Well, my one year latest map guarantee is up in 5 weeks, and since I just got the 825 maps, I think those are the last maps I'll be getting for a while. This being the case I now consider my manually entered map corrections to have a longer life expectancy, so I bit the bullet and spent 3 hours today "blocking" all of the roads in Staten Island, Brooklyn and Queens, so that I can be routed, and re-route to my heart's content, without having to avoid part of the route every time. Since these changes are not generally applicable for other users, I did not share these changes when entering them, but I would like to share these changes with others who might benefit. I know that maps are keyed to each device, and that Map Share changes are map version-specific. Is it possible for me to copy/share specific files from my map folder (or elsewhere) and have someone else use them to apply the same restrictions to their maps?
