My iPhone wil not play music or videos in my Mazda MX5

It sounds like you're experiencing connectivity issues between your iPhone and your Mazda MX5's audio system.

Here are some steps you can try to troubleshoot and resolve the problem:

1. Check Bluetooth Settings:
   1. Ensure that Bluetooth is turned on both on your iPhone and in your car.
   2. On your iPhone, go to Settings > Bluetooth, and make sure it's enabled.
   3. In your car, access the Bluetooth settings and confirm that your iPhone is still recognized and connected.
2. Forget and Reconnect:
   1. On your iPhone, go to Settings > Bluetooth.
   2. Find your Mazda MX5 in the list of paired devices and tap the "i" icon next to it.
   3. Tap "Forget This Device" and confirm the action.
   4. Restart your iPhone.
   5. Reconnect your iPhone to the car's Bluetooth by selecting your car from the list of available devices.
3. Car Audio Source: Ensure that your car audio system is set to the correct source (Bluetooth or AUX) for playing media from your iPhone.
4. Update Software:
   1. Make sure both your iPhone and your car's infotainment system have the latest software updates.
   2. Update your iPhone by going to Settings > General > Software Update.
   3. Check your car's manual or contact the manufacturer for instructions on updating the infotainment system.
5. Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings: Only network settings are removed.
   1. When you reset network settings, previously used networks and VPN settings that weren’t installed by a configuration profile or mobile device management (MDM) are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you’re on. The Wi-Fi and Ask to Join Networks settings remain turned on.
   2. To remove VPN settings installed by a configuration profile, go to Settings > General > Profiles & Device Management, select the configuration profile, then tap Remove Profile. This also removes other settings and accounts provided by the profile. See Install or remove configuration profiles on iPhone in this guide.
   3. To remove network settings installed by MDM, go to Settings > General > Profiles & Device Management, select the management, then tap Remove Management. This also removes other settings and certificates provided by MDM. See “Mobile device management (MDM)” in the iOS Deployment Reference.
   4. Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
   5. 
6. Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings: 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.
