Are you using headphones?
I love my Motorola S9-HD headphones they have all the controls your asking for on them and you can take calls. I've never tried them on a motorcycle though.
You will probobly wear a helmet and I don't think they would fit underneath.
Bummer
As for a stand alone unit if thats what your asking for I havent seen one yet.
Thats not to says that there isn't one if I come accross one I'll post back.
