Thread: City Navigator North America NT 2017.10

I find the unlocked image file of North America map works,
but the unlocked image file of lower 49 states does not work.

Im seeking for the DEM img North America suitable for the zumo 590. Anyone?? Would be great.
Pls tell me what jcv file to use for the ZUMO 590.

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

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.

The lower 49 states worked for my nuvi 255w without any issues.
