Step 4:  Update Software Installation

NOTE: Because of the time it takes to perform these updates, SOA recommends connecting the Midtronics GR8 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode

feature when performing these updates. Once the GR8 is connected to the vehicle, as long as the battery is fully charged, it takes less than 3 minutes to boot-up the charger, select the Power Supply Mode, and have the vehicle’s battery voltage stabilized and ready for updating.

VERY IMPORTANT: This information is applicable to the Midtronics GR8 Diagnostic Battery

Charger ONLY. It does not apply to any other brand / type of “generic” battery charger whatsoever. ONLY the GR8 and its Power Supply Mode feature has been tested and approved by Subaru of

America, Inc. (SOA). If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8 before proceeding to update the audio unit while using the Power Supply Mode.

Once the GR8 has been connected and Power Supply Mode initiated, insert the Drive “1” into the USB port and follow the steps below to install the Update File #1.

Before proceeding further perform Step 1 (Version Check Procedure) again to confirm the updated software installation “from Drive 1” was successful.  When the update is successful, the software version (NOR) NU9011 for Legacy and Outback, NU9016 for Impreza and XV Crosstrek and NU9203 for WRX and the CAN version 14.0012 (Legacy and Outback only) will be displayed.  If OK, proceed with installation of the Drive “2” update (repeat Step 4, Update Software Installation).  If the updated versions are not displayed, Step 4 using Drive “1” must be repeated.

NOTE: If the CAN version displayed after the Drive “1” update is B2.0105, turn the ignition OFF, wait at least 1 minute, turn the ignition back ON and perform Step 1 (Version Check Procedure) again to confirm 14.002 is displayed.

Once the software and CAN version updates are confirmed, insert Drive “2” to install Update File #2 and repeat Step 4.

 

Step 5: Version Check Procedure

As mentioned earlier on page 6, once both update software installations are complete, the Version Check procedure must be performed again to confirm all of the updates have been installed successfully.

  • Switch the unit into “Diagnosis Mode” by pressing and holding the HOME button while pressing the “AUDIO/TUNE” button 5 (five) times.

Press “AUDIO/TUNE” button 5 times

  • Press “Service Information”

Press “Version Information”

  • Press “Service Information”

  • Press “Memory Initialization”

Press and HOLD the “OK” button until the screen shown below is displayed (5 to 10 seconds)

  • Press and HOLD the “OK” button until the screen shown below is displayed (5 to 10 seconds).

This screen will be displayed for about 1 minute while the unit restarts

This screen will be displayed for about 1 minute while the unit restarts.  After restart, the Loading screen and its status bar will be displayed.  After the status bar completes, the Main Menu screen will be displayed.  To complete the updating procedure, you must go through the series of Initial Setup screens, reset the radio station presets and re-pair any mobile devices (where applicable). NOTE:  After confirming the updates are complete, remove the labels and re-format both flash drives to clear any remaining files so they are ready for use the next time.  This reduces the chances of inadvertently combining files the next time the drives are used.  It also ensures that every repair receives the very latest software as these files will be updated from time to time whenever a newer version is released.
