You just select the Navigation option on the app screen and it brings up a map of sorts. Then you key in the address at the top in the address bar and it brings up a popup with the location that you select and that takes you to a screen where you select to send the directions to your NAV or Turn by Turn. When it responds with directions have been sent, you are done. Then when you start you car, the directions are downloaded to your Nav, if you selected to send them to it.
