First, who did you call? If you called expansys.com or expansys-usa.com they have no understanding of Wayfinder or Navicore and how the license will work with your internet tablet. They told me the same thing, that it would work in the US. So I got it, and when it arrived I loaded up my N810's map application and entered in the license key. It worked great except one thing... It's ONLY for Northern Europe. So when I try to use it for turn-by-turn when I'm in the US a new license box pops up requiring a license for the US. So without a US (or Northern America license) it will not do turn-by-turn. Second, the map software is the same for a N8x0 that was purchased in Europe or the US. The only difference is the actual maps that are stored on your device. So if you are strictly buying this kit from expansys for the satnav license in hopes to use it anywhere in the US (or Canada, Southern Europe, etc) then you're wasting your $ If you reside in Northern Europe or plan on traveling to Northern Europe then great... you got a cheap license for your NIT for using in Northern Europe. jbk
