I have a 2010 ES350. I think I lost the beep when I press my "Display" button on the steering wheel. Since i have had the car I seem to remember when I pressed the button I wold hear a beep, just like when I press buttons around the Nav display and on the Nav display it's self. I don't remember what I could have pressed.

 

I don't think there is a beep when you press the Display button on the steering wheel.

 

No beep from steering wheel buttons (outside of horn).

 

Thanks all, must have been dreaming.
