Navigation zoom level.

[tszukow]

Hi all, for last few weeks I noticed that I can not zoom the map to the maximum level as use to be able, instead I getting message "Building scale is not available in this area" I did not update navigation or change any settings.I called Nissan customer service if the Carwings updates has something to do with it-the say Carwings does not interfere with the navigation and suggested to see the dealer.
I can zoom the map to the third dash on the scale maximum. any idea?
