I have the exact same problem with the Lower 49 States that I downloaded from and posted about the problem on another forum. I get an error message popup that reads, "Detailed Maps are required for routing. No detailed maps are found on this unit." The full image file works fine but I believe the Lower 49 States map image file is corrupted. I downloaded the unlocked map file twice and I had the same problem with both downloads.
