I found those controls, too, but only with the book in front of me. The base unit does far more than I ever could want, so I'm beyond happy.
The center audio housing is actually easy to remove. If you leave it out you'll have a rather large hole in your dash.I'm the opposite. The one I drove I hated the stack placement. And I actually don't listen to the radio in the car. Are they easy to remove? I'd rather see better over the dash, in the middle.
