The Mail.ru property is the best maps on the mobile. Maps can be uploaded and used offline. Made simple, clear and easy. Probably the key word is easy, because these maps take an amazingly small place. Lungs do not mean empty, the maps are very detailed. I also used it on foot, in Turkey, in St. Petersburg. Of course, the program has a navigator, very convenient, you will not have to get used to it. With voice and the necessary information on the screen.
