Default chart uploads

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

Thats a Unix extension. Google ".TAR.GZ" for instructions, programs, etc

Yrral3215, Thank you for the fast response! I did as you told me, however, after reading everything and attempting some of the things to untar and uncompress, I think the process is way beyond my mental capacity. Thanks again for trying to assist me. Bob

As an alternative to conversion , have you tried the Bluechart G2 Vision "Fish Eye " feature?

TTaxi, Thank you for the alternative. I think my unit has that built into it but I'm not sure. I'm going to the boat today so let me check. Thank you, Bob
