The PSP-290 GPS Receiver is fairly small. It attaches to the USB port on top of the PSP and is held in place with two screws. The antenna can be placed in several positions whether it be up or closed. Using Deniska's MapThis! app, it takes about anywhere from 30 seconds to a couple of minutes for the GPS Receiver to lock on to some satellites depending on your location. Also, considering MapThis! is not by Sony, there will be some issues but Deniska is working hard, day and night to resolve issues.
