Is the CB already Bluetooth? If it is my Sena SMH10 Bluetooth headset should just work with that without adding the other Sena piece. If I want to add the bikes radio playing through the Sena I will need to add the other Sena Bluetooth hub. Even if I add the other Sena piece to get the Bluetooth hub I don't think that will need to be mounted on the dash. I think it will work in the cuby or saddlebag.
