i got a free jvc kdr 616 after my jap spec alpine finally died
the reason i mention the jvc is that it has dozens of backlight colour options, it has aux in, and usb.... and its pretty cheap.
i've just set mine to white, but it goes thru the whole spectrum. you can even change the colour of the dial, and screen seperately. it will dim at night if you select the option.
and surprisingly, after i played with its 3 band parametric equalizer long enough, it now sounds pretty damn good.
