When we go camping in our VW Passat, 2018 wagon, we settle in for the night in the back, and sometimes listen to a film score. If the ignition is left on, outside lights stay on, so I turn the ignition off to ensure the battery doesn't drain as much. The sound stays on – but only for about 30 minutes. Then the sound turns off. So I have to grope around in the dark, turn the console thing back on, try to find the point where the sound stopped (maybe it picks up at the same point automatically, but I'm not sure about that), and away we go for another 30 minutes.

Is there a way to make the sound stay on longer? I can't find any settings in any of the menus.
