The audio button when pushed does nothing. It does turn the volume up and down like it is supposed to. What buttons on the radio (if any) can i make audio control changes with? The operator manual says the soft buttons (4-6) can do this but they are doing nothing on my radio. Can someone steer me in the right direction on this? It is a 2011 ultra. I'm trying to decide what has the problem, radio or handlebar controls. The handlebar audio control used to work.
