As you see the list is quite extensive with more info coming everyday.

That works, how often do they update?

All that is already on the new charts?

Tree Bass- we update daily so there is an update to the chart everyday, however that does not mean that there is an update on every lake daily, it means that there are changes made somewhere on the chart daily.

Chu chu- the updates are current to the day of production. To make syre you have the most current info it is best to update as soon as you purchase the new chart. For example if a chart has been on a dealer's shelf for a week, there could have been an update to your area that would not be on that particular chart.

thanks for the info

Navguy, Why is it that I can't update because I didn't log in after the first two months?

I didn't even know I had to do that.

My card is only 8 months old. This doesn't seem fair.

Yes, Navguy, why is it that even on the Navionics website it says "One Free Year of Updates" and no mention of two month limits?
