    Every map version needs it's own jcv file.
    For City Navigator North America 2012.10 you need City Navigator North America 2012.10 .jcv

    I have a 1490T and just copied the Europe NT 2012.30 and the North America NT 2012.30 maps to my SD card, since they were too large to put them into the main drive.
    I then deleted the original map to create space on the main drive. The maps seem to work fine.
    Now my question: Both these maps came with JCV files, one is like 770MB the other 270MB of size and they are named D3060040A.JCV and D3084030A.JCV
    Since I now have enough space on the main drive, can I just copy both files into the JCV folder on the unit, or do I have to install them somewhere on the SD card?
    Also, can I have more of these JCV files in the same folder?
    Thanks for any help.
