RNS850 - activate language Polish

[pepeEL]

Hi all users :)
I have a problem. I update firmware in my RNS850 to version K0821. This firmware should include POLISH language menu and maps. But after update in settings language i dont see option to select POLISH.
When i go to green menu i see in config that polish is available but i can not set it. Now select in Green Menu is en_GB

Probably by VCDS Polish lang should be activate. But is anybody who can tell me where in VCDS in which module ? And in Adaptation or Codding ? Please help me...
