I have the new 2012 Nav Disc!

[Luv2Camp]

$40 per copy is more than recouping costs! I have the software to burn it as an ISO and was FREE! Discs are cheap. I will give you that it does take a bit if searching on line to get the knowledge on how to do it!

As far as working or not, much of this will depend on the individual reader in the units. MANY of the GM nav units CANNOT handle reading a copied dual layer disk. I made a back up copy of mine about two years ago on high quality discs and many times I would need to eject and reinsert the copy mutliple times for the NAV to recognize it was a map disc. I threw it out.... Glad to hear your works but caution you that it does not mean that it will work for everyone...
