Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Mic Level
This diagnostic allows you to independently test the microphone and the navigation TALK and navigation 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 until you hear a beep, and in a normal voice say "testing". The TALK indicator on the screen should momentarily turn green, and the text Now Recording... should appear in yellow. If the talk indicator shown on the screen does not briefly 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 HFL-navigation microphone (see VOICE CONTROL SWITCH REPLACEMENT - ('10 MODEL)Β ).
- Press the navigation BACK button on the steering wheel. This should cause the Cancel indicator on the screen to momentarily turn green. If it does not briefly turn green, check the wiring from the steering wheel navigation BACK button to the audio-navigation unit.
