Claim:
A method for transferring information from a portable agenda replication device to a vehicle navigation system, the method including: accepting entry of an agenda comprising a destination and a requested time of arrival at the destination; storing the agenda in a computer readable storage mechanism; retrieving the agenda from the storage mechanism; transmitting the retrieved agenda to the vehicle navigation system, and instructing the vehicle navigation system to use the agenda to determine a route to follow to the destination based upon the requested time of arrival, and also based upon at least one of: (a) a cellphone coverage preference, (b) a road condition preference, or (c) a scenic route preference; and using the portable agenda replication device to update the agenda in the middle of a multiple-stop trip by determining whether a travel agenda table stored in the vehicle navigation system matches that stored in the portable agenda replication device and, in the event there is not a match, updating a calendar item in the vehicle navigation system with agenda information from a calendar item in the portable agenda replication device and, once a determination is made that the agenda information in the vehicle navigation system matches the information stored in the portable agenda replication device, selecting all items in the travel agenda table stored in the vehicle navigation system that do not have a calculated route associated therewith; wherein, when a location is dropped from the agenda or a new entry is added to the agenda, the route is automatically recalculated by the vehicle navigation system in response to the vehicle navigation system receiving the updated agenda from the portable agenda replication device.
