<p>Method, apparatus, and programs for synchronizing navigation data. Data synchronization is established between a receiver and a navigation device based on matching of a header of navigation data. The receiver receives the navigation data from the navigation device. If, subsequently, the data synchronization is interrupted, information related to the data synchronization from the receiver is retrieved. The data synchronization is then re-established between the receiver and the navigation device based on the retrieved information.</p> |
