We are committed to providing updates for our marine cartography products. As updates become available, we will make every effort to ensure the areas of coverage for a given card remain the same. Updates may include new data or NTM (Notice to Mariners) changes.

New Chart Guarantee

When you purchase a new preloaded fixed-mount chartplotter, preprogrammed BlueChart® or preprogrammed LakeVü™ microSD™/SD™ card, you’re entitled to 1 free update¹ of the newest version of charts. Visit Marine Map Updates to get started. Updated charts will be for the same (or equivalent²) region as the original purchase.

Update Your Preloaded Maps

If your chartplotter came preloaded with BlueChart g2 or LakeVü HD maps, you can update your maps for the most accurate navigation.
