The system pairs the driver's iPhone with the car's infotainment system and seamlessly allows them use the smart phone's functions and, at least in Volvo's demonstration, the car's climate control and seat heating systems. According to the video, the new system will be available "in the coming generation Volvo cars," which likely means the upcoming, next-generation Volvo XC90.
However, the system will not work universally. Apple will add functionality through an update to iOS 7 in the future for the iPhone 5, 5C and 5S. At launch other devices won't be supported.
