Let's add another route pin.  On this trip our next stop is the Golden Gate Bridge.

Any easy way to quickly move to a location on the map is to tap the Find button.

Start typing the location you want to go to, and as soon as it appears in the list, tap the name.  In this example we tapped Golden Gate Bridge.

The map now shows to the Golden Gate Bridge.  We see on the map where out next location should be, so we tap the map and hold for about 1 second.  A new route map pin is created.
