Yesterday when I was listening some songs in my PSP I recognized that my GPS system had stop working. So for fixing this problem I had uninstalled the GPS software from my PSP and reinstall it again but even after that GPS system in PSP not working. I had also restored my PSP on the factory mode and turn it on and off for several times but problem still continued. SO I want to ask from you people that what now I need to do for fixing the problem completely? Any quick answer will be deeply appreciated.
