I have an Onix 8ci si combo, a blank 32 gb card, and the zeroline card. I see older units preserving their zeroline card space by mapping sonar to the blank card, then only transferring the converted map to the zeroline card. With the Onix, the AutoChart Live data can only be saved to zeroline. Does this make space management an issue? Should I map with only sonar data saved to the blank card, and not save AutoChart live data? Or does the software intelligently take this into consideration, and either purging the data after map completion or only maintaining a single copy of the data?
Also, can I copy the file structure to a spare card for the same Onix unit?
Maine maps are not that popular, so I have a need to create alot of private maps, and want to start with the proper storage management strategies.
Thanks..
