GPS on your PSP

PSP Updates has a guide on turning your PSP into a GPS navigation system. Don’t be frightened by the amount of circuit diagrams as there are ample pictures to guide you along. The GPS software runs under LUAplayer version 0.11 or later and must be installed after upgrading the PSP’s firmware to 1.50. Pretty neat stuff, but as its still under development there are still some bugs to iron out. Forums via PSP Updates
