How do I reset the Audi A4 infotainment system?

I recently purchased an Audi A4 and the infotainment system seems to be frozen. I've tried turning off the car and restarting it, but the issue persists. Is there a way to reset the system?

To reset the infotainment system in your Audi A4, try pressing and holding down the MMI [Menu] button, Volume [+] button, and TONE button together for 10 seconds. This should reset the system and solve any minor issues you may be experiencing.

You can also try disconnecting the car's battery for a few minutes and then reconnecting it. This should reset all the systems in your car, including the infotainment system. However, be aware that doing this may erase your saved radio stations and other preferences.

If the above methods don't work, you may need to schedule a service appointment with your local Audi dealership. The infotainment system may require a software update or there could be a hardware issue that needs to be addressed.
