Abstract
A method of assisting a user of a personal navigation device with automatically selecting a route after the personal navigation device transitions from driving mode to walking mode includes detecting a mode transition in the personal navigation device from driving mode to walking mode, recording a vehicle location where the mode transition from driving mode to walking mode occurs, receiving a request from the user to create navigation instructions to a destination location, determining a distance from the current location to the destination location, and guiding the user back to the vehicle location by providing walking instructions with the personal navigation device when the distance from the current location to the destination location is greater than or equal to a threshold distance and then guiding the user to the destination location by providing driving instructions with the personal navigation device.
