Navigating with the driving directions
Now that StreetMap has generated driving directions for you, you can follow the instructions on this page for navigating with them.
Tap on the numbered line of the driving directions that you would like to see on the map. StreetMap zooms to that portion of the map.
Full screen or 1/3 screen in options: To change your driving directions so that they fill either the entire screen or only 1/3 of the screen, tap the StreetMap Preferences button. In the Routing Options tab, tap either 1/3 or Full Screen for the Route Summary.
Increasing/Decreasing font size in options: You can increase or decrease the font size of the driving directions. Tap the StreetMap Preferences button and select the font size in the Routing Options tab.
