I had downloaded two Garmin maps (both CNNA2011.1), part of a one-time update for two separate nuvis. The Web updater put in two indelible 'Unlocked Regions' which cannot be removed. I have deleted the older 2011.1 in favor of the newer 2011.3 maps, but the unlock codes for the older remains. Now I get two 'Map product not installed' messages, one for each hardware device. I cannot seem to track down where the unlock codes reside. The 'Delete' and 'Properties' buttons are grayed out and inoperative. JetMouse-generated keys are all removable, these are not.
Any ideas?
