How to set radio stations in Audi A1?

I can't figure out how to set my favourite radio stations in my Audi A1. I have tried following the manual but it doesn't seem to be working. Can anyone help me with the steps?

To set your favourite radio stations in your Audi A1, first turn on the car's radio and tune in to the desired station. Then, press and hold the corresponding preset button until the station name is displayed. Repeat this process for each station you want to save.

You can also save stations using the MMI system in your Audi A1. Just navigate to the radio menu, select 'Preset stations' and then choose 'Add station'. Enter the desired frequency and press 'OK'. Your station is now saved.
