Voice Control Does Not Work/Respond
Voice control does not work/respondNOTE:
- Make sure that the correct DVD color and version are installed.
- Check any official Honda service website for more service information about the navigation system.
- Check the connector for poor connection or loose terminals.
- Before troubleshooting, make sure you have the navigation system 4-digit anti-theft code, then write down the audio presets.
- After troubleshooting, enter the anti-theft code then enter the audio presets.
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 a Map screen.
(See the Navigation System Manual for a complete list of allowed voice commands for the information being displayed.)
- Close the windows, moonroof, and doors.
- 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.
- Compare the system operation with a known-good vehicle. Have more than one person test the system operation. If the like known-good vehicle performs the same, if is a characteristic of the system.
1. Turn the ignition switch to ON (II).

Is there continuity?
YES - Replace the navigation unit.
NO - Repair open in the wire between navigation unit and voice control switch, or replace the cable reel.
10. Disconnect the cable reel 20P connector and navigation unit connector D (5P).
11. Check for continuity between body ground and navigation unit connector D (5P) terminals No. 4.
Is there continuity?
YES - Repair short to body ground in the wire between navigation unit and voice control switch, or replace the cable reel.
NO - Go to step 12.
12. Check for continuity between navigation unit connector D (5P) terminal No. 4 and cable reel 20P connector terminal No. 8.
Is there continuity?
YES - Go to step 13.
NO - Repair open in the wire between navigation unit and voice control switch, or replace the cable reel.
13. Disconnect navigation unit connector B (22P).
14. Check for continuity between navigation unit connector B (22P) terminal No. 6 and cable reel 20P connector terminal No. 10.
Is there continuity?

16. Turn the ignition switch to LOCK (0).
17. Remove the moonroof switch and disconnect the microphone 3P connector.
18. Disconnect navigation unit connector D (5P).
19. Check for continuity between body ground and navigation unit connector D (5P) terminal No. 2 and No. 5 individually.
Is there continuity?
YES - Repair short to body ground in the wire(s) between navigation unit and microphone.
NO - Go to step 20.
20. Check for continuity between navigation unit connector D (5P) according to the table.
Is there continuity between any of the terminals?
YES - Short in the wire(s) between the navigation unit and microphone. Replace the affected shielded harness.
NO - Go to step 21.
21. Check for continuity between navigation unit connector D (5P) and microphone 3P connector according to the table.
Is there continuity?
YES - Substitute a known-good microphone, then reconnect all of the connectors and recheck. If the symptom/indication goes away, replace the original microphone. If the symptom/indication is still present, replace the navigation unit.
