I would start by finding technical documentation for the GPS which explains what these pins are for and also explains serial codes which can be sent and what serial codes would be received via these pins.

Then decide what codes you want to send. What information you want to receive.

And the electrical requirements for these pins.

I know I have a cell phone which comes with instructions for the consumer on how to use it. My cell phone also has electrical connections and these are not documented in this instruction manual other than "plug this or that into that jack".

But somewhere else out in the world is detailed technical documentation as to what the pins are for and what all these pins can be used for.

Good question....I tried Bs2 testprogram for Parallax GPS module...It worked in about 5 secounds:) But the qustion is where do i connect my bs2 and which signaltype(RS-232, TTL or something else) does it use? Does enyone else have a datacheet for SiRFGSC3e LP chip? can i desolder it from the gps reciever and attach it to a breadbord an use it with other components?

THX for answers!!!
