zumo 396 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.

1. Ensure Garmin Express is up to date.

2. Make sure the SD card is fully inserted. The brass pins should be fully covered by the card. Garmin Express will not work with a separate memory card reader.

• • Do not use a USB hub or extension cable.

  • Use the USB ports on the back of the desktop computer.

4. Unplug all USB devices (except for the mouse and keyboard), reboot the computer, and connect 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.
