Hello all, I ordered a navigation module from Europe to replace the one that messed up in my car. The only one I found was from Europe. When I installed it everything seemed to work great... the only thing is that it was reading a map in Europe. I removed the Europe DVD and inserted the US DVD. It reads it but it places me somewhere in a large body of water. I can set it to my state but no roads show up... just water. Does the navigation module also have to be from the US?...
