Cirocom GBSA and the Arduino

Hello,

So I stumbled across my dad's old Magellan Maestro GPS, and I decided to rip it apart. I stumbled across the GPS unit inside of it, and tore that out of the entire device (nothing's broken) and I did a little research on the chip. I found this http://www.cirocomm.com.tw/en1/pdf/antenna1/GBSA.pdf Based on this information, how do I interface it with my arduino? Thanks! --Andrew
