This map is probably locked and you should either [Only registered and activated users can see links. ] or [Only registered and activated users can see links. ]. Just copy the map file directly to GPS unit or memory card. The path would in most cases be "[GPS or memory card]:\Garmin\gmapsupp.img".
This type of BlueChart g2 Vision charts is only really useful in Garmin chartplotters. nüvi road navigators and Garmin Mobile XT & PC would not be much useful to show a BlueChart g2 Vision chart.
