As I can see even in this link I have last SW, on end of page where are downloading links for updates it writes 2512 Pack 1 and 2512 Pack 2, so that isn't problem as I can see.

I suppose that problem is something else, I was reading everything that I find about this problem on net and I believe that solution is original SD even with old maps, on that SD exist something that we need after we change maps... Or I only think that way, I was reading earlier about GPS on SD cards (for example Renault Tom Tom not live) where is nessesery to save few information a bring them back after map update...
