2. Press and hold the MAP/GUIDE, MENU, and CANCEL buttons for 3 seconds, or connect the SCS service connector to the navigation service check connector located by the front passenger's kick panel (see FORCED STARTING OF THE AUDIO-NAVIGATION UNIT  ).
3. When the Select Diagnosis Items menu is displayed, select Detail Information & Setting.
