ABSTRACT:
An external storage device having navigation data and programs stored therein to perform a route search and provide route guidance, and a central processing unit which includes a program storage flash memory and program loading means for loading programs from the external storage device into the flash memory. The programs stored in the flash memory are run to perform a route search and provide route guidance. The central processing unit compares a version of each program stored in flash memory with a version of the program stored in external storage device, so that when the version of the program stored in the external storage device is more current than that stored in the flash memory, the program is loaded from the external storage device into the flash memory.
