Is Much more advanced than before. A lof of changes I like, I usually like typing address when I drive, but the new car doesn't allow me to do it.:) also, I can listen satellite tv in the car, but I don.t use it. The bluetooth itself keep me busy enough. The most important is the emergency call, even I drive to a place there is no signal, that will connect me with the center of Lexus emergency help based on Florida.
The factory installed Gps much better than Whatever you get for individual setup later on.
