You can only change speedometer units, as far as I know: miles per hour or kilometers per hour. Assuming you're talking about outside air temperature display, I believe that's fixed, at least it is on third gen Prius.
I would expect all Canadian Prius models to show temperature in Celsius. @Tideland Prius do you know?
Our 3rd gen is celsius, and as far as I know no Fahrenheit option. A real sand pounder: the early fourth gen Prius where you couldn't change the speedo units, mph or kph, and no way to change. Someone was asleep at the wheel, and as far as I know, that was Toyota's solution (go pound sand). @Prodigyplace did you get stung by that?
I have a Prius from 2015. who lives in Canada and drives a Prius C, you can take a picture of a multiplex networked body
