Which JCV is actually present in your zumo?

Thx for the link for the Dem map.
I'm living in the Netherlands so normaly i use the europian maps. But in June i travel to the states and thats why i want to have the north America map on my zumo. But i can't get the junction view too work. For the European map there is the D3048210A.jcv file on my Zumo. I have several JCV files for North America on my computer. But i don't know what file to use. I have, Full screen, lane assist full screen, medium and portraitfull and split screen. All for the 2017.1 map off North America

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.
