Plot a route on a "real" (Google Maps) map.

Hi there

I've been asked to show the locations a user has been to and then show the route on a map. I know there are a few plugins out there that allow the use of google maps in Unity but from my research none of them indicate whether I'd be able to plot a line from one set of GPS Coordinates to another.

So my question is...is there a plugin, API or anything else out there that you have experience with or may just have heard of that will allow me to plot GPS positions in unity?
