IF you did hook up the illumination, there might be something you have to do with your headunit's settings. The Alpine I have currently has a setting for "auto dim" or something like that. Once that is selected, the unit will dim when you turn on the lights.edsmith42 said:Hmmm... The odd things is that I actually DID hook the illumination wire from the head unit to the illumination wire in the WRX harness.... grumble grumble... probably some weird JVC incompatibility

I've only used Pioneer and Alpine head units, so maybe others work better, but I'd like to see an aftermarket unit that has full-range dimming to match the rest of the instrument dimming. Not just one level with lights off, and a lower level with lights on. It should be tied to the dash dimming control, just like the factory radio.
