It is not from this site. I had downloaded it some time ago and can't recall where..
The file is an unlocked Garmin Canada Topo v.4 of BC
I tried using mapsettoolkit and cGPS mapper to upload it onto Basecamp.. It seems to successfully convert the file, but then I am unable to open Mapsource or Basecamp afterwards, unless I uninstall the the mapset.
I simply get a message stating that there is a problem with the map installation and I must reinstall and open basemap again..
