This site has to be the best....click on directions and fill in the origin and destinationWhere can I find mapping and driving directions inside of Mexico?
In addition to the Bing site, it is really wise to have a Mexican road atlas with you in the car. The Guia 'Roji can be found in large bookstores and on amazon.com. Really helpful when driving in Mexico.Where can I find mapping and driving directions inside of Mexico?
