Thread: City Navigator North America NT 2011.20 USA+CAN (MS with Mexico+IMG+ JCV+3DBuildings+timezone)

I need help please!
I have installed the US CN 2011.20. Firstly it updated my older Mapsource version and in the process locked all my previously unlocked maps! Typical Garmin because the old format (.unl) saved keys cannot be imported into Mapsource 6.16.2 which only imports .ucx files. Anyway I manually unlocked them again one by one but cannot unlock the new USA CN 2011.20 and Mapsouce says the maps is not installed/unauthenticated. I have unlocked the maps for downloading using the Jetmouse keygen but the Mapsource code does not work. I have tried various version of the keygen generator but nothing seems to work. I have used both FID 2265 and 2266 to no avail.

Also the JapanRoadNavi25000 is still locked with the message "unauthenticated" - any idea how I can get around this hurdle - it was unlocked in the older version of Mapsource using the same unlock code.

Any positive suggestions from you folks will be much appreciated. Thanks.
