As always, Stu is right on the money. Garmin will discontinue BlueCharts after the most recent 2010 version. I initially had an ugly dispute with the folks at Garmin about the transferability of a BlueCharts disc I bought but could not access. They claimed BlueCharts is not transferable unless you sell it with the device onto which the maps are loaded. However, a reading of the license agreement shows that Garmin actually meant purchasers to be able to transfer the discs or cards, provided they first erased the maps from their own units. In other words, you're not supposed to sell your cake and eat it too. I finally ended up with a wonderfully sweet woman at Garmin who not only sent me a new 2008 west coast disc, but said I could upgrade to 2010 when I got my 76. Waiting for the update now.
