If you use pushpins to construct a route, you can edit how the Stops are presented in the Driving Directions and, therefore, the Navigation pane. Any changes you make to the Name field of the pushpin used as a navigation stop will be reflected in stop details of the route. This could include time, address, or telephone number, for instance.

So, let's say you have a set of pushpins that you want to convert to stops for which a route will be constructed. Go to the pushpin set in the Legend and overview pane and right-click and then click on Add pushpins as stops and calculate the route. Now with "show all pushpin information" on for the set, you can follow the route and edit the names of each pushpin by clicking on the name field in the pushpin balloon. Note that you can do this right on the map without going back into the pushpin set.

For instance, you could insert a projected arrival time ("4:47 PM Smith House") so that the navigation pane would show that (or Anna would speak it). Or you could put the street address in the Name field. In this way, you would not have to change back from Navigation mode to Driving Directions to see how you are doing on time or to look up the address of your stop.

Also, you could correct abbreviations. If you have time data in the name line of the pushpin and it is before noon, it will say something like "10 14 am" as in "I am tall"). So, you might want to change the "am" to "eh-em" so that Anna reads it the way letters are pronounced (she handles PM just fine). You could also change "RD" (which will sound like "ardy") to "are-dee", etc.

Of course, you can get the same result by renaming the Stops in the Route Planner pane.
