Have you purchased a Navionics card before and just stuck it in your unit with out registering the card? Don't forget when you purchase a Navionics card you have to activate it on Navionics website to get the year free of software updates. From there you can update all the latest Nautical Charts, SonarCharts and community edits. If you have any questions regarding how to do this process feel free to contact me.![]()
