In your google_javascript > wagmp_map_1 page you should do a search for this:
map.setCenter(point, 13);
replace it with this:
map.setCenter(point, 13, G_HYBRID_MAP);
This third parameter on the setCenter method will set the initial view type to hybrid. Make sure that you make a backup of the page first before you make this update in case you need to revert it.
