The map screen shows the physical location of stops.
You can get to the map from the Quick Treks screen after locating nearby stops so you can see where they are relative to you.
If the transit system in question supports it, stops can be plotted on the map to show their exact location and are represented by stop markers.
Inactive Stop Markers
When you tap an inactive stop marker, the map centers on that stop and a popup window shows the transit system the stop is for, the stop's name, and all the routes that serve that stop.
