My 2016 sonata, lately the radio cuts out. The screen would pop up. Then i can play music for a while. Next thing you know it freezes as if my music is skipping. Then it shuts off. some times it would loop. Like it would load the Hyundai screen again then i would reconnect until the same thing happens again. Or the screen will just be black. At night time the screen is black, but it's illuminated as if it's on. sometimes the radio side can be heard playing on an am station. Does anyone have a solution to this please and thank you. It's been over a few months with no one able to help me.
