CarPlay not working on Audi S4

If Apple CarPlay does not start on your S4 when you plug in the USB cable and there is no CarPlay icon in the list of apps in the infotainment system, it can be due to a number of reasons:

  • CarPlay is disabled in the infotainment system settings of your S4.
  • CarPlay is disabled in your iPhone, go to ‘Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps’ and enable both CarPlay and Siri.
  • The Lightning-to-USB cable you’re using is defective. Try a different cable, preferably original Apple cable.
  • The connected USB port on your S4 does not support CarPlay. Try other USB ports.
  • A software glitch is responsible for the CarPlay problem. You can try re-pairing your iPhone after deleting your iPhone in the vehicle and vice versa. You can also try resetting the S4’s infotainment system and/or your iPhone to its factory settings.
  • You’ve an older model of S4 that does not support Apple CarPlay. Only 2017 and later model year Audi S4 vehicles are compatible with CarPlay.

If you still can’t connect CarPlay on your Audi S4, then you should get your vehicle checked by an authorized Audi dealer.

Using Siri on Audi S4

Siri is Apple’s voice recognition feature that helps you to concentrate on the road while driving your S4 as you can control the functions of the iPhone with voice commands.

The virtual assistant allows you to place phone calls, listen to and send text messages, play music on your iPhone, get directions and use other functions of your iPhone hands-free. You can even ask Siri for current weather conditions, stock prices or upcoming events on your calendar.

To access Siri, press and hold the talk button on the steering wheel of your S4 until you hear Siri tone.

Pressing and holding voice command button on the steering wheel starts Siri virtual assistant when CarPlay is active.

You can also access Siri by holding down the home button located at the bottom left corner in the CarPlay app.

Hold home button in Apple CarPlay to start Siri

If the Listen for “Hey Siri” function is enabled in your iPhone device under Siri & Search settings, you can also just simply say: “Hey Siri”. After hearing the audible alert, you can begin asking Siri for assistance.

For best results when using Siri, speak clearly and reduce background noise by closing the windows and moonroof. Also, direct the air vents on dashboard so that they are not pointing towards the vehicle’s microphone.

Which S4 models support CarPlay?

2017 and later model year Audi S4 vehicles are compatible with Apple CarPlay. Wireless Apple CarPlay on S4 is only available on 2021 and later models.

Using Google Maps on Audi S4 with CarPlay

If your iPhone has iOS 14+ operating system, you can freely use Google Maps in Apple CarPlay on your S4. Apple now allows the use of Google Maps in the home screen. Apple has allowed the competitor’s map service in its car application since iOS 12, but the homescreen that was newly introduced in iOS 13 in 2019 could not yet be equipped with maps. Here, users were still limited to Apple’s own map service. With iOS 14 that changes. Now CarPlay automatically selects the last service used for the view.

Using Waze navigation on Audi S4 with CarPlay

You can use Waze navigation app in CarPlay if you have iOS 12 or higher operating system installed on your iPhone. Download and install Waze app from App Store on your iPhone, then start CarPlay on your S4’s infotainment system display. Then touch Waze icon to launch the app.

Using Spotify on S4

You can use Spotify to stream music on your S4. Just install the Spotify app from App Store and its icon will appear in the infotainment display when CarPlay is active.

You can use voice commands to play music hands-free on Spotify with Siri. Just add “on Spotify” at the end so that Siri knows which service you’re referring to (e.g. “Hey, Siri, play my ‘Your Mix of the Week’ playlist on Spotify”).

Siri can play songs, artists, albums, playlists, podcasts, and more. You can also “like” music, ask what’s playing, and control playback (e.g. volume, skip song, play / pause).

Do not disturb while driving

When driving, keep your eyes on the road. A quick look at the navigation device is of course allowed in order not to miss the next junction. The “Do not disturb while driving” function can be activated so that your iPhone does not distract you with unnecessary notifications while driving your S4. iOS 13 extends this option to CarPlay as well. On your iPhone go to Settings > Do Not Disturb, then scroll down and touch “Activate” under “Do not disturb while driving”.

Not all apps are compatible with CarPlay

If you think you can use all your iPhone apps in your Audi S4 with CarPlay, then you’re wrong. The selection of compatible applications is limited, and you have to live with restrictions, especially with messenger apps. iMessage and WhatsApp can be controlled almost exclusively via Siri. That means you cannot see your message history, but only have new messages read out to you or even dictate messages yourself.

The following apps can be used with CarPlay on your S4, among others: Music, Phone, News, Podcasts, Audio books, Audible, Google Maps, Sygic TomTomGO, Whatsapp, calendar, Settings, Telegram, Waze, Spotify, TuneIn, Tidal, Pandora, Youtube Music and Amazon Music.

Sort apps in CarPlay

You can sort CarPlay apps in your S4 quickly and easily through your iPhone. To do this, go to Settings > General > CarPlay, then select your vehicle under “MY CARS”. On the next screen you can rearrange app icons by touching and dragging them. You can also hide icons by touching the minus button on them.
