Android Auto is a mobile app developed by Google to mirror features from an Android device, such as a smartphone, to a car's compatible in-dash information and entertainment head unit. The system mirrors qualified apps from the device to the vehicle's display, with a simple, driver-friendly user interface. Supported apps include GPS mapping/navigation, music playback, SMS, telephone, and web search. The system supports both touchscreen and button-controlled head unit displays, although hands-free operation through voice commands is encouraged to minimise driving distraction.
