The present invention relates to downloaded destinations and an interface for multiple in-vehicle navigation devices. The described method and system for providing navigation assistance to a user of a mobile navigation system includes presenting a web interface to the user, the web interface having one or more user-selectable fields including a destination field. Through the interface, the user can identify a desired destination and download data associated with the destination to a database associated with a call center. Later, the user may download the data to their mobile navigation device, e.g., their vehicle telematics unit, for navigational assistance. In an implementation, such assistance is provided in the form of turn-by-turn directions.
