RMC Change region US to EU

[multfilm]

Hello! Help change the region RMC Audi A6 C7 2013. I have a car from America. When updating Audi_RMC_K16158 writes "A region conflict occurred!". On the green menu not "Ignore region" and section SWDL or System > Internal. Now there is a firmware RMC_NAR_P11474.
Thanks.
