With Google Custom Maps PRO, You can change the whole appearance of the Google Maps by changing the color of Water, Road, Landscape & many more, as well as add a Custom Marker Point on the Map and also add Custom Info Content. If you want a little more control over the maps you can also type the custom code which you can generate either from www.snazzymaps.com which has tons of readymade presets OR create your own from Google Maps Styler.
