How to connect my phone to my Audi's stereo?

I just bought an Audi A4 and I'm having trouble connecting my phone to the car's stereo system. I've tried following the manual but it's not working. Can anyone provide some guidance on how to properly connect my phone?

To connect your phone to your Audi's stereo, start by making sure both devices have Bluetooth turned on. Then, go to the Audi's multimedia or Bluetooth settings and select 'Phone'. Your phone should appear in the list of available devices, select it and follow the prompts to complete the connection. If you're still having trouble, make sure your phone is compatible with your Audi's stereo system.
