I have an issue that just started out of the blue on my 06 SG. I'll be riding and lose the volume on the radio. I go to turn it up and it shows front and rear speaker levels. I only have front speakers. I turn off the radio then turn it back on later and everything works fine. I have removed the outer fairing and wiggled the wires around and found nothing. On rare occasions If I turn the bars far left I can cause the problem. I then look for harnesses being pulled tight and once again wiggle the wires nothing.Never comes back on, I'm afraid if I take it to the dealer it will cost a fortune to track down, Anybody every have this happen?
