You can get that info from the Navteq website, www.navteq.com , latest version is 8P. Part # is 16-0075-904, price $199.00! That's right, $199.00....are they fucking kidding???? I can get a new mobile GPS for less. Why is the Nissan one $99.00? Same data but even that is outrageous. $29.99 is a reasonable price and something I'd be willing to pay. Alternatively there are copies of 8P out on the torrent websites if you are so inclined. This is exactly the type of gouging that drives people to obtain software illegally!
