After Installation of the new Firmware 5.60 on a Garmin Montana 600 it was not possible to view the City Navigator map CNEUNT 2014.40 on it. All existent unlockers are not able to fix this. The unlocked images from this Forum are also not visible / authenficated. After downgrading the device to 5.40 Firmware the map could be used on the device again.
It seems so, that all new Garmin Firmware updates for all devices will include this special copy protection!
