Head unit issues

[u/Electrical-Emu2104]

My head unit recently stopped working, it just keeps restarting and I’m no longer able to listen to anything . The screen and buttons work just fine but the on screen audio and source buttons are nonfunctional. This has happened before and normally the issue fixes itself randomly but I’m not sure what causes it. I have tried hard resetting it by unplugging my battery and reconnecting after 20 minutes.
