Now I think I may see the problem. I will assume your GPS unit sends data at 4800?
Here is a snippet from one of my programs. No 232 chip.

SERIN2 PORTB.1,16572,[WAIT("$GPGGA"),WAIT(","),DEC2 H,DEC2 M,DEC2 S,_

        WAIT(","),DEC2 ND,DEC2 NM,WAIT("."),DEC3 NMD,WAIT(",N,"),_

        DEC3 WD,DEC2 WM,WAIT("."),DEC3 WMD]

according to the datasheet its 9600


would my test code work tho were i input the next 6 characters afer "GPGGA"

then use serout2 str gps_data\6] would str gps_data\6 show the next 6 characters even it was a comma or dollar sign etc?

It should work.
can you post the data sheet for the GPS module you are using

Hi,

As it runs off 3.3v here is a PDF on interfacing it. Hope it helps.
