Has anyone used the plug that comes with the owners manual? I hooked it up, and the sound quality is terrible. It sounds like only one channel is comming out. Even if it was mono, on well known songs where I know there is supposed to be lead guitar or vocals on one channel or the other they are barely audible if not at all. The guy at the bike shop says this jack is not stero, and that is as good as it gets, but I don't buy it. I play Ipods and my Iphone on many different systems, and the jack for the honda is a stereo style jack. Any comments?
