Is there a way to ad the Bose Steering Wheel mounted volume/cd control if u don't already have it. I have found that there is a blank face where it should go thats why i ask. My wife's got it in her Acura CL 3.0, I'm always reaching for it in my car after driving in hers. If it's available where do we get it & how easy is it to install. By the way, I already have the Bose, just no remote.
