Mic Level

This diagnostic screen allows you to independently test the microphone and the navigation TALK and navigation BACK buttons. They are used to activate the voice control system. The microphone is located near the map light in the ceiling. The microphone 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 navigation TALK button on the steering wheel, wait unit 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 Mic Level indicator on the screen does not briefly turn green, then check the wiring from the navigation TALK button to the audio-navigation unit. If there is no Mic Level movement when you speak, or if all the bars are filled without speaking, then you should check the wires running from the microphone to the control unit for opens or shorts. If the wires are OK, substitute a known good microphone, and recheck.
• If all the bars are filled without speaking or with very little background noise, disconnect the microphone for 1 hour, then reconnect it, and recheck. If the symptom is resolved, the microphone had a glitch and is now reset.
• If the mic level bar is full or almost full without you speaking or other back ground noise, replace the microphone and recheck.
• Press the navigation BACK button on the steering wheel. The Cancel indicator on the screen should momentarily turn green. If it does not briefly turn green, check the wiring from the steering wheel navigation BACK button to the audio-navigation unit.

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".
