If I don't know what downloads have been done on my units (I have a 797 and 788 that were on a boat I purchased)...should I just download the most recent on a card and put it in the units and turn it on... OR, should I download all the updates and put them in?

I would go ahead and download the latest software that is listed on Humminbird.com.
