Finally, my PSP may actually become useful! This is a "simple" way to connect a GPS adapter to your PSP. It costs around $130, so it is a bit cheaper than most other GPS units. Here is what you need:
• Holux GPSlim236 (~$100)
• Intec G6704 PSP Remote Control (~$11). Alternatively you can rip the connector of your original remote control.
• USB (Mini B) cable ($5-10) (don't use the included USB power cable)
• 1K 1/4watt resistor (>$1)
• Electric tape ($2 roll)
Bust out the soldering gun and follow the somewhat complicated instructions that the guys at Deniska's have put together. Sounds like a nice little project, especially if you happen to be one of the many PSP owners who have retired the PSP for lack of good use—like myself. Thanks, wraggster.
