    The only reason this would come up is if you tried to update your map and don't have the unlock code. Please see this link:

    Please explain what you did prior to this happening. It would not happen on its own unless you deleted the unlock code file.

SOURCE: Cant unlock maps

What is the Garmin 510 that can't unlock maps stating exactly? And to Nici07 who said, "Need to unlock device", are you referring to a PIN lock or locked maps?

SOURCE: My garmin says it can't

If you are getting a Can't Unlock Maps message, you have a problem with the map unlock code on your unit. If your Garmin is not a preloaded device, you may need to verify that you are using the correct unlock code and re-install your mapping software.

If your GPS is a preloaded device, such as a nüvi, or if you cannot get this issue fixed with this information, please call Garmin at 1-800-800-1020 for further troubleshooting.

Here's your options:

1. Enter the correct PIN.
2. Go to the secure location where the PIN was set and it won't ask you for a PIN.
3. Send the unit back to Garmin to be unlocked.

Sorry but there is no master reset. The PIN is written into memory that can not be erased. I have had success in unlocking Nuvi's but I will only do it for people who have a valid purchase receipt from a major retail chain and if they can provide me with their Garmin registration info so I can verify that they are the rightful owner.

There are too many of these units out there that are stolen and the culprits are looking for a way to bypass the PIN. This is why Garmin added this feature to their GPS's.

The only way to get this unlocked is to send it back to garmin with proof of purchase. Reason is that these items are commonly stolen and Garmin does not want to support criminal activity.

Cannot unlock the maps in my garminedge 705. When i turn unit on message comes up cannot unlock maps


Information on unlocking garmin maps can be found at http://www.fixya.com/support/r6197735-no_detailed_maps_found_support_routing

There's more information there than you need since the article is about garmin nuvi satnavs that display a message "No detailed maps found that support routing" but part of the article deals with locked maps. The principle is the same for the garmin Edge but you'll need to skip to the part that deals with unlocking maps.

Gps has lost its maps, screen says can't unlock maps


There several reasons you may receive the message Can't Unlock Maps on your nuvi or zumo device.
  • Can you press OK and get to the Where To/View map screen?
  • Did you load maps to the unit using the MapSource or MapInstall program?
  • Did you load maps to an SD data card?

If one of the points above applies to you, please follow the steps below to clear the Can't Unlock Maps message:
  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 Garmin folder.1
  6. Locate a file named gmapsupp.img
  7. Right-Click and delete file named gmapsupp.img
  8. Safely disconnect your unit from your computer to see if the Can't Unlock Maps message is gone.

1. Nuvi 1100/1200/1300/1400/1600/3700 and Zumo 665 users will open the Map folder instead.

*If the gmapsupp.img file does not appear in the Garmin folder, please create an unlock file for device.

Garmin NUVI 205 when turned on says can't unlock maps!?!


Whenever Garmin Nuvis have map problems, I recommend performing a hard reset of your Gamin Nuvi 205. Also, use Garmin's WebUpdater service to make sure you have the latest software on your device.

I hope that helps.
