Updating navionics cards

Rated 4.56/5 based on 942 customer reviews

Now, recognise that a Navionics Gold chart covers a greater area than a single Admiralty Chart Pack and suddenly, in comparison, it doesn't sound quite so bad.

At the end of the day a Navionics "upgrade" is really a new set of charts.

And now that you can download updates from the net and update the charts yourself from a PC its going to get even cheaper. When I bought a new Navionics chart it didn't show the causeway to Eriskay, or the bridge to Scalpay, both of which had been in existence for about ten years, at the time.

As a bonus, it showed an island in Loch Scavaig which doesn't exist, so I suppose I got something for nothing.

Only I do not understand why they charge 100 for a simple update which I believe should be free for at least the first five years. Put it in the context of the publication of a new (paper) Admiralty Chart Pack for your region (RRP about 45).Older chart plotters, up to about 2013, sometimes used Compact Flash (CF) media cards.Other chart plotters us either a SD card or a micro SD card that may plug into a "sleeve" with SD card dimensions.One type of card will not fit into a chart plotter's card slot designed for the other type of media card.To see whether a Navionics card is compatible with your plotter model and to remind you whether you need micro SD / SD or CF card format, see the PDF files linked from this page: The exception to the "same card type" rule is when you are retiring an old CF card using chart plotter and deploying a new plotter that uses micro SD / SD card.
