I've seen various add-ons for the Prius that seem to be modifying the software that drives the display screen. Has Toyota published the specs of this software, to allow people to modify it, or is this just people reverse-engineering the existing code?
I wouldn't dream of messing with a lot of the computers in the car, but if there's a system that just drives the display screen, it seems like you could mess with that without endangering yourself ...
Thanks! Chris
