Mic Level

WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

This diagnostic allows you to independently test the microphone, the TALK and 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 yellow. If the Mic Level 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. This should cause the Cancel indicator on the screen to momentarily turn green. If it does not briefly change to green, then check the wiring from the steering wheel BACK button to the navigation unit.
The mic level should reach at least the 6th bar.

NOTE: If the radio is off, and there is movement in the indicator-even without speaking, then ensure that the vents are not blowing on the microphone.
This should resolve voice control complaints such as:

Sometimes the system does not understand my commands.
I have to shout at the navi for a command to be recognized.
The system just says "pardon"
