B: INSPECTION
1. CHECK THE OPERATION OF THE NAVI-
GATION.
Start the engine, and then inspect that the opening
screen is displayed.
Standard value: The opening screen should be dis-
played.
OK: Normal
NG: When not displayed, check the signal line con-
nector and the audio connector. If there are no
problems in the connecting lines or the lines were
repaired, check that the opening screen is dis-
played.
At this point, if the display is not viewable, the unit is

whether the DVD-ROM is set in the navigation sys-
tem, whether the correct side is set, type of the
DVD-ROM, the existence of any scratches, etc. If
there are no problems on the DVD-ROM, the main
body is defective.
3. CHECK EACH CONNECTION
