Sorry its been a while, been busy working with other things.
The LS20031 is TTL, and not RS-232. So you will not be able to send it out directly to the PC. You will need something like a max232, or an equivalent to invert the signal levels.

Your PIC should be able to receive the TTL at 3.3v, even though I am guessing the PIC is at 5v. Just don't TX from the PIC to the GPS without a level shifter.
Thanks for the info...one more question, I don't have 20Mz crystal, but I do have 20.945 Cyrstal, can I use it?

thanks in advance,
