How can I switch radio stations in my Audi A7 without taking my hands off the steering wheel?

I recently got an Audi A7 and I am still getting used to all the features. I want to know if there is a way to switch radio stations while driving, without taking my hands off the steering wheel. It would make things much more convenient and safe.

To switch radio stations without taking your hands off the steering wheel, you can use the voice control feature. Simply say 'change radio station to (station name)' and it will switch automatically.
