The knobs at the bottom from left to right control volume, temperature, and fan speed. AC can be controlled thru the knobs or thru the touch screen. the knobs and buttons are RGB backlit and can be customized. Left "power" button mutes audio and right power button turns on/off climate.

Steering wheel controls work out of the box!

Let me know if you have any other questions!
