Sony is to offer the GPS add-on for its PlayStation Portable gaming console to European users.

Set for release in early Spring, the Go!Explore system comprises an attachable GPS receiver and UMD disc containing the user's chosen maps including 3D models of cities.

The system has separate modes based on whether the user is on foot or in a car. In pedestrian mode, users will be able to plot their way through cities in 3D thanks to the fully modelled maps contained on the UMD discs.

Users will also be able to download new maps and upgrades via Sony's online PlayStation Network.

Go!Explore uses map data from TeleAtlas combined with navigation software from Nav N Go.

This addition marks part of Sony's drive to make the PSP a multifunction portable device, as seen with the recent inclusion of Skype calling from the PSP.

Map packs will be available for most European countries in English, German, French, Dutch, Spanish, Portuguese, Italian, Danish, Swedish, Norwegian and Finnish versions.

The Go!Explore kit will be provided in three bundle options:

GPS receiver and UMD (including maps of the relevant country) for €119
GPS receiver, UMD, Car Adaptor and Car Mount for €149
PSP, GPS receiver, UMD, Car Adaptor and Car Mount for €299
