GPS psp-290 doesn't work?

The information are all there if you searched. It really is simple and easy if you get te right information.

The problem is there are TOO MANY information and tutorials spread around from many sites spanning a long time.

I wish there is an OFFICIAL site with the latest files and installation instructions so people would not waste so much time doing the wrong things!
