If you can send it in to Garmin to have it unlocked, then there must be a "master" code. Since the USB port is dead until the unit is unlocked, Garmin must have to either enter in some special code or reset the unit in some special way.

You don't need to enter a PIN if you are at your security location (the location you set when you set the PIN). If you don't know the PIN or the security location, you'll have to send it in to get it unlocked.

SOURCE: forget pin code

The only way to unlock a PIN locked Garmin is to enter the correct PIN number (1111 won't work unless it is the correct PIN #), or take the unit to where the PIN was initially set. Why not ask your friend the PIN #? Your only other option is to send the unit to Garmin. There is no "master" PIN code.

SOURCE: master pin reset

There is no master PIN reset. You have to either send the unit back to Garmin or go to the secure location where the PIN was set to unlock the unit or enter the correct PIN.

Forgot my pin

Wedll if this is not a stolen GPS Then the matter is simple. Take it back to the exact coordinates that you set the pin in. Then you will be able to access the pin setup and reset it to a new password. Your only other choice is to send it to Garmin, but if it has been listed as stolen, then expect the cops! No one forgets their pin or fails to remember the instructions for setting and recovering their pin.

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. “
