Help with GP-2106 Eval Board and Ardunio

I cannot find any information about how to hook this thing up to an arduino.

It has 6 pins..

ON/OFF (All this does if connected to arduino is kill the power to the arduino if i press it and restores power on release)
GND (i got this)
VCC (hooked into 5v)
RX (hooked into TX1 [Pin18 on Mega2560])
TX (hooked into RX1 [Pin19 on Mega2560])
PPS (for providing a clock based on GPS time)

I cannot for the damn life of me get this silly thing to power up and transmit at all.

i bought the GPS and the eval board from sparkfun. They offer no support or examples. Every other product has examples except this one.

I'm quite new so go easy on me please. I know its just something stupid staring me in the face but i cant see it.

Found the problem...

The arduino Mega has pins marked TX and RX and none of them are the TX/RX pins i need to use. I needed to use pin 10 to receive from the GPS.

I knew it was something stupid.
