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, you hear a "bong" sound. The system is in a "Detecting" mode, and is waiting for all items in white to be tested. This includes the navigation voice control (Talk/Back) buttons, and microphone. Press the navigation Talk button on the steering wheel, and in a normal voice, say "testing." The TALK indicator on the screen should turn green, and the voice level indicator should move to at least the 6th bar to pass. Next, press the navigation Back button. The "Cancel" indicator should turn green.
If all of the communication lines connecting the system components, and the navigation Talk/Back buttons/microphone check out OK (all block diagram items green), then the "OK" indicator turn green.
If there is a problem with the system, the faulty system component item turn 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 you cycle the ignition switch. 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 find the problem.
