1. A method of operating a navigation system for a client device comprising:
- determining an initial position of the client device;
initiating a wireless request for service, the request including transmission of the initial position of the client device;
establishing a voice connection, the voice connection providing transmission of a desired position of the client device; and
wirelessly receiving by the client device, a calculated route from the initial position to the desired position, wherein the calculated route is in a media format capable of being provided in a stepwise sequential fashion in response to commands.

Abstract
A distributed navigation system and method for providing driving instructions to a user. The system includes a service center having a navigation server and associated workstations. The service center stores driving instructions in a continuously updated map database. In response to a user request the instructions are transmitted by way of a wireless network to a client device residing in the user vehicle. The instructions are assembled into sequential stepwise driving directions and stored in a storage device in the client device. Commands from the user trigger playback of the driving instructions in a stepwise fashion.
