At first I was having a hard time looking for a plugin for google maps compatible with Joomla 3, until I found and tried to install this plugin. The way the parameters of the plugin is impressive as it will enabled you to vastly customize your map with a wide variety of parameters. It is very easy to use to. And overall, it provided exactly how we want to have our embedded maps look like.
The support to the product is excellent as well. I would higly recommend this plugin to anyone.
