This thing is badass if you haven't seen it. Plugs into the back of your late model ford stereo (Mach stereo) and acts as an additional CD player but is a MP3 player. It has SSA voice speach of tracks and songs. Has a cradel to upload and download songs from so it's easy to transport. Someting to put on your xmas wish list.
