My iPhone won’t connect to any aux cord in any car. I’ve never had problems before with connections to the cords, and my brothers iPhone connected perfectly fine to the aux cord in the car. I recently updated my phone to 16.3.1 and this started happening.
Hi Sopharner04,
Have you tried with any other cables or devices in your car or with your iPhone?
No iPhone that supports iOS 16 has a built-in headphone jack, have you tried with a different adapter as well?
Try isolating the common source of the issue, close your apps, and restart your iPhone as necessary:
Close an app on your iPhone or iPod touch
If you've tested with other devices and adapters and isolated this to your iPhone specifically, contact Apple Support for further help with service options:
Thanks for using the Apple Support Communities.
