Please see the attached .pdf for a map of what all the buttons and knobs do on this unit.
If you have any questions, don't hesitate to contact our team.
Many folks ask if this unit has two volume knobs. While it is designed to look like the newer Lexus, it does not have two volume knobs. See the diagram for what the buttons/knobs do. Thanks!
I think there's a typo on the button diagram. The left (driver's side) temp knob displays the climate screen (A/C) in both the Hamilton and OEM systems. The right (passenger) knob displays info in both systems. The diagram indicates that there is no button that displays climate (A/C) for the OEM system, which isn't correct.
Thanks for bringing to my attention! -Dave
