I own an 04 WRX with the factory 6 disc cd changer. This morning on my way to work I was listening to one of my cd's when the CD stopped and ejected itself. All the other CD's would not work and ejected when I tried to play them as well. It is cold this morning but it has been colder so I do not think temperature had anything to do with it. The radio still works. Any body have any ideas what the problem is?
