open console and type for example "bind j +vehicles_radio_gui" and now if you press j or the key you want it to be you can choose it. to choose the station you need to move your mose to that station you want it to be! and now you want to press the button you binded it to. No problem guys, i found that out 1 years ago. Now, if you don't mind. i'll have to go. Have a good game with the mod!
