I have Prius 2011 US version. But currently I am in Europe. As I know already it is not possible to change mpg to litres.. But one thing I would like to change - climate control. Now it shows in F, but I would like to see it in Celsius. What if I changed the control unit and placed it from european car. Like this one: http://i1184.photobucket.com/albums/z322/junkyardnut/Climate%20Control%203/5554.jpg Would it show in celsius? Thanks!
It would make sense that a unit from a European vehicle would be in Celsius. You may want to contact seller to verify.
The 2010 and 2011 do not have the ability to convert the Climate Control Unit from F to C. There is a button on the dash to change between mph and kph but no F to C. That is the reason that the OP is asking about changing CC units.
If that is the case I would get an agreement to purchase it with the right to return it if it is not in Celsius.
