2004-2005 Bluetooth Coastal grey-out fix

Can anyone suggest a website where I can attempt to sell a Coastal Tech device that I purchased for my 2004 (also works on 2005). This product allows the Prius driver or passenger to disallow the "gray out" so that the blue tooth key pad can be used by driver or passenger while the vehicle is in motion. The product was removed from my 2004 when I purchased a 2009 recently. The product does not work on the 2009.

I attempted to post the information in Prius chat, but Prius Chat seems to disallow such postings

 

The unit is easy to install...my dealer did it for me for free while doing other maintenance. If you are interested I will contact the manufacturer to get the original installations instructions via email, and forward them.

The method of use is as follows:
bring up the telephone screen by pressing the telephone key on the steering wheel. The numbered dialing pad will not be grayed out. In about 45 to 60 seconds it will gray out. If you still need it to be operative...simply again press the steering wheel key for the phone screen.

I paid about $165.00 for the device including shipping.
I am selling it for $107.00 including postal shipping with a tracking number. I can accept either a Visa number or a check.
