Thanks, Dennis. I guess I really need to call Garmin. I am confised if I need anything else with it. My unit came with a world basemap with the ability to load other chart "bluewater", I think. In reading the description for Homeport it says that it doesnt come with charts loaded but, somewhere else it says it has a world basemap Hope all is ok with you and, IF I had some $ I would definitly consider taking the IKAT from you.
