2021 Kona Electric Ultimate trim. The Infotainment System stop outputting all sounds today. Radio, XM, navigation, USB media, Android Auto all have no sound. I pushed the rest button on the display to reboot it several times and turned the vehicle off several times but still no Audio. I checked the fuse and it's okay. Has anyone everywhere this before? Any advice on a fix before I go to dealership? #problem resolved I shut the vehicle off for 30 minutes and came back to it and everything was working again.
Probably not related, but seeing as the 12V battery gets the blame for most ailments related, it might be worth checking the residual voltage is above 12.6 V. Might also be a bad connection in a connector(easy to check at dealer) if the problem persists
I've had this occur twice, the second time on a 1 month old 12V battery.
