This does not belong to this thread but may be of interest to some people.
I got my hands on the factory manufactured cable, made specifically to connect PSP with Holux recevers.
I tested the cable with Holux GPSlim 236 and 240 units - works fine and looks much better than any of my hand-made cables. The cable can be acquired from vendors in both China and USA with a promt delivery. So if you consider using holux recevers (which seem to perform better than PSP-290) I stongly recomend getting one.

Using the 3.02+ fw prx modules seem to slightly speed up the satellite acquisition, as they "memorize" the latest known location and use for faster "warmup" next time. To generate 3.03 prx modules you'll need to use C+D psar dumper with 3.03 FW update psar and user "dump w/o decryption" option..
- GPS-290 support (dhaa :-)
- GPS info screen with satellite data
- Screen rotation in map mode
- Trip reset option added to menu. Trip data does not get reset when you switch to map mode.
- Fixed a bug in TRACK UP mode. (should not switch the mode when approaching to map's boundaries.
NOTE: some features, like gps data re-play & wifi-download are disabled in this version...
This version must be ran under 3.03 custom kernel!
It was briefly tested with 3.03 OE-B custom firmware, but may work with older custom FW version
(although installation may vary)
1) Copy mapViewer folder in to /PSP/GAME303/
2) Put usbacc.prx & usbgps.prx in MapViewer folder. Note that prx files are not supplied with this distribution.
I tested with usbacc.prx from 2.71 FW distribution and usbgps.prx bundled with Maplus software.
You can try using usbgps.prx from 2.71 FW, but it seems to have a problem reporting negative longitude;
so if you are in Europe and Asia it may work for you... (the 3.03 FW usbgsp.prx does not seem to work for me)
3) Generate a map for your area with gmdl tool and copy it inside the maps folder.
4) Attach the usb gps-290 accessory and you should be good to go...
added new variable to config.txt:
It should accept values 0,1,2 which may affect the initial satelite lookup algorithm..
Play with the values and see if it make any difference...
Special thanks to people who donated money and time to this project.
A few notes about the receiver:
The unit that I got from Play Asia seems to have a pretty bad sensitivity (compared to holux gpslim236). It would take ~5 minutes to get the first fix and frequently drop the connection. My holux receiver would connect withing 45 seconds and never drop the fix under the same conditions, scoring much better precision too.
Please let me know if you experience same problems with PSP-290....
