I listen to music on my Voyager quite often. It has a, auto volume adjust though, so it turns itself down as your speed decreases.
I turn it off in parking lots and residential areas.
I'm going to see if I can pipe my GPS through the speakers while I listen to Spotify and have the helmet set up for the intercom.
Sometimes I like the solitude of me an the engine. Sometimes I like some music; especially eating up the miles on boring highways.
I DO like having the stereo on the Voyager; I'm still undecided about the Rocket though.
