Nav Launcher has all the same important features as the default Navigation launcher app, such as:

-Quick access to contacts, starred contacts, and favorites-Easy entry of a typed or spoken address-A history of where you've gone before

However, Nav Launcher makes it easier to access all of these, and allows you to set two Quick Favorites, for frequent destinations (such as "Home" or "Work").

If you always want a certain screen to start up (such as Contacts, Favorites, or History), then you can customize it to do exactly that! Nav Launcher can even launch itself whenever you place your phone in a car dock.
