Yesterday after a short voyage using Android Auto (Waze and Spotify from Samsung S10e), the sound seemed too in front and centered. Arrived home I figured that the sound was coming exclusively from the dash speaker. Through the sound settings, moving the central sound spot around the cabin (fader and lef/right) it was confirmed that no sound was coming out from the rear speakers or on the front sides. Only when in the central position I could hear the speaker on the top of the dash. Nothing to do else. P...d off. I planned to go to my dealer. This morning, I performed a default reset and everything is back. Anybody has an idea of what's happening?
