WhatsApp on CarPlay

Hey Shadow3821,

Next, we'd confirm that WhatsApp is enabled for cellular data in Settings > Cellular and that Cellular Data is enabled here at the top, as well.

If it continues, CarPlay works with the Messages app and other apps without any issues, then you'd want to contact WhatsApp again for their next steps. The fact that you can use these other apps without a problem makes it clear this issue would be best supported by WhatsApp Support: https://support.apple.com/HT207959 or contact WhatsApp Support here: https://www.whatsapp.com/contact/

Since they've developed the app, they'll know how to take it from here.

Wishing you well, take care.

Hi there Shadow3821,

Welcome to Apple Support Communities. First, make sure that you are using the most current iOS version:

If you need help with CarPlay

Be sure to test the issue after each step, and let us know the outcome.

We look forward to hearing back from you. 

Thanks for the reply back, Shadow3821.

Since you've tested it in several vehicles, let further narrow down what's going on. Is CarPlay able to read incoming messages sent through iMessage on your device? We want to see if the WhatsApp app is the only one with issues being used through CarPlay.

Also, have you checked for WhatsApp updates in the App Store? You may have some app updates if you've updated your iOS recently.

Lastly, we'd recommend removing the WhatsApp app, then reinstalling it.

Keep us updated with how these steps go.

Best regards.
