I know it's hard to see cuz the picture isn't so great, but the rubber reset button is right next to the silver ****.

 

I think you got it. I totally forgot. He had mentioned( the previous owner )that there were bluetooth speakers mounted on the handlebar. It must be a volume control for the speakers because I don't see the silver **** on anybody else's '03 Fatboy.

 

I'll give it a try next time I hit 65 mph
