Voice control does not work/respond

NOTE:

Check the vehicle battery condition first (see 12 VOLT 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.
