There are several reasons you may receive the message "Can't Unlock Maps" on your nuvi, LIVE, zumo, Camper, RV, or dezl device. Please answer the following questions:

  • Can you touch OK and successfully search for points of interest and addresses?
  • Did you load maps to the device using the MapSource or MapInstall program?
  • Did you load maps to an SD data card?

If the answer to any of the above questions is yes, please follow the steps below to clear the "Can't Unlock Maps" message:1

  1. Remove SD card from device, if applicable.
  2. Plug the device into your computer with a compatible USB cable.
  3. Open the Garmin drive
    • This appears in My Computer or Computer on Windows
    • This appears on the Desktop on Mac
  4. Open the folder that contains supplemental maps
    • This is the Garmin folder on nuvi 200, 205, 300, 400, 500, 600, 700, 705, 800, 805, and 5000 series devices and zumo 400 and 500 series devices
    • This is the Map folder on all other nuvi, LIVE, zumo, and dezl devices
  5. Locate a file named gmapsupp.img2
  6. Right-Click and delete file named gmapsupp.img2
  7. Empty the Recycle Bin on your PC or the Trash on your Mac
  8. Safely disconnect your device from your computer to see if the "Can't Unlock Maps" message is gone.

1If you have a nuvi 55, 56, 65, 66, 2405, 2407, 2408, 2505, 2507, 2508, 2707, 2708, 3400, 3500, 3507, 3508 series, zumo 350, zumo 390, zumo 590, dezl 760, Camper 760, or RV 760 devices, contact Product Support instead of proceeding with these steps: http://www.garmin.com/us/support/contact

2On devices that use the Map folder, supplemental maps may have a different name. Please delete any other files that appear in this folder. On the series mentioned above that use the Garmin folder, please do NOT delete any files other than the gmapsupp.img file.

If the gmapsupp.img file does not appear in the Garmin folder, or if the answer to all three questions at the beginning of this article is "no," please create an unlock file for the device by following the steps outlined in the following article: https://buy.garmin.com/support/searchSupport/case.faces?caseId={c6b5ca80-6a30-11dd-59a9-000000000000}

If you have a nuvi 800 or 805 series, please see the steps in the following article: http://support.garmin.com/support/searchSupport/case.faces?caseId={7e0de640-b92a-11e0-e189-000000000000}
