The present invention provides a method of operating a telematics enabled mobile vehicle communication system. The method includes receiving a navigation request from a user interface to a telematics unit, receiving a location signal defining an approximate geographic location of the telematics unit to the telematics unit, analyzing the navigation request and the location signal to produce a navigation route defined by a plurality of navigation points including an initial navigation point and one or more additional navigation points, producing a local navigation zone and a global navigation zone based on the analyzed location signal wherein each navigation zone defines a geographic area concentrically radiating from a known geographic location, determining which navigation zone the initial navigation point is within, and producing navigation instructions that provide direction to navigation points along the navigation route and are based on the determined navigation zone and the navigation route. |
