It seems that there might be a compatibility issue between your iPhone 13 and your 2014 Buick Enclave's Bluetooth system. This could be due to the difference in iOS versions between your old and new iPhone. iOS 17.1.1 might have introduced some changes to the way Bluetooth calls are handled, which might not be compatible with your car's Bluetooth system.
Here are a few things you can try to fix the issue:
- Check your car's Bluetooth system for updates. Some car manufacturers release firmware updates for their infotainment systems that can fix compatibility issues with newer phones. Check your car's owner's manual or contact the manufacturer to see if there are any updates available.
- Update your iPhone to the latest iOS version. Apple releases iOS updates regularly to fix bugs and improve compatibility. Make sure your iPhone is running the latest iOS version to see if that fixes the issue.
- Try resetting your car's Bluetooth system. This will erase all paired devices, so you'll need to re-pair your iPhone to your car afterward.
- Try using a different Bluetooth adapter. If you have a Bluetooth adapter that you can use to connect your iPhone to your car's aux input, try using that instead of Bluetooth. This might bypass the compatibility issue with your car's Bluetooth system.
If none of these solutions work, you may need to contact Apple or Buick for further assistance.
