This procedure worked fine for my DNX5700BT.
I put 4 maps in the SD Card (inside Garmin folder) and I could select the desired map without any problem (CN South America, Tracksource Project, COCAR Brazil and Autoguia).
I also included the JCV file in the JCV Folder (inside Garmin Folder) and it worked too.
Just POIs were uploaded from a pen drive through the USB cable.

Hope to help you.
