Yep TomTom uses Tele Atlas for all of its maps with the exception of the RIDER which uses NAVTEQ maps. The new maps include 410,000 miles of new roads in the US and Canada and six million POIs which is really great. If you bought a TT 910, ONE or 510 during the Xmas holidays you would have really been getting a great deal b/c all of those products were $100 until the beginning of January and then they are having the free map upgrade on top of that.
