iPhone connecting to Hyundai Kona bluetooth

Hi CeliaAC,

Welcome to Apple Support Communities! Let's look into this together and go over all options to have your iPhone sync with your vehicle as expected. We'll look into all options, and if we isolate the issue to your car's stereo directly, we may refer to their support for further assistance.

To start, please let us know a bit more about what's going on. Are you seeing any kind of error message when attempting to access contacts in your vehicle? Does your car stereo support CarPlay via Bluetooth?

Is your iPhone fully updated? If not, follow the steps in this guide to back up your data and update:

Update your iPhone, iPad, or iPod touch

Similarly, have you had an opportunity to verify that the firmware of your car stereo is fully up-to-date? It may be necessary to consult your car stereo's user guide for instructions.

If the issue persists, head into Settings > Bluetooth on iPhone. Do you see your vehicle listed here? If so, tap on the blue "i" to view details, and then ensure that the option to "Sync Contacts" is enabled. Next, choose to forget your vehicle here, in order to pair it again with your iPhone. Test to see if your contacts sync at that point.

We're here for you if you've got any questions.

Have a great day!
