Mic Level

This diagnostic 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 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 TALK button to the HandsFreeLink control 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 HandsFreeLink control unit and the audio-navigation unit If the wires are OK, the microphone must be faulty, replace the microphone located in roof console (see HFL-NAVIGATION MICROPHONE REMOVAL/INSTALLATION )
• Press the 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 BACK button to the HandsFreeLink control unit
