This could be a beneficial help if someone can help me. I have a psp running 3.40 oe a, and I just purchased a holux m-1000. So if I get it working we can add it to the list of working gps's. I have gotten the green screen to work, and I read 8 satellites!!! but I can only get the gps 290 eboots to work on my psp. When I put the holux eboots on my psp I get an error. do I need something else to get it to work. I have the 3.40 accusb.prx, and gpsusb.prx files. I'm wondering if I don't need these for holux but I deleted them before and it still didn't work. someone please advise me thanks.
