I mostly want it for streaming music/nav from my phone. I'd want to be able to add my own headphones for better quality. phone functions like call/text.. i'm not a big fan, but sometimes ya gotta do it, and if i could without having to take off my helmet, dig out my phone that'd be nice.
I'd get two so I could use it with a passenger or riding with a friend. I'd like them to have their own music play. I rarely do group rides, but wouldn't mind being connected there
