Connect your iPhone to your car's display with Apple CarPlay for maps, calls, and music.
On your iPhone, open Settings, go to General then CarPlay, and make sure Siri is turned on under Settings > Siri & Search. CarPlay requires Siri to function.
Start the car and set its screen to the CarPlay, Apple CarPlay, or wireless-pairing/Bluetooth setup mode. Check the car's manual if you can't find it.
For wired CarPlay, plug the iPhone into the labeled CarPlay USB port with an Apple cable. For wireless, hold the voice-command button on the steering wheel, then pair via Bluetooth/Wi-Fi when the phone prompts you.
When the iPhone shows the CarPlay prompt, tap to allow access while locked. The car display should switch to the CarPlay home screen with your apps.
In Settings > General > CarPlay, tap your car to customize the app layout. Then test Maps, a call, and music to confirm audio routes through the car speakers.
