Posted in Audio, but no response so thought I would try here. My in trunk cd changer broke when the magazine would not eject. First I got an error message about the magazine, but now I am getting a "no cd detected" message. I replaced the changer, but still get no cd detected. The head unit works otherwise. Now I suspect a wiring problem. Do I have to pull the head unit to check the wiring harness? Even though it is not too cool, I like the stock unit, but just want it to work. Any ideas. Thanks.
