Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
Are you saying you never get radio to work at all (static at all times) or static only when adjusting volume?
I'm simply asking some follow up questions. I'm a live tech simply trying to help you with your question.
Your earlier replies were unclear to me, hence my request.
I'll opt out at this point, best of luck to you.
