Memory Cards

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.

The memory card slots for all GPSMAP® 9000 series chartplotters are located on the back of the device and are compatible with microSD® memory cards.

The capacity of the memory card depends on the memory card format:
  • FAT32 = up to 32 GB
  • exFAT = up to 1 TB

As of software version 34.00, the internal card readers support up to 1 TB microSD memory cards, formatted to exFAT with speed class 10 or higher. Use of an 8 GB or larger memory card with speed class 10 is recommended.

NOTE: When you insert a new memory card into the chartplotter or connected card reader, the chartplotter starts writing private information onto the newly-added card.
