OK, I have tried to make those copies of the NAV disks (east and west) but even though the software says the copy is complete, the disks never work. I swear I have toasted 20 or more disks this way to no avail. I have a close friend who needs a set but of course I do not want to give him mine. Is there any way someone can make a copy of them, and send them to me, for a slight charge? Please? Thanks!
