It is cyprus-cymps.com v11, I think I picked link in some other thread at this forum, image file named 6324000 and then I used mapset toolkit to install it. I saved earlier all that was originly in the nuvi and now I put it back replacing what I did meantime. It shows that comparing to original content I have some more files, namely: gmapprom.unl, gupdate.gcd, gmapprom.grd, prodkey.bin and prodkeyNA.bin
