Wanted to see how many people out there have an actual button for their rear window shade? The manual shows the button to be amongst the many on the overhead console, however in my car it's just a blank spot. Isn't that odd? The only way to otherwise access the shade without having to go through COMAND is to program the "favorite" button as the shade, but it strikes me as bizzare that I don't have a dedicated button! Anyone else???
