The audio input choices show a radio, USB, streaming radio, and phone. (I think, don't have the pic in front of me, and will be getting my car next week). Is it possible to connect a non-phone bluetooth audio device? I've got several of those little Tao bluetooth transmit/receive bluetooth device that you can connect to older audio devices - will these work? Has anyone actually done this - any problems or testimonials? I also have an Agptek bluetooth mp3 player - same question - will it connect?
