Most major hotels, embassies, theatres, stations and major landmarks are also shown on the Super Scale Central London map.Searching couldnt be easier, it is the fastest of any mapping application. Our customised predictive keyboard and alphabetical search system finds and displays a street, postcode or point of interest within ten seconds.When connected to GPS, your current position is clearly displayed on the map. Having selected a destination, our A-Z app automatically draws a straight, as the crow flies, blue cotton line from your position to the chosen destination to facilitate route planning. Additionally you can select an alternative start point on the map by pressing down on the map; the app will draw the cotton line from there to your chosen destination. Although the app does not provide a navigation facility with voice guidance, your position is displayed as you move on screen while you drive.The app includes centre GPS, zoom in, zoom out, map switch, day/night mode, route plotting, eraser, info and search buttons on the tool bar.The app includes an on screen simple to understand instruction manual under the information button. We recommend that these instructions are understood and followed to obtain the best use of the unique functions available on this app.Continued use of GPS running in the background can dramatically decrease battery life.
