The beep everytime I change the volume or channel from the steering wheel controls is just plain annoying! Can I stop it from doing that?
We know more about your CX-9 than your dealer does.
Yes you can...
In section 6-28 and section 6-29 of the owner's manual they tell you how to do this. You'll need to use the audio control dial to turn the beep off. Press the center of the dial to cycle through the different functions. Once you get to the one that says "BEEP ON", turn the dial to the left until it says "BEEP OFF".
Good Luck!
