no 3D maps in basecamp (zumo590 owner)

Hello,
I bought zumo590 LM including maps for europe. I have downlodated the maps with Garmin Express to my mac (tried PC too) but those ones, look flat. When I switch to the device's map I can see 3 terrainn which is very useful for me to plan a ride through hils, etc..
In map manager they seem to be the same (city navigator europe ntu 2017.1) the downloaded one and maps installed on device.
I don't get it - why I cannot see 3D maps without attached devices?
(i have made a tweak with disk image to simulate connected device, but why do we have to do such workarounds if the maps seem to be installed)
