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.

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.
