I know that humminbird now has 6.300 available for the 798ci Si. I have not done a good job of saving my old files but now I might want to downgrade from 6.300 to the latest before that. I see in the download section we have 5.840 and 6.300. Is 5.840 really the last version before 6.300? I tried piecing the information together from the humminbird faq but its not clear what code version is intended for what equipment, so thought I would ask. Ideally looking for a list of the code that could be run on a 798ci si.
Am looking for the same information for the 778c, if anyone knows where that can be found.
thanks
