Factory diagnostic screen ‘‘In Line Diag'' When a navigation control unit is powered up for the first time at the factory, the ‘‘factory diagnosis'' screen (In Line Diag) shows up. Normally the factory performs the steps necessary to verify proper operation and terminate the ‘‘factory diagnostic''. Until the proper confirmation sequence is performed, the screen will show up every time the vehicle is started. Follow the steps below to prevent the screen from showing up in the future: Hold down the buttons (Menu + Map/Guide + Cancel) for about 5 seconds (the ‘‘Select Diagnosis Items'' screen will appear) Hold down the Map/ Guide button for 5−10 seconds (A screen with a ‘‘Complete'' button, will appear) Touch ‘‘Complete'', and then the ‘‘Return'' button (the system may re-boot) Restart the vehicle, and confirm normal operation by completing the ‘‘PDI of the navigation system'' Service Bulletin. |
