Voice control does not work/respond
NOTE:
- Check the vehicle battery condition first Battery Test.
- Make sure that the latest navigation software is installed.
- 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 Manual for a complete list of allowed voice commands for the information being displayed)
- Close the windows and moonroof
- 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 you speak a command with something in your mouth, or your voice is too husky, or high pitched, the system may misunderstand your command
- Check the connectors for poor connections or loose terminals.
- Check for a loose roof console microphone; if it's loose, tighten it.
- 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.
- Check any official Honda service website for more service information about the navigation system.
