a yes i just bought a alpine 9886, new one and i thought the 9886 had color schemes to choose from? like 4 different ones? where is the button to change this, i looked all through the head unit, tryed every button, in know its supose to be in the display setup, i have all the dimmer setups but no illumination? is there a wire in the back you have to hook up to make it work and show up? what whould you hook it up to? thanks
