I still have never gotten that tray out, cursed thing.
As far as the changer goes from what it looks like the light for the active disk glows green. I don't know if the td-45z has dimmer controls, my cd-40z doesn't although it is considerably less obnoxious at night than my previous HU (JVC). Are you planning on doing the install yourself? You might want to see if there is a shop near you that has Nak on display so u can see if it really tickles your fancy. I am sure if you went with the nak you would be much happier with the sound
