Thanks a lot for that information, fluorescent! I thought I had the latest FW version in my nüvi 205, but I was wrong. I just updated it through WebUpdater. It went from v2.7 to v7.1:

swversion

Result is my nüvi 205 now recognizes CN Europe NT 2011.40!
Thanks again and rep+ for you!

Apparently there is no FW update for my nüvi 350. It already holds the recent most FW (v6.2). Waiting in line for the MapSource version then...
