I have absolutely no sound coming from anywhere. I do not have a headset of any kind. So one question was answered there is an amp, now where is that amp located? I have never owned a touring bike before nor did i recieve any kind of owners/operating manual. When I found the bike it was in a fairly sad shape. I have done alot of work to it to get it back on the road. So I have power to the head unit and my speakers are good, the cb powers up and the PTT button functions. Also on the radio head unit on the bottom there are 2 buttons. One is marked "AMP" the other button is not readable and is also missing. what is this button. The person said the radio and all worked prior to the bike going into storage before my purchase. Thanks so much for the info I have recieved thus far.
