The headunit has begun to restart randomly and the speakers have also stopped working. Only when resetting the battery will the speakers power back on. Is this an electrical/grounding issue from the headunit or something else? Also by chance, my steering has begun to feel verrryy heavy. I'm not sure if the issues are related, or if the truck is just falling apart at once. I intend to flush the power steering fluid today and look at the intermediate shaft. Merry Christmas to me!

Thanks!
