Check The DVD-ROM

An opening screen is displayed, then it switches to the map screen after a while.

When a screen other than the opening screen is displayed, press the «AP» key. Standard value: The map screen should be displayed.

OK: Normal

NG: If the map screen is not displayed, check whether the DVD-ROM is set in the navigation system, 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.
