Cd changer will not open

before you press the cd on button keep holding the eject button while you press power on, I know this works for computers etc.

There is a small pin hole on the door of most changers. straiten a paper clip insert in the hole ratchet back and forth on the gear in side to open.

Here is my way of fixing it open the CD doors get a screw driver and some how pry it till it come out other than that youll have to take it apart starting with the cover .

Try holding the power button down for 60 seconds

CD player is not working. Motor will not unload or load discs. It will play CDs fine but cannot change them. Unit will need to be repaired by an audio specialoist or replaced.

Most new car-stereo's don't have an "oldschool" CD-drive, but really a CD-ROM drive; meaning that they won't (properly) read and/or play copy-protected CDs.

Most CD protections are specially designed not to work in CD-ROM drives to prevent copying. As a side-effect most of those protected CDs won't work in car-stereo's.

Try a CD without copy-protection (like an homemade audio CD using burning software on your computer) and see it that works ?

In case that doesn't work either, your car's CD-drive is probably broken ...

cd rack should pull out when you press the button down

Take it to the dealership, your G35 should have a 4 year bumper to bumper on it. They'll replace the radio under warranty most likely.
