Thread: Downloaded maps don't showing on device

I have downloaded few custom maps and tested each individually they all working fine, now i installed 32GB MicroSD card formatted with Fat 32 and put all maps on it together total 18 maps.

And my unit GPSMAP 62sc only shows 4 maps out of 18 i had on card.
Then i moved this cards outside of "Garmin" folder on card and it started to show another 6 maps that it was not showing earlier.

Is there limit on how many maps i can have at same time trough SD Card?

Also i had message "Cannot unlock maps" on startup when it displayed 6 maps, could it be when there is error in file name or activation unit stops loading subsequent maps?

P.S. Also i installed patched firmware for JNX support.

EDIT: after tossing some maps around i managed to load 9 cannot load more than that.

Also if i to copy any of TOPO US 24K maps on memory card, then they load over all other maps on the card.
