Mic Level
WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
This diagnostic allows you to independently test the microphone and the NAVI 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. It is directional, and works best with the voice coming from the drivers seat.
- Press the TALK button on the steering wheel, 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 on the screen does not briefly turn green, then check the wiring from the steering wheel TALK button to the 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 HFL unit and the navigation unit. If the wires are OK, the microphone must be faulty; replace the roof console (see HEADLINER REMOVAL/INSTALLATION ).
- Press the BACK button on the steering wheel. This should cause the BACK indicator on the screen to momentarily turn green. If it does not briefly turn to green, then check the wiring from the steering wheel BACK button to the navigation unit.
