I have just got a consulting job that will make it necessary for me to drive in Mexico for three to six trips per year. I have asked my dealer about purchasing a DVD for the Navigation system for use in Mexico. He doesn't know if there is such a thing. Lexus, for some reason will not give me an answer.

What can I legally do that will allow me to use my navigation system in Mexico?

 

If the Nav disc doesn't cover Mexico, Then back in the day we had these large pieces of paper called "Maps." You may need to invest in one of those.
