Once you registered and make your own radio playlist in radiotrucker.com , got "My lists" menu,click on your list and select "Export to game" and pick your game, it will send you a zip file containing another file called live_streams.sii , place this in your <documents folder>\Euro Truck Simulator 2 folder (and overwrite existing) , in the game, pressing R will take you to radio widget or from menu in main screen in the game, there is a radio button. You can select your keys from game settings.
