Mic Level

This diagnostic allows you to independently test the microphone and the navigation TALK and BACK buttons. They are used to activate the voice control system. The microphone is located near the map light in the roof console. The microphone can now isolate the driver's voice even when there is noise or other conversations in the vehicle. To properly check the microphones, make sure you are sitting in the driver's seat.

• Press the navigation TALK button on the steering wheel, wait unit you hear a beep, and in a normal voice say "testing." The TALK indicator on the screen should turn green, and the text Now Recording... should appear in yellow. If the talk indicator shown on the screen does not turn green, check the wiring from the steering wheel navigation TALK button to the audio-navigation unit. If there is no Mic Level movement when you speak, then you should check the wires running from the microphone in the roof console to the audio-navigation unit. If the wires are OK, the microphone must be faulty; replace the microphone located in individual map light (see VOICE CONTROL SWITCH TEST/REPLACEMENT  ).
• Press the navigation BACK button on the steering wheel. This should cause the BACK indicator on the screen to turn green. If it does not turn green, check the wiring from the steering wheel navigation BACK button to the audio-navigation unit.
