Lets see if someone can give me an answer about which file do I need to my Nüvi 50LM.

Garmin City Navigator Europe NTU (Unicode) 2013.30 or City Navigator Europe NT 2013.30

Last time it work with City Navigator Europe NT 2013.21.

I really would once and for all to know which files work on my Nüvi 50LM.
So many options, mapsource locked, unlocked, unicode, files that end with 2013:21....

best
