Dynamic determination of route conclusion before reaching destination

A method of providing navigation instructions in a vehicle, comprising:

• (a) initiating a navigation guidance session to a destination for the vehicle at a telematics unit installed to the vehicle;
• (b) determining that the vehicle has been parked in a parking location at a park time before the vehicle reaches the destination, the parking location being within a predetermined maximum distance of the destination;
• (c) determining that a user has left the vehicle while the vehicle is in the parking location;
• (d) in response to the determinations in steps (b) and (c), determining (1) a pedestrian travel distance from the parking location to the destination, and (2) a pedestrian travel time for the determined pedestrian travel distance;
• (e) detecting a vehicle restart;
• (f) determining a park time duration from at least the park time and the vehicle restart;
• and
• (g1) automatically continuing the navigation guidance session when the park time duration is less than the pedestrian travel time;
• and
• (g2) automatically terminating the navigation guidance session when the park time duration is at least equal to the pedestrian travel time.

A system for navigating a vehicle, comprising:

• a telematics unit installed in the vehicle and configured to provide a route to a destination to a vehicle user in a navigation guidance session;
• wherein the telematics unit is configured to determining that the vehicle has been parked in a parking location at a park time before the vehicle reaches the destination, the parking location being within a predetermined maximum distance of the destination;
• determine that a user has left the vehicle while the vehicle is in the parking location, determine a pedestrian travel distance from the parking location to the destination, and a pedestrian travel time for the determined pedestrian travel distance, detect a vehicle restart;
• and determine a park time duration from at least the park time and the vehicle restart;
• wherein the telematics unit continues the navigation guidance session when the park time duration is less than the pedestrian travel time, and the telematics unit terminates the navigation guidance session when the park time duration is at least equal to the pedestrian travel time.
