How to get info panel to give driving directions using address instead of latitude/longitude?

[jmelto...@gmail.com]

I am sharing a map I created with 84 markers. However, when a user clicks a marker the info box that is brought up has a link for driving directions to that location. When the user clicks the link, the driving direction page is loaded and the user can enter their address to get directions. However, the directions are for the marker's longitude and latitude. I'd like the directions to show the actual physical address (which is available data - it's listed in the info panel for each marker). How do I do this?

Thanks!
