Navi System Link

- This diagnostic tests the cables connecting the navigation components. Ensure that the ignition switch is in the ON (II) position. When the diagnostic begins, a ‘‘bong‘‘ sound is heard. The system is in a ‘‘Detecting'' mode, and is waiting for all items in white to be tested. This includes the voice control (Talk/Back) buttons, and microphone. Press the TALK button on the steering wheel, and in a normal voice, say ‘‘testing‘‘. The Talk indicator on the screen should become green, and the voice level indicator should move to at least the 6th bar to pass. Next, press the Back button. This should cause the ‘‘Cancel‘‘ indicator to go green.
- If all of the communication lines connecting the system components, and the Talk/Back switch buttons/microphone check out OK (all block diagram items green), then the ‘‘OK'' indicator will become green.
- If there is a problem with the system, the faulty system component item will change to red, and the screen will show ‘‘NG'' in red. Use the troubleshooting index, and other diagnostic screens to help locate the problem.
- The indication on the screen may not change until the ignition switch is cycled. After repairing the affected cable or system, repeat this diagnostic.
  NOTE: Green boxes and green ‘‘OK'' indicate that the communications lines (cables) are intact. This diagnostic does not necessarily imply that the individual components are functioning properly. For instance, the GPS antenna wire may be crushed, but still show as ‘‘green'' . A road test, or other diagnostic may be necessary to fully test each component.

NOTE: The mic level indicator must reach the 6th bar or greater to pass the test.
