Google Map API

Hello,
I'm trying to setup the map module. Currently in only shows up a realty in Ha Noi, Vietnam and not the realties that i've entered. I susspect it's a google map api configuration problem. Can you please inform me about the correct google maps api that I'll have to use, becouse there are about 10 of them n the Google Maps API page.

Thanks in advance

Michael
