My son has a 1999 trailblazer with the radio controls on the sides of the steer wheel. I need to remove the steering wheel but I haven't been successful in finding any info on how to remove it. There are the 2 t screws in the back to remove the back cover. But we need to know how to remove the horn cover. And yes the air bags have been disconnected properly. There are no holes in the back of the cover and I can't find anything on it to pop it off. Any information would be greatly appreciated.

We need to remove the black center piece.
