If there is an online radio stream that you would like to listen to but is not currently available through TuneIn, you can save the internet stream as a Custom Station through the BluOS app.
To do this, open the navigation drawer and select TuneIn > Favorites > Add Custom Station. In the pop-up window that appears, enter the name you would like this station to appear as and the Internet address or URL of the stream and select OK. Your named Custom Station will now appear as a TuneIn Favorite for easy access.
