Thanks for help… 
The card is FAT32 , file is unzipped and named gmapsupp.img, file is into the garmin folder on the SD card, which is accessable from a laptop via the usp connection…
The map doesn’t appear in the setup/map/configure maps, so can’t enable map… ??
Do I miss some settings somewwhere?
According to userguide it should be straight away… ??
