Abstract:
1. A system for synchronizing address data for use in a navigation system comprising: a computing device comprising an associated communication subsystem adapted for wireless communications, a user interface permitting entry of address data, and a memory adapted to store the address data; and a vehicle onboard computer system comprising an associated communication subsystem adapted for wireless communications with the computing device and a memory adapted to locally store address data, the vehicle onboard computer system further comprising a navigation system having an associated user interface adapted to allow for selection of an address from the stored address data, the navigation system being adapted to calculate a route based upon the selected address and to display the calculated route on the associated user interface, the vehicle onboard computer system being further adapted to synchronize the locally stored address data with the address data of the computing device using an information synchronization protocol; wherein, changes or additions to the address data in the computing device are synchronized with the locally stored address data of the vehicle onboard computer system, thereby facilitating selection of addresses for route calculation by the navigation system.
