Since Steve Sipe and I have similarly equipped vessels, and he has been so much help before, this is probably mostly a question for him; but on the chance there are others with answers, here goes... At present, I can transfer Coastal Explorer routes and waypoints on my laptop directly to my elderly Furuno 1920C plotter via a Furuno data cable. As a quick backup so I don't need the laptop handy, I can also save all such user data to an SD card inserted into the Furuno. I am interested to know if there is software supporting transfer of the same data from the laptop to an SD card for subsequent upload into the Furuno. When I was Garmin equipped, I could accomplish this feat using their Homeport software. I know that contrary to the Garmin equipment I head, my Furuno plotter overwrites all its internal data when uploading from cards and computers, and I plan to have several SD cards aboard with different sets of data.

Rich, I may be mistaken, but I believe that the data written by the Furuno is proprietary and can't be manipulated or read by anything other than the Furuno software. I recall a conversation with Furuno support where I posed the same question to them, and that was basically their response. Additionally, they said the Furuno PC software ( "MaxSea Time Zero" can work with the data directly, reading and writing to an SD card that can in turn be read by the VX2 chartplotter. I believe that Time Zero can also be connected as a network node on the VX2 network via ethernet connection. The software lists for $495. I don't have first hand experience with TimeZero, my knowledge comes from what I researched on their website. So your plan to use multiple SD cards may be the most workable solution. Hope that helps.
