Connect jQuery gmap plugin 3dParty/jquery.gmap.min.js to use google maps. And google map script http://maps.google.com/maps/api/js?sensor=false. Google map could be added into any block that has height and width (liquid or fixed). You can't need to use PI theme google maps css file. Add .pi-google-map class to block where you want to show Google Maps, then specify address and map type using data attributes data-map-type and data-map-address.
You can specify latitude and longitude instead of address using data-map-coords attribute separated by ";", example - data-map-coords="40.70502;-74.006344".
You can also specify map zoom and map style using data attribute data-map-zoom and data-map-style.
You can add your own marker by setting another attributes data-map-marker="imgPath.png", then you have to add another attribute with img dimensions data-map-marker-size="60,60" and one for anchor point coordinates data-map-marker-anchor="30,60".
Google Maps zoom on mouseWheel scroll is switched off by default, you can enable this by setting another attribute data-map-scroll-wheel="1".
You can specify additional addresses using both data-map-address and data-map-coords just add a number to attribute name like data-map-address2, data-map-address3, data-map-coords2 and so on...
You can specify data-marker-title="title 1", data-marker-title2="title 2" to add marker tooltips
