NAVIGATION BLIND STARTUP
First Claim
1. A method for GPS (Global Positioning System) navigation on a device with GPS capabilities, comprising:
- receiving, at the device, input from a user corresponding to an intended destination;
determining whether current position information of the user is available; and
if the current position information of the user is determined to be not available, calculating a route to the intended destination based on a previously stored position of the user.

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. If the user is not on route, a new route may be recalculated based on the current position of the user, which became available. In preferred implementations, the system and method are implemented within the context of a GPS unit that is part of a telematics unit in a vehicle.
