Scirocco Central

Hello fellow Roc owners,
I've just taken delivery of a 2.0 TSI GT, 2009 and absolutely love it, but there's one tiny niggle I need help with if anybody can point me in the right direction, how do you change the dash display to centigrade????

I cant say for certain, but isnt there an option to chnage the units from metric to imperial, but I am not sure if this affects the speed reading (i.e km/h or mph? I would have to check if the option is on mine, but mine is definately in MPH and celcius.
