The Pioneer X-HM50 is a compact mini component system with a USB port and CD player. Made in 2012. I used it for a few years, but it has been stored in a box in a closet for over 8 years. CD, USB, and radio operation have been confirmed. iPod and iPhone compatibility have not been confirmed. The CD tray sometimes retracts immediately after opening. There is no instruction manual, so I operated it while looking at the online manual. I don't know much about mini component systems, so please understand that I cannot answer detailed questions. It was stored after use, so it still has dust and dirt. It's about 13 years old, so I would like those who understand the condition to purchase it. When shipping, I will only wrap this box in plastic, so please understand. Please check the images carefully before considering purchasing.
