Is there a way to get an instantaneous and continuous numeric display of the current gas mileage? Not history or trip average! Just right now all the time.

 

I believe that is the default on Driver 1 screen but not numeric - it's a line graph of some sort. I never use it though.

 

From a black center screen, when I push down once it shows me current mileage (the line bar described above) and the average since reset, which I reset after fill up. I don't think it does a numerical instantaneous mileage display.
