2018 Touring L having bluetooth phone, (Oneplus 9 Pro android 12) disconnect issues and wanted to do soft reset. Car loses contact with phone, disappears in the car's phone registery, but remains on the phone. Tried the procedure holding the volume and tune buttons down. Screen goes immediately black, doesn't do anything. Held for a minute, same thing. Radio just comes back on when I push the Power/Volume button.Tried touch and hold upper left and right corners of screen while radio on, nothing. Have not tried the "Hard reset" using left temp buttons as I was avoiding having to reprogram everything. Car has had all programming updates. Is there another procedure I'm missing?
