Mic Level
This diagnosis allows you to independently test the microphone and the TALK and BACK buttons. The TALK button is used to activate the voice control system. The microphone is located near the map light in the roof console. The microphones 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 TALK, button on the steering wheel, wait until you hear a beep, and in a normal voice say "testing". The TALK icon (A) on the screen should momentarily turn green, and the text Now Recording!! should appear. If the TALK icon does not turn green, check the wiring from the voice control switch to the HandsFreeLink control unit, If there is no Mic Level (B) movement when you speak, then you should check the wiring from the microphone to the audio-navigation unit (via the HandsFreeLink control unit). If the wires are OK, the microphone must be faulty; replace the microphone .
- Press the BACK button on the steering wheel. The BACK icon (C) on the screen should momentarily turn green. If it does not briefly turn green, check the wiring from the steering wheel BACK button to the HandsFreeLink control unit.
NOTE:
The mic level should reach the 6th bar.
