hello, I have buy a 2004 rx with the Nav but I have also the old version of the DVD. I live in Quebec, Canada and, except montreal and quebec, I have no road and no city and I have check in the newest version of the DVD and I have all the information that I need but it's outrageous, ridiculous to sell a DVD 200$ before shipping than I want to know, can I use a copy of an original DVD in my rx8 without modification and, does somebody here is ready to sell me a copy ???? thanks for your help
