    Abstract: The described method and system provide for GPS navigation utilizing a previously stored position as a starting port when current position information is not available. The method may be implemented at a GPS-capable device (e.g. a telematics unit in one implementation) or through a call center that provides navigation services to a telecommunications device (e.g. a telematics unit in another implementation). A user input corresponding to an intended destination is received, it is determined whether current position information of the user is available; and, if not available, a route to the intended destination is calculated based on a previously stored position of the user. It may further be determined whether current position information of the user subsequently becomes available, and, when available, it may further be determined whether the user is on the calculated route that was based on the previously stored position of the user.
