So my car’s music system has been working perfect until today, all of the sudden I can’t change the music with the car, I can only use my phone. But the circle dial that controls the system is working for everything else but changing the music. It’s a minuscule issue but causing a real inconvenience. It’s making it use my phone more while driving. Any suggestions how I can reset the system? I tried changing the usb cord but still no change. Any advice??
