Anyone shine any light on this? Got a CD300 out of a Cavalier, the LCD screen digits work fine, however the screen and buttons dont light up orange like they should either when the sidelights are on or all the time, checked the wiring their is an illumination wire but when i put a live to it i still have no illumination, tried a similar Blaupunkt stereo in the same car, no messing about with wires plug and play onto the ISO and that lights up fine
