Dave, Jesse,

I can see in the robostix 4 pins with the following:
Atmel I2C
G    TX    V     RX
You mean just connecting approperly the SDA/SCL from the gpsstix to TX/RX will do the trick?
Are in this case the G and V needed to be connected?, or that is only for powering other possible I2C devices??
This is getting more and more exciting every day, thank you guys :D
cheers

Rodrigo
