1. A method for providing navigational information to a user, comprising the steps of:
- establishing a real-time connection with the user;
receiving the user'"'"'s location in real time;
generating navigational information for the user using at least one automated processor;
the processor being capable of providing automated navigation information to the user and controlling suspension and re-establishment of the connection with the user;
providing said navigational information to the user;
suspending the connection with the user;
storing trip information regarding the user'"'"'s position and destination at the time the connection was suspended;
re-establishing a real-time connection with the user; and
providing further navigational information to the user, at least partly based on the stored trip information.

Abstract
A system and method for providing navigational information to a user connected in real-time, such as through a wireless telephone, PDA, or other device. The system provides navigational information to the user in the form most useful to the user, such as according to landmarks, or the number of blocks until the next action. The system also provides directions to points of interest along the user'"'"'s route. Further, the system allows the user to suspend and resume a session. Also, the system varies the sampling rate at which the user'"'"'s location is examined, to enhance efficiency and convenience.
