Abstract: A method for producing navigation instructions is disclosed. The method includes generating a navigation route. The generated navigation route is translated from textual instructions and/or audio prompts to sign language symbols, and the sign language symbols are provided to a vehicle.

Abstract: A method of determining traffic information for a mobile vehicle includes receiving a plurality of service requests at a call center from a telematics unit via a wireless connection. The service request includes time, date, and vehicle location data. A database of the received service requests is compiled. A plurality of eligible service requests is determined based on the time and date of the received service requests in the database. A traffic profile is determined based on a comparison of digital map data to vehicle location data of the eligible service requests.

Abstract: 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.

Abstract: A method of navigating a vehicle includes determining a route. At least one probable off-route condition is determined based on the route. Digital map information is transmitted based on the determination of the at least one probable off-route condition from a call center to a vehicle telematics unit via a wireless connection.

Abstract: A method for navigation includes providing a route, including at least first and second route portions, at a telematics unit and determining a route status. The method further sends the second route portion to a mobile communication device based on the route status.

Abstract: A method of dynamically selecting a routing service including receiving a route request at a call center from a telematics unit via a wireless connection, determining a vehicle communication configuration responsive to the request, determining map data availability responsive to the request and selecting a routing service option based on the vehicle communication configuration determination and the map data availability determination.

Abstract: The present invention provides a method of operating a telematics enabled mobile vehicle communication system. The method includes receiving a navigation request at a service provider from a telematics unit. The navigation request includes current location information of the telematics unit, destination information, and telematics unit memory capacity information. The method further includes producing navigation instructions based on the received navigation request. The navigation instructions provide directions from the current location of the telematics unit to the destination. The navigation instructions include a plurality of data elements describing the navigation instructions. The amount of data elements included within the navigation instructions is associated with the received telematics unit memory capacity information. The method additionally includes communicating the produced navigation instructions to the telematics unit.

Abstract: The invention provides a method for obtaining an internet connection. The method provides for sending an internet connection request from a call center to a vehicle telematics unit and for providing an IP address and server call in parameters to the vehicle telematics unit. The method also receives an internet connection at the provided IP address with the server call in parameters from the telematics unit at the call center.
