It sounds like your iPhone is prioritizing your hearing aids over your car's Bluetooth system for call audio. To address this, you can adjust the Call Audio Routing settings on your iPhone. Here's how:
1. Check Call Audio Routing Settings:
- Go to Settings ➡️ Accessibility ➡️ Touch ➡️ Call Audio Routing.
- Set it to Bluetooth Headset or Automatic. This ensures the audio routes to your car's Bluetooth when connected.
2. Prioritize Your Car's Bluetooth:
- Disconnect your hearing aids temporarily and pair your car's Bluetooth system first. Then reconnect your hearing aids. This may help your iPhone prioritize the car's system for calls.
3. Adjust Hearing Device Settings:
- Go to Settings ➡️ Accessibility ➡️ Hearing Devices.
- Check if there's an option to disable call audio streaming to your hearing aids while keeping them connected for other functions.
