Humminbird Helix Basemap 1.031 , 2.280, and 2.440 Software Updates, Format SD card

Humminbird basemaps give you access to basic navigational information without having an additional chip. The new updates to the basemap are in a large zip file which is more challenging than conventional software updates. I have done lots of updates and this one was more complicated. There was limited information available so I wanted to help you with the process. This video will provide you with the information you will need to get the updates done.
