Do you mean that you can have the "map" on CONSTANTLY while driving, even if you don't put in an address? So when you turn the car on, the map is already up?

Yes, we always have the Nav system on. If an address is not selected, then I set the screen to show gas milage and other things. You can also select a split screen with map on the left and other things on the right. It also shows the radio station.
