Where am I, literally?

The uM-FPU's are up and running and so is my GPS receiver. I used the NMEA sentence application note on the micromega website as the basis for a user defined function inside my uM-FPU. The function collects a PUBX, 00 NMEA sentance from the GPS receiver and breaks down it's fields to be stored into the registers of the uM-FPU. The code is working when I load a test sentence into the uM-FPU manually, but there is an unknown problem getting the actual data from the GPS receiver into the uM-FPU. It's getting a bit late, so I decided to find the problem tomorrow. Below are some pictures of the output with the test sentence and the output of my GPS receiver. I'm right on track for my XML output at the end of the week.
