Article: If you have a car stereo system that supports CarPlay, you can connect your iPhone to it and view Maps on the CarPlay display. Use the USB cable for your iPhone to connect it to the CarPlay unit. It may start automatically when you connect your iPhone, or you may need to select the "CarPlay" option on the display. This will start the CarPlay interface, and your iPhone will lock. Apple Maps will launch, showing your current location. This screen will allow you to search for specific destinations, find nearby businesses and locations, and view your past searches. You'll see a row of circular buttons at the top of the Destinations screen. Tapping one will display nearby businesses that you can quickly navigate to.  The Clock button will display your recent searches. The Gas button will show nearby gas stations. This will start Siri, and you can say what you want to search for. If you'd rather type, tap the Keyboard button in the upper-right corner while Siri is active, but this is not recommended while driving. Once you've tapped on a Nearby or Search result, the Maps will calculate a route and display it on the screen. You'll see the estimated time of arrival (ETA), the time the trip will take, and the length. Maps will switch to navigation mode, and you'll hear turn-by-turn directions for your trip. You can close Maps and use other CarPlay apps by tapping the Home button on the screen and your navigation will continue.
