Unit Check: Display

This performs additional checks on the communication bus between the navigation unit and the navigation display unit. In addition, the internal electronics and touch screen functionality are confirmed.

• When the connection is NG, first check for loose terminals at the navigation unit, the navigation display unit and the audio unit connections. Next, check for an open or short in the communication line between the navigation unit, the navigation display unit and the audio unit. If you find the line has an open or short, replace the affected shielded harness.
• If the ROM or RAM is NG, replace the navigation display unit.
• The version represents the software version in the display.
