Marantz audio remote control RC6001CM. I used to use it with CD and MD decks, but I no longer need it as I got rid of them. It was working fine the last time I used it, but please understand that I cannot confirm if it still works, so please purchase it with that in mind. There are scratches and dirt from use. The battery cover on the back is missing. Please check the product condition in the images. The actual color may differ slightly depending on your computer or smartphone.
