CarPlay will be available as an update to iOS 7. But as CNET's Tim Stevens points out, cars themselves won't be running iOS; instead, they'll be receiving a signal from the handsets -- the iPhone 5, 5C, and 5S -- when they're connected to the car via Lightning cable. Drivers will be able to use CarPlay either with fingers on the touch screen or by speaking out loud to the Siri software.
Maps a la CarPlay
CarPlay will be available in "select cars" shipping in 2014, according to Apple, from automakers Ferrari, Honda, Hyundai, Jaguar, Mercedes-Benz, and Volvo. At this week's Geneva Motor Show, we'll all get a look at some CarPlay-equipped models from Ferrari, Mercedes, and Volvo.
