I have a 2004 Touareg that had the factory NAV and cd changer in the rear. I replaced my headunit and they disconnected the factory changer to use the iPod connector. They left the cd magazine in the changer and it now is disconnected and has no power so I can't get the magazine out. Is there a force eject somewhere or can I put a 12 v power supply to the changer's plug temporarily to power it up and eject? Thanks.
