Hi, I have transferred CN Europe NT 2011.20 to my Dakota 20 - no probs. Transferred 3D buildings - shows up on device when selecting maps as CN Europe NT 2011.20 3D Italy/turkey (unlocked) and when using to navigate it doesn't appear any different to normal city navigator. Also loaded JCV, again no sign when navigating. Do 3D and JCV work with the Dakota or is 3D set for Italy/ Turkey? (Or is it something else?)
