Your vehicle's NAVTEQ navigation system serves as a guide on unfamiliar city streets and highways. Roads change frequently, so NAVTEQ recommends that you update your navigation system maps every year. NAVTEQ sells map updates on DVDs or SD cards. If you bought an update on an SD card, the card only allows you to use the maps for about 600 miles before you need to enter an activation code to unlock the maps on the card for continued use.
Power on the NAVTEQ GPS and press the "Menu" button. Scroll to and select "Configuration." Select "SD Card Management" and "System Serial Number." Write down the 11-digit system serial number.
