Apple CarPlay 

is a feature that allows you to connect your iPhone to your car's infotainment system, allowing you to access certain apps and features of your phone while you are driving. With CarPlay, you can make phone calls, send and receive text messages, listen to music, and get directions, all through the car's display and audio system. To use CarPlay, you need a car that is compatible with the feature and an iPhone that is running iOS 7.1 or later. Once you have these things, you can connect your iPhone to your car using a USB cable and then select the CarPlay option on your car's display to access the features.
