I have an older Lowrance LCX 104C that I am taking off the boat to sell. I don’t have a lot of way points saved on it and I know how to delete all of them, but how do I delete all icons quickly? I have a ton of icons on it.
Do I need to take the lake master chip out before I do the delete or should I leave it in? The chip will be sold with the graph.
thanks in advance
