Does anyone make a dock with blue tooth that I can connect to my current sound system?

I have a Bose home sound system and I have an apple dock connected to it that allows me to play Pandora. However, it is not blue tooth enabled, so the phone must stay attached to the dock. I've been unable to find a dock that I can connect to the system and allows me to play Pandora while the phone stays with me, just in case I receive a text or call.
