I just got my 2010 cube on Wednesday, so excited! I got the 20 color accent lighting and really loved the way the colors faded into each other on my test drive, but now I can't get them to change. When I turn it on it just stays one color until I turn the little knob. I read the instructions and it says hold the button for 3 seconds or something for them to change. If I do this when they're turned off, they just turn on like normal. If I do it when they're already on, they cut off! Is there some weird secret to this I'm not getting?
