problem w 4.01 m33-2

So I'm running the firmware mentioned in the title
I have mapthis v0.5.20 and the sony gps 290
I've tried all kind of things (including extracting and adding the prx files manually) but I won't see my position on the map.
It says gps state ON but all the other fields are zeros. Also it shows cpu clock 110.
I don't know what else to do
Please help

Have you read the Map This! wiki book? It's in one of the stickies. That should tell you it can take a while to get a fix, so stay still, and have plenty of visible air around (tall buildings are disaster...)
