I found this while cleaning out my wife's parents' house. I can't confirm if it works, so I'm selling it as junk. Please be aware of this. (It's made in Japan, so it's probably likely to work?) I think it's a CD changer for a car. It's a product from about 30 years ago, and I can't find any other listings for it, so it might be quite rare? I'm not sure how to price it, so I'm open to negotiation. If you're interested, please leave a comment.
