I was told by a regular who recently parted with his 300C that there was some doubt as to whether all copies would work on the mapping device player. However if they did and were read once then they updated the device and you could NOT revert back to an earlier edition of the map/disc. Also that there was a story to the effect that that particular device while able to read copied discs found them somewhat indigestible and the reader could incur damage and end up not playing at all. Perhaps some of our members who are more into DVD/computers/copying software etc would comment.
