I am selling a KENWOOD FM transmitter, model CAX-FT20, in red. - Brand: KENWOOD - Model: CAX-FT20 - USB Port: Yes - Bass Boost Function: Yes - Color: Red I purchased this approximately two years ago. After opening it, I never used it, and I haven't had an opportunity to use it since, so I am now selling it.
