How to troubleshoot a malfunctioning radio in Audi A4?

I recently noticed that my Audi A4's radio is not functioning properly. It keeps turning off by itself and the audio quality is poor. What could be the issue and how can I fix it?

First, check the fuse box and make sure the fuse for the radio is not blown. If it is, replace it with a new one. You can also try resetting the radio by disconnecting the car battery for a few minutes.

If the fuse and reset do not solve the issue, it could be a problem with the wiring. Take your Audi to a trusted mechanic or dealership to have the wiring checked.
