I have an 02 Mustang. It has the upgraded 6 Disc changer in it. Recently the changer has been errorin when goin to change cds. it makes clicking noises an seems like somthin is jammed in there. What could the problem be? An does anyone know the specs on it because i am thinkin of just pullin it out an puttin in a Kenwood KDC-MP425 that i have layin around.
