yes huff is right. the dvd map is regionalized and will only play in its european region equipment hence the b in front of the 7003 insead of e which is north amaerica region. . it could be possible to copy the european firmware so the gps would respond but then insert the usa map data on the dual layer copy. that is what many owners are doing on the latest usa 6.1 toyota gps map they are copyng the 5.1 firmware and the 6.1 map that has lost its overide capability.
even more problematic is buying from a foriegn seller. at least with usa sellers your covered by paypals $1000 guarantee of delivery but doesnt cover foreign
ebay auctions.
