not sure. I bought some sort of conversion kit. I used to commute when I worked and I wanted to listen to work tapes. I never used it, I think I bought a new car and the company was bought out. I was hoping someone whould tell me, I can positively tell you I bought it and its new never used.
im pretty sure that's what it is, u put the cassette tape into your car then use the plug to plug in your phone ipod etc to listen to music off of it threw your car speakers
