I spent an hour or so in the archives and didn't find what I was looking for.Between Navtronics and C-Map which do you prefer?Should the compatible software be a factor in choosing a chartplotter?From what I can find on the net, both Navtronics Platinum and C-Max+ have about the same features. Is there anything that makes one company stand apart from the other? The only feature that C-Max has that is not listed for the Navtronics is animated light signals.In other words, do I pick a charting system, then find the chartplotter I like that uses that system? Or, do I choose the chartplotter I like and not worry about what system it uses?Garmin is not an option, my PC based software cannot use their format.
