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.

From Post #1 by Paveli, according to Neil's suggestion, this I downloaded the locked image file for the Lower 49 States and unlocked it with gimgumlock. I put the SD card in my card slot, turned it on and, Voila!, this time it worked perfectly. Thanks Neil, you hit the nail on the head.
