Greetings Lionscribe, Thanks again for posting this Google maps integration details and code.
I have been testing it with great success, but have a question: have you or has anyone else figured out a way to specify both the Directions To and Directions From together as a single call? What I am trying to do is to launch GM with the From and To locations filled in, so that it goes ahead and caculates the route without further user input. Is that possible?
