x-Radar integration allows individuals to interface with Sony Style’s Petamap service which provides social mapping services to internet connected devices including PSPs, PCs and navigation devices. Users can find the locations of cafe’s, noodle shops, or places of interest that have been tagged to the map.
After a connection is made via WLAN to obtain the map, utilizing the “Place Engine” the current location is identified via the WLAN or GPS. Users can then hone in on their destination. Data such as the type of location, type of food served, etc… can all be viewed on the PSP.
