Take a clean SD card, make a folder on it called "Garmin", extract the file from the zipfile and place it into the new folder. The Chartplotter will find it as soon as you insert the card, but you will need to pan across to the map area unless you are already in the area !

The sample covers the Lower lake section and Corrib River, and will NOT run on the newer EchoMap units. Please contact AnglinCharts if you have a new EchoMap unit.
