i use an aftermarket unit which accepts the control, but can't find anyone selling the steering wheel with controller, i'm sure i can ask dealer but that's the last resort cuz it'll cost me a leg and an arm
LOL! I was gonna post the same thing as Heinznfries! I hated the Rav's audio controls on the steering wheel. I put in a different head unit and didn't bother to spend the extra $100 to get and install the part that allowed the steering wheel controls to work with the head unit.
Really the controls aren't worth the effort, they are minimal at best. On the other hand, I kinda like (but still don't use very often) the steering wheel audio controls on our '06 Civic with Nav.
