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.
