Navigation device and method
First Claim
1. A method of providing a logging function in a personal navigation device, the method comprising the steps of storing information relating to current position and time-specific information relating to said current position in a non-volatile memory of the device to create a logfile, said step of storing occurring only when one of a specified set of events occurs, said set of events being at least one of:
- user-specification of an spatial, temporal or device event, calculation of a new route, deviation from a calculated route, recalculation of a new route, reaching a destination, powering the device on and/or off, arriving at or departing from any favorite or recent location stored in the memory of the device, deviation of the device from the current direction and road along which the device is traveling.

Abstract
A method of providing a logging function in a portable navigation device and a portable device adapted to provide such a function are described. The method includes the step of storing location information relating to current position and time-specific information relating to a current position in a non-volatile memory of the device to create a log. The storage of such information only occurs when one of a specified set of events occurs, the set of events being specific to either a navigation mode or a free-driving mode of operation of the device.

9. A personal navigation device for providing a logging function, the personal navigation device comprising means for storing information relating to current position and time-specific information relating to said current position in a non-volatile memory of the device to create a log file, said means for storing occurring only when one of a specified set of events occurs, said set of events being at least one of:
- user-specification of an spatial, temporal or device event, calculation of a new route, deviation from a calculated route, recalculation of a new route, reaching a destination, powering the device on and/or off, arriving at or departing from any favorite or recent location stored in the memory of the device, deviation of the device from the current direction and road along which the device is traveling.
