How can I Get detailed driving directions from Toronto Ontario to Central America (Panama City, Panama)?

I might take a road trip to Panama City in Panama Central America- we would leave from Toronto! I can't find anything on the website that lets you get detailed driving directions! I tried using MapQuest- but they only let you pick destinations from Canada to United States...Anyone know of ANY kind of website we can use to navigate this LONG road trip?? :)

Wow that would be a long trip.. like 4 days.. U should better take a plane man, it would be cheaper and easier
