So I started my car this morning and there was no sound coming out of the radio. The MMI system works fine and it lets me switch stations but there is no sound. I switched to my Sirius radio and that worked fine. I then plugged in my phone and the music on that worked as well. I have tried resetting the MMI a couple times but the problem still persists. Is there anything that I can try before bringing it into a service center?
