No, not really you click from temp to KPH in the DIS 
I have temp and MPH on mine...
Yes, me too...
He said it's a pain to go back from temp to kmph not you cant get mph and temp 
If you mean me, I said it would be a pain to go back from mph to kph when driving abroad. From what I can see, you get the external temp showing whether you have mph or kph displayed.
Out of interest (as I don't get my Mk6 for another 3 weeks) in which section of the DIS is the trip computer displayed. Is it where the mpk/kph is, or the external temp?
