The GPS device will load map data from an included UMD that's region specific. Updated or additional country maps can be purchased and downloaded to a Memory Stick. The GPS will work with the older/original PlayStation Portable as well as the newer PSP-2000. Pretty amazing that the Sony PSP can now do gaming (obviously), Skype calls, and now GPS. The large screen should do nicely with GPS navigation, so TomTom and Garmin may need to be concerned since they are mostly one-trick GPS ponies. Though I doubt the first rev of the Sony PSP GPS software will include turn-by-turn text-to-speech naming of streets.
