City navigator NT europe 10 DVD

I have just downloaded and installed City navigator NT europe 10 on my
oregon 200. Now I have an unlock code for this map/gps unit. Is there a way
to get the DVD in order to have this map available within mapsource ?

Thanks

Sid

I'm missing something. I recently bought the nüvi 855 (replacing a c530). I
already had MapSource from the c530. When I downloaded the 2010 update to the
NA maps for the 855 I had no problem installing it in MapSource as well as in
the 855. Does the NA update differ from the Europe update in some way?
