Quick question: I cannot find this in any of the manuals that came with the car. Is there a way to configure what is displayed in the center dash. The three "preset" options are speed, "trip 1," and the last 20 minute MPG graph. Questions: (1) Is there a way to "black it out" so that it shows only the items at the corners (time, temp, odometer and miles to empty)?; (2) if not, are the three options configurable in any manner?
