What is "carplay"

CarPlay is an Apple standard that enables a car radio or head unit to be a display and controller for an iPhone. It is available on all iPhones from the iPhone 5 with at least iOS 7.1.

Most worldwide vehicle manufacturers have said they will be incorporating CarPlay into their infotainment systems over time. CarPlay can also be retrofitted to most vehicles with aftermarket vehicle audio hardware.

According to Apple's website, all major vehicle manufacturers are partnering with CarPlay.
