NAVTEQ is a company that produces extremely expensive data DVDs ($200)that are inserted into a car's DVD player so that you can use them with the car's GPS system. The mapping data is on these DVDs. Because they are so expensive I attempted to clone the DVD so that I can have a duplicate and not use the original but protect it. However, when I inserted the duplicate DVD into the cars DVD player (Chrysler 300C), the disc was not recognized. I would like to clone this very expensive DVD as I don't have $200 to blow away. Your help is greatly appreciated! Thanks! GadgetDude P.S. This clone was attempted several months ago; before version 184.108.40.206.
