What you need is the Navionics+. Once you got home with youre new card start by deleting(purge) everything then download the region you intent to fish.
Why deleting everything? Its to help the processor working a little faster. If you leave everything US & Canada Nautical charts this is to much for the Elite processor.
Don't download a "region", only the individual waters you fish.
