Steering Wheel Controls.
Now I just had a chance to play with a 16 Hard Rock with the 430N and the Alpine system this weekend. It was pretty sweet.
Other than the integration into the driver's dash, I still think my Pioneer AVH4100NEX with an amp was better sounding but it was close. Android Auto or Car Play integration would be the only thing missing from the factory setup if that's important to you. And of course, Google maps is way more up to date than the Chrysler NAV package for the map database.
I see that in my 8.4N in the WK2. I have the latest map DB and it's 2 years out of date.
