1. A method for routing using a positioning device and a map having a plurality of segments the method comprising:
- generating a first route from a first location to a second location;
generating signals to provide directions along the first route using positioning information from the positioning device;
detecting that the positioning device is off-route at a third location, the third location being adjacent to the first route and the third location representing an entrance to a parking lot; and
generating a second route by tracking the position of the positioning device from the third location to a fourth location located near the second location, the fourth location representing a parking spot of a parked vehicle within the parking lot and being on one of the plurality of segments of the map.

Abstract
A method and apparatus for routing using a positioning device and a map having a plurality of segments; generating a first route from a first location to a second location; generating signals to provide directions along the first route using positioning information from the positioning device; detecting that the positioning device is off-route at a third location, the third location being adjacent to the first route; generating a second route by tracking the position of the positioning device from the third location to to a fourth location, and, in some cases, storing the second route for use in route generation.
