The display items that I can scroll through on my 2009 GS 350 with the DISP button are limited, especially compared to those on my old 1998 LS 400. This is the center screen with the odometer above the steering column. I get outside temperature, Tank Average MPG, Current MPG analog bar, Range Approx, and blank screen. Is there any way to customize this, like adding additional readouts, changing to digital current MPG, deleting the exterior temperature (which is on the center of the dash anyway), add a trip timer, or other functions? I can't find anything about it in the manual.
