Mic Level
WARNING: This page is about a different car, the 2008 Acura TSX, 2007 Acura TSX, and 2006 Acura TSX. 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 TALK/BACK buttons. They are used to activate the voice control system. The microphone is located near the map light in the ceiling. It is directional, and works best if the voice is 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. In addition, the Mic Level indicator should move at least to the 6th bar. If the talk indicator on the screen does not briefly turn green, then check the wiring from the TALK button to the navigation unit. If there is no "Mic Level" movement when you speak, then you should check the wire running from the microphone to the control unit.
- Press the BACK button on the steering wheel. The Cancel indicator should turn green momentarily. If it does not briefly change to green, then check the wiring from the steering wheel BACK button to the navigation unit.
