Sorry - should have stated that I'm attempting to update a recently purchased AVIC-8100nex.

Thanks for sharing this. I've downloaded and copied to my USB drive. The Naviextras Toolbox utility appears to recognize the update as being for 2015Q3, which is cool, and leads me to believe that it is copied to the drive correctly. However, when I use the SyncTool utility in the car to update the maps, I get an error: "Update package is invalid". Any ideas what I might have done wrong? Thanks, tackytony
