iphone 15 pro max doesn't work with audi mmi

Have you tried troubleshooting steps to resolve the issue? Sometimes when upgrading to a new phone model, compatibility issues can arise. Here are a few things you can try:

1. Sometimes a simple restart can resolve connectivity issues. Try restarting both your iPhone 15 Pro Max and your Audi MMI system.
2. On your iPhone, go to Settings > Bluetooth, find your Audi MMI in the list of devices, and tap the "i" icon next to it. Then select "Forget This Device." After that, try to re-pair your iPhone with your car's Bluetooth system.
3. Make sure your Audi MMI system is compatible with the iPhone 15 Pro Max. Check for any available updates for the car's firmware that might address compatibility issues with newer phones.
4. If possible, try resetting your Audi MMI system to its factory settings. This might help in establishing a fresh connection with your iPhone.
5. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
6. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
7. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
