I was looking at bluetooth hu's. Found this.
I noticed that there is a bluetooth adapter for this hu. Can I do the same thing to a hu that has a usb connection? My new cell phone won't work on my current hu unless I have the bluetooth adapter ... ... from what I read online. I also treid connecting it bvia usb and selecting all the options that are given from the usb connecting. NONE of them worked, all I can do via usb connection is charge my cell phone. It's a Nokia E73 Mode.
