If this is true, is should be added to EURO version to, but I am not sure this is really available? Problem is, if they add it, they need to update and support it. Not sure they are willing to put that time and effort into it.
Don't have it under asian cars as well so how do you know? Is it because there is a map on the maxisys? Those are also available for ferrari, masserati, etc, but the actual software is not developed so it is not on the maxisys itself.
