Is it possible to change all digital readings in the instrument cluster to metric values on a 2000-01 996?
I know that in the 1998-99 itīs only possible to change the speed and miles to metric values, but the outdoor temperature will not change from Farenheit to Celcius

 

I have an '03 996 and last I checked, it is an option to go all-metric. Just play around with the toggles or read the manual. I had no idea how to do any of that when I got mine. Good luck...
