Hello , I have a 2006 prius and I am trying to change Region to European ( MPG <=> l/100km , temperature in C ) , is it possible ? I tried Setting model info , but looks like its not saving , everytime I open this menu it always shows US , no matter what I set there , To get to this setup menu : 1. double press power button ( without brake pedal ) 2. when screen switches on press Display button 3. tap on screens ( top-left corner , bottom-left corner ) x3 ( 3 times ) you should be able to see now first "hidden menu" 4. on that menu press "Menu" on the screen ( top right corner ) 5. on menu press top-left corner of the screen then bottom-right corner of the screen now you should able to see another menu with "Model Info" button , when you tap on this you are able to select between "US , EU LH , EU RH , CAN , AUSTRALIA , Mid.E ... " so I am trying to select any other option than US and then pressing to "Set" , if I go back to menu and open this setup again it has latest changes but when I try to power on the car , or restart this "mode" it always shows US there , so is it possible to change "region" like this ? if not , is there any other way ?
