Does Iveco make a DVD player that plays all regions? ?

I work for the U.S. Army in Germany and our military community recently purchased 2 new Iveco bus with DVD players that play only region 2. Does Iveco make a DVD player that plays region 1,2,3,4,5 and 6? Can a qualify Iveco electronic technician change the region code from region 2 Europe to region 1 the United States. When the buses were ordered somebody in our organization failed to mention we need a player for region 2 or a player that plays all regions
