VW RCD 510 head unit, fully working, But no code you will need to install and then go to VW or some one with the right software to get the code for it. I’ve had this in my golf for the past 7 years as I originally upgraded from an rcd310 And now have just upgraded to and RCD360 pro. Was working when I removed the head unit, and the disc changer was working fine as well.
