Routes allows you to view the Routes submenu. See Introduction to

The Routes Submenu contains the following menu options:
Create allows you to create a new route from an empty route, name
it, and add saved waypoints to it immediately. You can also change
the waypoint order of the route from this menu.
Edit allows you to select a saved route and change its name and the
waypoints in it.
Delete allows you to delete a route from the saved routes list.
Travel allows you to choose a route from the saved routes list and
use it as your current route. Routes can be traveled in either the
forward or reverse direction. When you select a route, navigation
begins immediately.
Info provides information about the route you choose from the saved
routes list, including the distance and bearing from each waypoint to
the next.
