Has anyone ever found coding to allow the radio to remain on after the door is opened when the ignition is off? I found some that allows the windows to be rolled up after the door opens and ignition off. I used to have a Mini and the radio would stay on for a certain time period after the door was opened or it would turn off when I locked my car. Looking for the same in my 2017 Audi TTS. Any help would be appreciated. Thanks
