Outdoor and Marine Handheld Interface and SD Memory Card Requirements

Newer Garmin® outdoor handhelds will mount to the computer so that the internal memory can be easily accessed (this is typically known as a mass storage interface) and many older and newer models include an expandable memory slot. The internal memory and an installed SD or microSD card can be used to store the following:

• Additional mapping

• BirdsEye imagery

• Photos (on devices with a camera)

• GPX files including geocaches, waypoints, routes and tracks

As long as the device has the latest version of software, it can use the maximum card size from the tables below. For specific instructions on updating your handheld, see - Help with Product Updates.

Key Items Regarding the Information in the Tables Below

• Interface Options include:

  • Mass Storage: Can access internal memory.

  • MTP: Can access internal memory on Windows, but not on Mac.

  • Garmin Mode: Cannot access internal memory.

• When using a card with a larger capacity, if there are too many files and/or large files on the card, the device may draw maps more slowly.

• There may be other file limitations that apply to your device. For more information, refer to the section below.
