I just got a used 05 and I'm having aproblem with the dealer. My radio works fine but does not light up at night. it shows the stations but thats it nun of the buttons light up. They are telling me they dont think it should. I just go rid of my 05 Trailblazer and that lit up I find it hard to belive you cant see any buttons in the dark. I do have controls on the wheel but I think the radio it shelf should lite up. By the way its a single CD
