In your settings, scroll down to region settings:
If you then click on your region, it will open a in-app window allowing you to select your preferred stations:
You can here see 3 different options:
- Near you (as above; showing you the stations allocated to your localisation)
- Search (as below; to look for a station based on a postcode)
- All Stations (as below; to browse around all the stations available)
Once another region is selected, you will be brought back to your settings and the selected radio will start to play, you can change station anytime you want.
