Silver includes coastlines, drying lines, all navigation aids, depth information up to 10 meters (30 ft), plus other information as recommended by international standards for safe navigation with a simplified, uncluttered chart. Navionics Silver is designed to be preloaded in some Chart Plotters to provide out-of-the-box navigational safety with an enhanced basemap. Only Silver and Gold offer All Australia on one card. Both Gold and Platinum Maps are available in two card sizes, which limit the chart area. Navionics offer three levels of chart detail known as Silver, Gold and Platinum. But, what’s the difference between Navionics Silver, Gold and Platinum Maps? That’s a question Rod Smith from C H Smith Marine in Collingwood (Vic) gets asked quite often.

Maybe I am doing something wrong.Navionics map cards are used in many of the popular brands of GPS/Plotters including Hummingbird, Lowrance, Raymarine, and Simrad. I'll seek some answers from Navico on these issues. Lowrance firmware appears to treat the 2 chart levels as separate rather than an additional overlay the way the Android app does. Strangely, you get the community edits in 'Navionics' charts and not on 'Navionics Fish 'N Chips'. So basically you need to swap back to 'Navionics' to use the chart effectively when viewing a larger area and swap to 'Navionics Fish 'N Chips' to zoom in. No community edits on any zoom level either. 26 foot contours and a few wreck markers. This detail only is visible on the lower zooms, which would be fine, but the higher zooms have almost no info on them. With the Navionics+ card in the 7 HDI, you need to select 'Navionics Fish 'N Chip' rather than 'Navionics' in the chart selection to get the finer contour detail. What I expected was basically what I get on my Android app - zoom in and you get finer contour lines from 'Sonar Charts' and communitiy edits (where people upload hot fishing places that they want you to go and so leave alone their secret places.) Zoom out and you get the normal Navionics detail. The result - well a little disappointing really. This could be a local PC config thing but I tried it on both mine.ģ. Sort of counter intuitive to normal USB practice. When it says 'Remove your card', it means remove the micro SD card from the adapter - not remove the whole shebang (like in the picture). Use the USB adapter included with the upgrade card. Do not use the SD card slot in your PC even though the pictures show this. So for $175 retail you buy a Navionics+ upgrade card which you download the maps onto over the Interweb using the current Gold card as validation. You can use your bundled Gold card - though I was concerned there was some fine print somewhere. Here's my experiences - hope it helps - any other input welcome.ġ. Recently took the plunge and upgraded to Navionics+ using the bundled Gold card I got with the sounder.
