Enforcer, thanks for the reply, and the great plugin.
I've done a packet capture while I'm in RR and these are the packets generated when I hit the button for rrgas_gps:
I've highlighted where my zipcode is showing up in the packet, so it looks like the info is definitely coming back. I've obscured it a bit, but it is correct. I'm not exactly sure what you meant by "couldn't find the string that signifies the end". If this data is saved and read from a temp file, maybe I can check the file and see whats wrong. I'm not really sure what to check next.
