NO -
- If there is no sound in all modes, go to step 3.
- If there is no sound in AM/FM mode, go to Poor AM or FM Radio Reception Or Interference (With Navigation) .
- If there is no sound in CD mode, go to Audio Disc Does Not Play .
- If there is no sound in the USB mode, go to USB Input Sound Is Low Or Cannot Be Heard .
- Check for sound in each mode (AM, FM and CD).
Is the sound OK in each mode?
YES - Intermittent failure. The system is OK at this time. Check for loose connections at the audio-navigation unit and speaker(s).
NO - Go to step 4.
- On the steering wheel, check the navigation talk command.
Is the navigation talk command function set?
YES - Cancel the navigation talk command by pressing the navigation BACK button, then recheck the function.
NO - Go to step 5.
- Turn the ignition switch to LOCK (0).
- Check the speaker (s) with no sound for any damage.
Is there any damage?
YES - Replace the speaker (see SPEAKER TEST/REPLACEMENT ), and recheck.
NO - Go to step 7.

- Check the speaker 2P connector for a loose or poor connection.
Reconnect the speaker 2P connector, and recheck the symptom; does it still fail?
YES - Go to step 9.
NO - Intermittent failure. Operation is normal.
- Test the speaker (s) (see
Speaker Test/Replacement ).
Is the speaker OK?
YES - Go to step 10.
