This unit does not have a power harness included. I used a bench power supply to confirm that it powers up briefly. Attempting to interact with the buttons caused it to power on, cycle through what sounded like the unit trying to find/play a CD, then power back down. It's possible that more cables need to be plugged in for it to work as intended, but it's also possible it's in need of repair, and I'm unable to determine which is true. Includes unit only; no accessories are included.
