Every time when I connect the Navigator IV to the USB socket I recieve a strange error.

>>>> /Garmin/mac-basecamp-3.0.2-source/libs/MPL/impl/MPL_MapsDatabaseCard.cpp:178
No maps found in image
Images: /volumes/garmin/garmin/garmin/gmapbmap.img <<<<


I looked everywhere but can't find the solution to solve this.
Enclosed an screenprint from the Garmin directory.

Please help.
