you will have to ask the previous owner for the lock code. if he doesn't know it, get you money back from him. the only way to unlock a garmin is to know which location the code was first programmed in or by sending it back to garmin with proof of purchase. this is an anti-theft feature.
Unfortunately, even if you perform master reset on Garmin GPS unit, it does not reset Garmin Lock security feature, which password-protect most Garmin electronic devices to deter theft. If you forget the PIN or password unlock code to unlock the Garmin unit, the best solution is to bring it to Garmin to get unlocked. “Secure Location” does not unlock a locked Garmin unit either as it’s only a temporary fix as when it’s turn on outside the security location, the device is locked again."
So unfortunately, there is only one option: You have to send your nüvi into the Garmin, who can unlock it. Remember original receipt.
Pull the face off, press reset button under it,
then update it at Garmin's Web-updater website.
If it wiil not reset like this
Press the lower right corner of the screen, while turning on, keep pressing until the message
" do you want to remove all data " appears, click yes
Then re-register it at Garmin, then re-update it at Garmin
Have you tried putting the unlock code in the main directory? To do this open up notepad or some similar text program and copy the code from the yellow sheet onto the note pad and save it as GMAPPROM.UNL. Then open "My Computer" and locate the Garmin removable device. Open the "Garmin" folder and copy that file to it. Safely remove it from your system and turn it on.
Carefully remove face plate bezel. There is a reset button on the right side of the face. Press the button and then restart normally. It's in the owners manual if haven't lost yours like I did. The manual is on Garmins website.
