The listing, Motorola Rokr T505 Speakerphone Headset has ended.
This works with the radio in your car and your bluetooth telephone. You tune your radio to a certain frequency and have bluetooth on and you can talk handsfree. I used it a great deal in my other Honda, but my new Honda has handsfree link. I don't need it anymore, thought someone else could use it as much as I did. Works well, has a few scratches on it, nothing major. I have printed off the manual and will enclose it to whomever gets it from me. Happy Bidding!!!
