Updating a non-Navionics Card
Quick answer: Yes.
Regardless of what you have in your plotter right -- LakeVu, BlueChart, Insight, Navionics Gold, Hot Maps Premium, Land and Sea, etc. -- there is a way to turn that chip into a Navionics+, with all the one-foot contours, ability to update and all the other cool features. The tricky part is how to get there, and that depends on the card.
Here is a link that explains it all in great detail: https://navionics.secure.force.com/kb/pkb_mobile#/articles/en_US/Knowledge_Article/Can-my-plotter-card-be-updated
And here is the information from that link, in case you don't want to click:
If you are using a Navionics Marine Gold, HotMaps Premium, Marine & Lakes USA, or Land and Sea Gold:
You can upgrade to Navionics+ online through our Chart Installer or by purchasing a Navionics Updates card*. You may be prompted to purchase a new Navionics Updates card if your current card was produced before the Freshest Data program began. This card can be purchased through our online store or your local dealer. Pricing of the upgrade varies depending on the coverage area selected for your new download. Simply install the Chart Installer and plug in your card when prompted to find pricing information for your region. The Navionics Updates card pricing will also vary upon the region purchased.
For Navionics+, Platinum+ or HotMaps Platinum:
You can update online at 50% off the list price of the chart for another year of Freshest Data updates. Plug your card into your computer to launch the Chart Installer and follow the prompts to renew your subscription and update your chart. Navionics+ chart owners may find a slight difference in pricing if selecting a different chart region. Platinum products produced before June 2010, are not eligible for Freshest Data updates and will require a new chart purchase through your local dealer.
Platinum+ update (procedure not available for North and South America)
If you update your Platinum+ online through our Chart Installer you will update only the 2D charts.
To update also 3D charts you need to go to the nearest local dealer, give back your old Platinum+ and ask for a new one that will be given you at half of its original price.
For Plotter Bundle cards (cards pre-packaged with select GPS plotters/sounders):
You can upgrade to Navionics+ online through our Chart Installer or by purchasing a Navionics Updates card through our online store or your local dealer.
For Navionics' competitor cards:
Don't have a Navionics card but have a card from one of our competitors? The Chart Installer now allows certain competitor cards to activate Navionics Updates cards purchased through our online store or your local dealer. Below is a list of accepted competitor cards.
