While the rest of the world has been denied access to PSP's GPS accessory, Sony is releasing a more advanced version of Minna no Chizu, the GPS software, in Japan. The new software, which must be purchased in stores, includes some new features:
Petamap: a database of user-submitted points of interest.
PlaceEngine: software that determines your location based on nearby wi-fi points
Pedestrian navigation routes, which include shortcuts through parks, tunnels, etc.
Disaster relief centers: just in case.
