I'm trying to update my Solix software. Current version is 3.0. Latest version showing on My Humminbird for my unit is 3.110. It says in the download instructions that 3.040 must be installed first in order for 3.110 to download properly. My Humminbird is not offering me 3.040 as a download option and I can't find it anywhere. How do I download 3.040 if Humminbird isn't showing it as an available download for me?
