Hello gang

I need some help for my friend and his newly purchased 2007 TDV8 RRS.

He bought it abroad and promptly figured how to turn the whole car in the appropriate language. However, the Voice Control is still in the original language ! (I am talking about the voice control switch on the left hand side of the steering wheels (at "9 o'clock")

Please let me know if you have a way to switch it or how i can search, as when I try the following, I end up with a zillion threads list.

-voice control options
-voice control language
-voice control switch

-language options
-language switch


Dankeschön
