ABSTRACT:
A portable navigation device is provided that includes a receiver configured to receive signals from GPS satellites. The device includes memory that stores a non-navigation application and non-navigation information related to the non-navigation application. A user interface is configured to enable an operator to enter non-navigation instructions related to the non-navigation application. The a processor module is provided that calculates a position of the device based on the signals from the GPS satellites. The processor module implements the non-navigation application and performs non-navigation operations defined by the non-navigation application based on the non-navigation instructions entered by the user. The processor module disables the non-navigation application after a predetermined trial period of time following a start time unless and until an application access code is entered. Optionally, a cartridge they may be included that is configured to receive an application access cartridge containing the application access code. The code indicates that access to the non-navigation application has been purchased by the user of the device. The processor module enables the non-navigation application when the application access cartridge is entered into the cartridge bay with a valid code. The processor may not disable the non-navigation application, such as when an application access code is incurred before and in of the predetermined trial period of time.
