I stumbled up these images from a Google News search. There are some great images of the dash display on this link: http://paultan.org/2012/02/20/new-toyota-prius-c-officially-launched-rm97000-otr/dsc_0014b-4/ Click on image for larger size: Plenty more images: http://paultan.org/2012/02/20/new-t...ly-launched-rm97000-otr/21-prius-c-interiorb/
The "eco drive monitor" in the last picture shows that the screen is capable of displaying a gradient (thus hinting at more than a low amount of colors), but the close-ups clearly only show a few colors as if the screen only supports 256 colors.
what kind of in-dash nav is that. it's not the same as the current one. that looks like it's using garmin navigation technology
