Boy, what a humbling discovery. I was out in the garage fiddling on the weekend (meant to post this earlier) and just for kicks I had the stereo playing as I worked. As I was wiping the fairing controls and switches I hit the audio mode button inadvertently. As I cycled through it, imagine my surprise when I found the "ambiance" controller. What a doofus! Now I have the sound I was missing out on due to my dumbhead mistake. No idea how I totally missed this.
