Garmin GPS devices are manufactured with the Garmin Lock application, which secures your device by prompting you for a four-digit personal identification number each time the GPS unit is turned on. The PIN is created when you turn on Garmin Lock. In addition, you can set up a secure location as a method for unlocking the Garmin Lock. After creating your secure location, the Garmin GPS unit unlocks the device when the unit is at your location. You may decide at a later time to update the PIN and security location. You can reset both security features through the Garmin menu interface.
