I listen to Pandora on my 2017 Mazda 3 linked to the car radio. After service dept. had taken off front bumper to install fog lights when I left I tried again to listen to Pandora. This is what happened: the car info center showed the music being played on Pandora BUT the sound would come through my cell phone. I switched to FM and radio was fine. Clicked back onto Pandora and same thing - radio showed station music being played on Pandora but music would come out of my cell phone rather than the car radio. When I got home I deleted cell phone and reconnected as well as restarting cell phone. Finally works again with music coming from radio rather than cell phone. Any ideas?? Software problem on Mazda? Cell phone problem?
