Hello! I'm new to HomePort and somewhat computer illiterate! I managed to copy the charts from my new EchoMap DV54 to an SD Card. I'm trying to copy the charts into HomePort. The charts do appear but when I remove the SD Card they disappear. Isn't there a way to keep them on the computer or do I always need the SD Card handy. Thanks for any help folks!
