The Sony NV-U73 (also called the NV-U73T), is a 4.3-inch portable GPS navigation system. The NV-U73 features include not only a touch display and various maps for navigation, but also a password-protected unit lock that keeps an unauthorized user from accessing the system. Unlocking the NV-U73 isn't difficult. Sony has designed the unit's Password Lock screen with several settings including lock deactivation. You simply need to access the screen, make the correct selections and enter your 4-digit security password.
