Navigator system will start to become more and more accurate and it will be completly necessary. So Audi tried a new system that took advantage of internet.
The navigation system shows essentially the same imagery that you’d see in a Web browser with Google Earth, but it also shows the car moving through the photographic landscape. Audi overlays road graphics with street names, traffic flow and incident information, and a blue route line when the car has a destination programmed. he car uses its own dedicated data pipe, through T-Mobile, to load the maps. It initially loads maps in a 25-mile radius around itself. When it moves beyond that range it downloads more imagery, but if there is no cell phone signal, it merely shows a blurry background image.
The navigation system maintains a set of locally stored maps, with all the topographic detail and 3D rendered buildings of other Audi models’ navigation, useful for people who don’t care for the satellite look or who don’t want to use a phone’s data plan. Switching between maps is as easy as changing the map view from 2D to perspective. But it would be nice if the navigation system automatically switched back to its locally stored maps when the data connection fails.
Audi uses the same data connection for another set of services: traffic, weather, gas prices, news, and an entry labeled Travel Information. That last category finds a set of landmarks near the car or another location, sorting them by distance. Each entry includes photographs and descriptive text culled from Wikipedia. As these entries are downloaded from the Internet, it can take a little time for the list populate. To prevent distracted driving, the list of landmarks blanks out when the car is moving.
