I have BaseCamp on Windows 7 with maps for City Navigator North America NT
versions 2015.1 and 2015.2 and 2015.3
obviously I only use the most recent version
the old versions take up almost 3 Gig each
I phoned Tech Support and they said to use Control Panel / Uninstall
that frees up the disk space
but it also crashes BaseCamp
can not be fixed
have to Download BaseCamp all over again (and reset all my preferences, etc).
This is insane.
There must be some way to delete old versions of maps without all this hassle !!
