I've found that when turning the car off when media is still playing, once you turn the car back on, the music will resume but the duel screen will be collapsed. It happens all the time. And so I turn the radio off before shutting the car down and the duel screen is right there on startup. It did the same thing on my 2020 Hyundai Sonata Limited too!Is there a default setting somewhere that would dual-screen on startup?
Minor annoyance to have to hit the expand arrow every time the engine is on
