I just purchased this application and tried some newly opened streets and newly built residences around Cekmekoy, Istanbul area and the application showed them well. The maps are up-to-date and that matters the most with a navigation application. However the application itself is not the one used for Europe or North America version I guess. It doesn't have the reality view for example, but on the other hand the application works fast in current 3D mode. I expect the software will be updated soon, probably after September 30th when the discount price is over. I give five stars for accuracy, speed and to thank Navigon for developing a navigation app only for Turkey, so we don't have to dedicate over 1 GB of space in our phones to keep the map of all Europe. I'd give a sixth star for the price as well, which is the cheapest option among any other alternative.

Its not working properly on my i phone.
