Yeah, but I still like the integration of the NAV with Bluetooth so you can call up businesses you search. I also like the bigger screen, nag traffic and the weather and weather alerts for not only your current location, but your destination too. Not to mention the larger screen for the backup camera. I think the internal hard drive (to store all your music) comes with the NAV.
In addition to storing your music library, you can timeshift (pause, FF, REW) live music, and record up to 90 min of programming after you turn the car off.
