestrian transportation mode
with cityXplorer ™ maps loaded, your
device calculates a route that uses a
combination of public transit options,
such as riding a bus or subway, and
walking. cityXplorer maps are not
included with your device.
