Hey Uncle_Toby

1. Check the cable and connections: Make sure that the cable you're using is compatible with your iPhone 15 Pro Max and that it's properly connected to both your phone and your car stereo. Ensure that there are no damages to the cable or connectors.
2. Enable USB Accessories in Settings: In some cases, your iPhone may not recognize the accessory connected via USB-C. You can try enabling USB Accessories under Settings to see if it resolves the issue. Here's how:

• • Go to Settings on your iPhone.
  • Scroll down and select Face ID & Passcode or Touch ID & Passcode.
  • Enter your passcode if prompted.
  • Scroll down to the section titled "Allow Access When Locked."
  • Toggle the switch next to "USB Accessories" to the ON position.

1. Check car stereo settings: Ensure that your car stereo is set to the correct input source for playing music from an external device. Sometimes, car stereos have multiple input options (e.g., AUX, Bluetooth, USB), so make sure the correct input is selected.
2. Restart your iPhone and car stereo: Try restarting both your iPhone and your car stereo to see if it resolves any temporary glitches.
3. Update software: Ensure that your iPhone's software is up to date by going to Settings > General > Software Update. If there's an available update, install it and then try connecting again.
4. Reset network settings: Sometimes, resetting your iPhone's network settings can help resolve connectivity issues. Go to Settings > General > Reset > Reset Network Settings. Note that this will reset Wi-Fi, Bluetooth, and VPN settings, so you'll need to re-enter Wi-Fi passwords and re-pair Bluetooth devices.
5. Contact support: If none of the above solutions work, it's possible that there may be an issue with either your iPhone or your car stereo. In this case, contacting Apple Support or the manufacturer of your car stereo for further assistance may be necessary.
