I ordered a update for my Raymarine
Dragonfly 7 chart plotter. I assumed the Lighthouse NC2 "Electronic Navigational Chart" (North America) was what I needed. The Raymarine
site ad wasn't specific about what this chip worked with and when I installed it on the front end of a 4 day trip, I discovered my chart plotter had maps but no water depth
. I re-installed my old chip and made the trip.
I called Raymarine when I completed the trip and was told the Lighthouse NC2 chip wouldn't work
on my chart plotter (you think?). They weren't interested in my returning the once used chip and basically said "grin and bear it".
The packaging states "Simply Superior" but I found it less than Simply Superior.
Anyway, if you can use this chip, it's available and up to date as of July, 2020. I have no idea what this works with but know it doesn't work
with their Dragonfly 7 plotter.
