Voice Control Does Not Work/Respond

Voice control does not work/respond

NOTE:
- Always make sure that the correct DVD color and version are installed.
- Check on-line for service bulletins or other service information for the navigation system.
- Before assuming that a voice complaint is hardware related, ensure that the voice control system is being operated correctly.
- Make sure you are on the correct screen when trying to issue a voice command. For instance, the command "Find the nearest Italian Restaurant" only works on Map screen. (See the Navigation System manual for a complete list of allowed voice commands for the information being displayed).
- Close the windows and sunroof.
- Set the fan speed to low (1 or 2).
- Adjust the air flow from the air conditioning vents so that they do not blow against the microphone on the ceiling.
- Pause after pressing the TALK button then give a voice command clearly in a natural speaking voice. If the system cannot recognize your command, speak louder.
- If the microphone picks up voices other than yours, the system may not interpret your voice commands correctly.
- If you speak a command with something in your mouth, or your voice is too husky, the system may misunderstand your command.
- Always check the connectors for poor connections or loose terminals.
- Check for a loose roof console microphone; if it's loose, tighten it.
- Before troubleshooting, write down the audio presets, and get the audio and navigation system anti-theft codes.
- After troubleshooting, enter the anti-theft codes for the audio system and the navigation system, and the audio presets.
- Determine if the problem only happens to one person, or everyone who uses the system.
- If the system only has a problem with one person's voice, this should be considered a system limitation.

1. Go into the Diagnostic Menu, and use the "Mic Level" test the under Functional Setup to check the operation of the TALK and BACK buttons.

Are the TALK and BACK buttons operational?

YES - Go to step 2.

NO - Check for an open or short to ground on navigation unit connector B (14P) No. 10 terminal.

2. Use the "Mic Level" diagnostic under Functional Set-up to check the operation of the microphone.

Is the microphone operational?

YES - Check the operation of the voice control system (see the Navigation System Manual).

NO - Check for a loose front map light (microphone) assembly. If OK, check for an open or short to ground on navigation unit connector B (14P) No. 6 and No. 14 terminals.
