SD Card Not Detected, Recognized, or Incompatible in Garmin Express

Garmin Express may display an SD card as incompatible or fail to detect the SD card if there is a problem with the card or the computer's USB configuration. 

NOTE: You may need to restart your computer to install any computer updates before performing the steps below.

1. Ensure Garmin Express is up to date.

2. Verify the SD card is within the size limits and has sufficient available space for the update. See SD Memory Card Sizes for Automotive Devices.

3. Ensure the card is inserted into the Garmin device and is pushed in all the way. Some devices have a spring-loaded slot that will click softly when the card is fully inserted. Garmin Express will not detect SD cards inserted into a separate memory card reader.

4. Take steps to ensure the computer's USB configuration is as simple as possible:

• • Do not use a USB hub or extension cable.
  • Use the USB ports on the back of the computer if using a desktop computer.
  • Unplug all USB devices except for the mouse and keyboard (including the Garmin device), reboot the computer, and try again.

5. Try a different USB port on the computer.

6. Format the memory card

7. Try using a different SD card.

8. Run Garmin Express as an administrator.

9. Run Garmin Express on a different computer.

• • If using a Mac computer, you can try a different Admin User before trying another computer.
  • Contact Apple for instructions.

A functioning SD card should be detected if these troubleshooting steps are taken.
