You will need to input the security code for the maps. If you purchased them through Garmin or a Garmin dealer, contact Garmin and they will give you the security code.

When i switch on my garmin c510 it tells me i cant unlock maps how do i solve this problem


Details on unlocking maps for Garmin Nuvi satnavs are at http://www.fixya.com/support/r6197735-no_detailed_maps_found_support_routing
StreetPilot satnavs probably use the same method. You may need to skip to paragraph 2 and start from there.

To retrieve unlock codes you need to have your satnav registered with garmin.

Follow the prompts. You'll be asked to create a username and password. Write them down and keep them safe. You'll need them anytime you need to update your maps or solve problems in the future.

Retrieving your unlock codes:
  1. Log into your myGarmin account
  2. Select Manage Maps
  3. Select Details
  4. The unlock code is located under the Installed Maps.

  10. Double-Click on the New Text Document. This will open the New Text Document in a window called Notepad
  11. Type the unlock code that is listed in the Manage Maps section of your myGarmin account in all upper-case letters with no spaces
  12. Select File
  13. Select Save As
  14. Change the Save As Type to All Files
  15. Type gmapprom.unl in all lower-case letters for the File name
  16. Select Save
  17. Close the Notepad window
  18. Delete the New Text Document file
  19. Disconnect the GPS device from your computer
Creating an unlock code file for Mac:
  1. Open the TextEdit application located in the Applications folder on the Mac HD
  2. Click Format
  3. Select Make Plain Text
  4. Type in the unlock code that you retrieved from your mygarmin account. The unlock code should be in all capital letters and with no dashes.
  5. Click Save As and name the file as gmapprom.unl (Note: Be sure to uncheck the box If no extension is provided, use .txt)
  6. Copy the gmapprom.unl file to the GARMIN folder on your device. (Note: Save the file directly to the Garmin mass-storage device if connected)

My GPS keeps saying cant unlock maps after i already loaded maps on it


The Garmin Maps require a map unlock code in order for the GPS to be able to open/access it. Since the maps are copyright protected by Garmin you should of recieved the unlock code from Garmin when you purchased the new map update.

Unable to unlock new maps


Where did you download the Australian maps from? If from Garmin, contact Garmin for the unlock code. Maps have to be unlocked to a specific unit.

If you downloaded the maps from the internet, you will still need to contact Garmin for an unlock code.

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?
