Is there anyway of saving on internet data charges by downloading a subset of the full North American maps rather than the full 5GB suite? In my case, I would like to download Canada only (which would be a lot smaller and is all I need). I seem to recall one could some time ago specify a map region eg. Canada + northern states, but that option does not seem to be available now, at least with my Nuvi 2597LMT.
Any help appreciated......
