WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Check the vehicle battery condition first (see BATTERY TEST ).
- If you press and hold the VOLUME/POWER knob for at least 2 seconds, the audio-navigation unit automatically checks the VIN and exits the anti-theft mode. If the unit does not exit the anti-theft mode, go to Audio unit does not exit anti-theft mode troubleshooting (see AUDIO UNIT DOES NOT EXIT ANTI-THEFT MODE (WITH NAVIGATION) ).
- Check for and resolve all CAN DTCs before troubleshooting the navigation system.
- Verify that the correct navigation unit is installed for this model. Go into the System Diagnostic Mode (see SYSTEM DIAGNOSTIC MODE ), and use Version (see VERSION ).
- Check the connectors for poor connections or loose terminals.
- Check any official Honda service website for more service information about the navigation system.
- Turn the ignition switch to ON (II). Make sure the anti-theft mode is released.
- Turn on the audio system, and check for sound in each mode (AM/FM and CD).
Is the sound normal?

NO -Go to Sound Quality Diagnosis (see SOUND QUALITY DIAGNOSIS ) or No sound is heard from the speaker(s) (display is normal) troubleshooting (see NO SOUND IS HEARD FROM THE SPEAKER(S) (DISPLAY IS NORMAL) (WITH NAVIGATION) ).
- Check for the hard error code (see How to Check Error History (Navigation DTCs) ).
Are there any navigation DTCs indicated?
YES -Troubleshoot the indicated navigation DTC(s).
NO -Substitute a known-good audio-navigation unit (including the HDD) (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ), and recheck. If the symptom/indication goes away, replace the original audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
