Are you looking to update a Navionics Gold or HotMaps premium chart, but don't know how?
Are you also stuck between two different fishing areas and need to buy more than one Navionics chart?
They just released a new update chart called navionicsupdates. this sells for around $100. it expands the area of coverage for anywhere in the US and Canada and gives you the latest charts. You need the old chart to enable the update chart to work.
