CarPlay will show up as an update to iOS 7 for the iPhone 5 and later models. Once connected via Lightning cable, drivers can use Siri to receive and send messages, use a dashboard touch-screen to interact with apps, or pull up directions via Maps.
Some third-party apps will also work with CarPlay, such as Spotify and iHeartRadio, but it seems apparent other apps will become compatible down the road. Other auto manufacturers, including General Motors, Ford, and Toyota will also feature CarPlay in future vehicles. Strangely, it appears Chrysler is the only major auto manufacturer not on the list.
