A friend of mine has a ml 270 with installed navigaton system. However, we're a bit of behind on all the technical stuff, further more, the manual that came with it is on a language we don't understand. So, when we push the Navigaton button, the system request that you insert a DX DISK, of some kind. I am wondering what are those DX DISKS and where i can find them? One more thing, the users manual sais the followind: DaimlerChrysler AG, the radio itself is Blaupunkt. I can't say for sure when the car was manufactured, but i presume, somewhere either: 2001 or 2003...

Also i tried to do a search, but i couldn't find anything that i need, anything specific that is, everyone seems to be looking for CDs, but they don't say what kind, etc.

Another thing, i live in eastern europe, bulgaria; do you know if the maps are developed for that region?

Thanks.
