GPS PSP-290 GPS State OFF

[mcbchild]

I have the same issue with my FAT PSP. I installed mapviewer v5.05b, my board is TA 079/81, GPS-290 and Mapviewer is in my GAME317 folder, I am running 3.71 CFW. I dumped my keys to the ms and analyzed keys with Keycleaner 1.4 and all keys are okay. i still see GPS State OFF in the GPS info screen. put the ms in my co-worker's slim psp TA-085 and plug the gps 290 on his and it all works great. The I hook the ms and the gps-290 back to my unit and GPS State On shows but then goes back to GPS State OFF after a few minutes. Any help would be appreciated.

Try cleaning the metal contacts on either side of the usb port on the PSP. The metal prongs on the receiver might not be making sufficient contact.
