I've had lots of cars in the last few decades and my CRV is the only one with it in that location.You press the black push button on the right side of the dash just like every car in the last few decades
Some people miss that the button is even there because it's hidden behind the steering wheel
You can also use it to dim or brighten the display at night by rotating the knob but you have to be in a totally dark environment. On the 5th Gen if you try it even at dusk rotating the knob will not do anything.Oh dear. Found it. It was hiding behind the steering wheel.
