Voice control does not work/respond

Diagnostic Test: Mic Level

NOTE:

- Check the vehicle battery condition first Testing and Inspection.
- Check the connectors for poor connections or loose terminals.
- Make sure that the correct navigation DVD color and version are installed.
- Check any official Honda service web site for more service information about the navigation system.
- Before troubleshooting, make sure you have the anti-theft codes for the audio system and the navigation system.
- After troubleshooting, enter the anti-theft code for the audio system and 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 moonroof.
- 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 navigation 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 or high pitched, the system may misunderstand your command.
- Compare the system operation with a known-good vehicle. Have more than one person test the system operation. If the known-good vehicle performs the same, it is a characteristic of the system.
