Android Auto AND Apple CarPlay In Select Production Cars
The first car to be sporting this brand spanking new software is the Hyundai Sonata with it's 8 inch resistive touchscreen.
The car's Audio Video Navigation(AVN) seems to be running both(maybe not in the same vehicle) of the custom "infotainment" systems as apps on top of the existing UI.
Both "infotainment" systems have the same core features:
"Eyes-Free" voice searching and commands
Make calls
Access messages
Music controls
Navigation controls
Siri/Google Now respectively
