This is where I am at. I've spent 3 seasons trying to get bathymetric charts on my Garmin 541s. Yesterday I received 2 folders from NCEI with the charts I want. Contained inside the folders was a note telling me I had to untar and uncompress the info. As of now I have about 18 hours in trying to do this! The files/folders are marked as .tar.gz\. When I get them untarred and uncompressed I hope to install them into Homeport then to the Garmin unit. Can anyone advise how I untar and uncompress the info as I have tried 7-Zip and a host of others all to no avail! Thank you, Bob
