I was looking for it myself...I actually found it on torrent site. I downloaded it and burned it per instructions on Dual Layer Disc and it worked perfectly. If you would like to actually purchase a copy, you can get it from www.navteq.com
walker is right a google search will find it for you and from a torrent site. it has the latest and greatest copy. and you will need a dual later dvd, its 7.4gb a standard dvd holes 4.7gb it will not burn to that so you need a duel layer dvd that holes 8.5gbs
