CN on SD
My experience with CN was with the Garmin SD card version. So I don't know if the Lifetime maps are different or not. In working with the 2011 version of CN on DVD, I was able to copy CN to my computer and use it there without being connected to the gps.
In a previous response I indicated that I could access CN 2013 on my computer (using CN on SD) in either Basecamp or Mapsource. I just double checked and I can only access CN in Basecamp--not in Mapsource. I have been bouncing back and forth between BC amd MS trying to make to switch to BC. Sorry if I confused anyone with with my reply.
