No Sattelit

I've never understood why turning off the wlan switch would help. Can someone explain that?

Picked it up somewhere but haven't tried it myself. If it doesn't help nothing's lost

I turned the WLAN off but doesnt help. Why try another PSP? Is mit GPS Reveiver broken?

If you don't know what's wrong, you'll simply have to eliminate possibilities. If your receiver is indeed broken, it will also not work on another PSP. If it does, however, then your own PSP is probably "broke". (This may still be a key issue, search for Chilly Willy's Key Cleaner to solve that issue for PSP-290 receivers.)

Oh, what I said in the post above was a bit too simple. If it does work on another PSP, your own PSP may be at fault, not your GPS receiver.

Where can I get the Cleaner. Do you have a link?

I installed it but doesn´t work either =(

Put the program in GAME150 or GAME371 or try to change your kernel settings in recovery mode.

ich²: what exactly doesn't work? A simple "it doesn't work" really isn't enough. I think it'd be best to give an exact description of what you're doing. E.g.:
1. Put mapViewer directory in ms0:/PSP/GAME371/;
2. Changed system/config.txt to reflect my GPS receiver;
3. etc.

[ich²]

mapViewer is in ms0:/PSP/GAME371/

What should I edit in the Config File?

if you're using 0.5.20 version try to look in your config.txt for ENABLESERIALPORT, it must be 0 for psp-290..
