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 invention provides a method of providing route instructions to a mobile vehicle. A communication channel may be established between a client vehicle and a server. The server may be provided the location of the vehicle and it's destination. The server may calculate a route to reach the destination and store the route. One or more maneuver instructions may be downloaded to the vehicle, and the communication channel may then be terminated until the vehicle requires more maneuver instructions. A communication channel may then be reestablished between the vehicle and server and more maneuver instructions may be downloaded to the vehicle.
