Also, my phone follows me between vehicles and provides the exact same interface in all of them. Heck, I can switch vehicles and my podcast or music starts back up right where I left it. That alone is a major win for the phone-based approach - if I drive my spouse's vehicle for instance, or my old truck because I need to haul something, doesn't matter, they all have the same navigation and audio.
