REPAIR PROCEDURE 2015 MDX
NOTE:
- If the vehicle does not have navigation, do not use this software update. If you do, you may permanently damage the audio unit.
- Apply this software update only to the vehicles listed under AFFECTED VEHICLES; otherwise this software update can permanently damage the unit.
- If you accidentally update the wrong vehicle, contact Tech Line; if the unit must be replaced, your dealership may be debited for the replacement cost.
- Connect a battery charger or a fully charged jumper battery to the vehicle and leave it connected during the entire update procedure to maintain a steady voltage.
- Set the power mode to ON.
- Press the Settings button.
- Select Navi Settings, then press the interface dial (jog knob).
- Scroll down and select System Device Information.
- Check the Database version is VER.ST003.02.00.
- If the version matches, continue to step 4.
- If the version is different, a 2017 or above Navi map update must be performed (this should only be in the rare case when the client did not take advantage of the now expired Client Satisfaction Improvement Campaign). The map database must be completely installed, including the background update, before continuing with this bulletin. If you try to update the ODMD without the correct software version, the ODMD will not work properly.
NOTE: If you are doing the 2017 or later navigation map update, make sure to use the correct WARRANTY CLAIM INFORMATION.
- Set the power mode to OFF, then to ON and wait for the navigation system to boot up. Insert the RED DVD into the CD slot as shown. See TOOL INFORMATION.
NOTE: The power mode must remain ON during the entire update procedure. If the power mode is set to OFF, the engine is started, or the DVD is removed at any time during the update process, the audio-navigation unit will be locked up and you will need to use the RECOVERY PROCEDURE.
- The software update will begin. The screen will show a Reading the Disc message, then both screens will shut off for about 10 seconds and reboot. The message No Data will appear on the screen. Do not eject the disc. The unit is uploading the update and may take up to 1 minute before beginning. The displays should change to a Notification screen loading bar.
NOTE:
- The engine does not need to be running to do this update, even if it says so on the screen.
- If the No Data screen does not change after about a minute, the software may already be updated. Go to step 11 to confirm the software versions.

On the touch screen, the progress bar will stop at 100% after ERATO is updated and remain at 100% throughout all SH and Utility updates. The progress bar will go back to 0% and resume when the BUuCOM update starts.

NOTE:
- You must wait for both screens to appear before setting the power mode to OFF, or you will lock up the unit.

RECOVERY PROCEDURE

- Remove the jumper wire, and reconnect the battery cables – positive cable first, then negative.
- Reattach the battery charger or fully charged jumper battery.
- Set the power mode to ON (do not start the engine).
NOTE: Do not start the engine because starting it interrupts the steady battery power needed to update the audionavigation unit.

- The recovery procedure and software update reload takes 15–30 minutes depending on when the update procedure was interrupted.
