You can use optional memory cards with the chartplotter. Map cards allow you to view high-resolution satellite imagery and aerial reference photos of ports, harbors, marinas, and other points of interest. You can use blank memory cards to record Garmin Quickdraw™ Contours mapping, record sonar (with a compatible transducer), transfer data such as waypoints and routes to another compatible chartplotter or a computer, and use the ActiveCaptain^® app.

This device supports up to a 32 GB microSD^® memory card, formatted to FAT32 with speed class 4 or higher. Use of an 8 GB or larger memory card with speed class 10 is recommended.
