I have a 2020 Ascent Limited (Canadian Model), the mileage is only 2500 KM (1,560 Miles) and the radio (Harmon Kardon package) suddenly stopped "making sound" . I can change stations and sources. I can see my Aux and Bluetooth libraries, as well as I can see my Apple and Spotify libraries when using Apple CarPlay. As it stands, I can only hear the Nav system from the speakers. Even the phone audio has stopped broadcasting (making sound), but the dialling and other controls still function.... Any thoughts? Is there something I am missing, or should I run to a dealer????
