Here Drive's functionality is really inconsistent across OSes. I'm from Trinidad and Tobago, W.I. Once nokia abandoned symbian and upgraded from 7.5 devices, Here Drive, has been issuing an error basically sayng they cannot route destinations within my region due to lack of updated maps. Surprisingly, I used an andriod phone, accessed Here Maps, and found that I could navigate to destinations within my country using this android counterpart. WP here drive still does not function. This goes to show how awful support has been. smh
