I was able to afford a GPS module from sparkfun ($60USD ouch!) to test out the GPS connection on my Phi-1 shield. It worked! The GPS is better than my cheap TomTom GPS, when I turned on both in my first-floor apartment. My GPS module worked and my TomTom is having hard time locking on the satellite signals. ![]()
Here is a picture:

I used the spec sheet on sparkfun when I was designing the space that the GPS would fit, right under the LCD. My hands was sweating when I made the boards. Guess what? My geometry works just fine ;D
Here you can see it fits very nicely underneath the LCD:

The light orange block is the GPS module
The LCD has a number of metal pieces that secure the display onto the PCB. The GPS just sits between four of these metal pieces ;D

Right now the program only displays the GPS coordinates on LCD. Since the Phi-1 shield has an EEPROM slot, I will update my codes to a logger once I finish.
Here's details on my blog:
