  1. Remove SD card from unit, if applicable.
  2. Plug the unit into your computer with a compatible USB cable.
  3. Open MyComputer/Computer icon. (Mac users skip this step.)
  4. Right-Click on the Garmin drive and select Open. (Mac users can locate the Garmin drive mounted on the Desktop.)
  5. Open the MAP folder.
  6. Locate a file named gmapsupp.img
  7. Right-Click and delete file named gmapsupp.img
  8. Empty the Recycle Bin on your PC or the Trash on your Mac
