How can I adjust the audio settings on my Audi A4?

I recently purchased an Audi A4 and I am having trouble adjusting the audio settings. The manual is not very clear, can someone provide some tips or steps on how to adjust the audio settings on my car?

To adjust the audio settings on your Audi A4, simply press the MEDIA button on your control panel and use the arrow keys to navigate to the audio settings. From there, you can adjust the bass, treble, balance, and other audio settings to your liking.

I found it helpful to go into the settings menu on the main display and access the audio settings from there. From there, you can also adjust the volume levels for each audio source such as radio, Bluetooth, and auxiliary.
