After latest map updates I plugged in my Nuvi while running BaseCamp
I noted Base Camp showed map 2015.20 on internal memory and 2015.40 on memory card
Went searching my PC for old maps and found the following
A folder "City navigator 2010.20"
another "CNnant 2009
also CSNA8 and CSNA7.
All the individual files in CSNA7 were duplicated in that folder.
How do I get rid of map 2015.20?
Is it OK to remove the duplicate files in CSNA7?
What are to old 2009, 2010.20 folders for?
Seems like a lot of clutter is left after Garmin updates either BaseCamp or the maps on my Nuvi
