kinda like a volume switch on many cars were it shows the volume on the screen but there is no white line on the knob to show how much you have turned it from one side to the other

Well - I knew what you were asking - and I told you what it does...
The driver knob rotates freely to the left or right while the digital temp is shown on the A/C display - left cooler/right warmer...
The driver chooses the desired temp - then the passenger uses their dial to choose a warmer of coller temp using the drivers as a base...
So - yes, the driver gets digital readout and establishes the base temp, and the passenger selects a relative warmer/cooler setting using centre-reference calibrated knob.
