the 6 CD Changer in my mazda 6 seems to of disappeared? i can click on the "CD" tab on the deck as much as i want and it will not show, even on the upper part of the red screen it shows that there's nothing there and there is 6 CD's in there. I ejected them all thinking there was a jam or something but apparently not. Even when i cycle through the options on the steering wheel buttons it completely skips the CD.. any help would be awesome!!!
