Navi in E83 Help

Hi. Im a newb and need help about upgrading my navigation.
I found the topic for maps 2016 Europe. Is there any way to get ex-Yugo maps? Like Serbia, Bosnia, ...? Because, only Croatia and Slovenia are avaliable in DVD2.

I have an E83 X3 and also the version it says is SW 4-1/00. I cant find other information.

THANKS for your help guys
