MATERIALS REQUIRED:

2 empty 2GB, USB 2.0 storage devices (flash drives) will be needed to perform these updates. The devices should be dedicated to storing and transferring these updating files only. They also need to be no more than 4GB in size and contain a FAT32 file format before downloading update files onto them.

 

SERVICE PROCEDURE / INFORMATION:

IMPORTANT REMINDER:  Read through and understand this procedure COMPLETELY before proceeding further.

Step 1: Version Check Procedure

Before proceeding with any updates, the currently installed software version must be determined.  If the latest software version (or later) is already installed, no updates are necessary.  The Version ID numbers for this procedure are found in the Version Check List table shown below.  If the Version ID

numbers identified during the Version Check procedure are prior to (or lower than) those shown on the table, proceed with the remainder of the software update beginning with Step 3.

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

• Press “Service Information”

• Press “Version Information”

• Press “Push” next to AVN

• Verify the current versions according to the “Version Check List” table shown below on page 6. Use the down arrow to scroll to the bottom of the list for complete verification.

• If the software version is current (NU9011 for Legacy/ Outback NU9106 or higher for Impreza/ Crosstrek or NU9203 for WRX), press and HOLD the HOME button to exit the Diagnostic Mode to complete the procedure as no updates are necessary. If no updates are necessary then continue your diagnosis of the customer concern.  If the Version ID numbers are prior to (lower than) those shown on the table below, proceed with Step 2, preparing the USB memory (Flash Drives) on page 7 then Step 3, the software update procedure on page 10.

NOTE: If you determine the updates are necessary, the Version Check procedure will need to be performed again after the update installation to confirm the procedure was successful (Step 5, pg. 17).

After performing the Version Check procedure, if updates are determined to be necessary, you will need the 2 USB flash drives referenced above to download the Update Files onto.  All the F10 update files are accessible for downloading from Subarunet under:

Service>>Forms / Downloads>>Downloads for Audio/Navi page then clicking on the following hyperlink:

Click Here to Access the Downloads for Audio/Navigation Information on Subarunet

The Subarunet page shown above will display and contains links to the update files 1 & 2 for each model head unit.

NOTE: Do not download any files at this point. The file download procedures are supplied later in this bulletin. The flash drives must be formatted before the Update Files can be downloaded onto them.  Proceed to Step 2 below for the flash drive formatting procedure.

 

Step 2:  Prepare the USB Memory (flash drive)

VERY IMPORTANT:  Before attempting to download any data files, confirm the PC and flash drives you are using are not infected with any virus.  The flash drives will need to be formatted for FAT32 following the steps below.

 

USB Flash Drive Formatting Procedure:

• Install a flash drive into an available USB port on your PC.
• Click Start (this is located in the lower left corner of the desktop screen) then, in the Search Search
  programs and files box, type “explorer”.

NOTE: On SDS Notebook you may also press the My Documents button on the GUI Home Screen.

• As you type the word “explorer”, search results will start to appear. In the results, click on the “Windows Explorer” option under the Programs section.

• In the next window, choose the Computer section on the left. Locate “Removable Disk”

NOTE: Always confirm the device you are formatting is the USB Flash Drive.  This drive may have various names assigned to it by the manufacturer of the device and may not reflect the drive name given in this example.

• Right click the picture for “Removable Disk” then select “Format”.

• When the “Format” dialog box appears, make sure that the option labeled “File System” is set to FAT32 and the Quick Format box is checked as well. Then, click the “Start” button.

• Click “OK” when the following window appears.

• The drive will start formatting and display this window when it is finished. Click “OK” to complete the process.

• Repeat the procedure above for the second flash drive.

 

Step 3:  File Download Procedure:

Now that the 2 flash drives have been formatted, the two Update Files must be downloaded, one to each flash drive as shown in the table below.  Label the flash drives L/O1 and L/O2 for Legacy / Outback,  I/X1 and I/X2 for Impreza / XV Crosstrek and W/1 and W/2 for WRX.  Download the Update Files to your PC from the Subarunet links.  The updates must be installed in order, drive “1” first followed by drive “2”.  NOTE:  Each downloaded Update File may contain 1 to 3 individual files.

The screenshots below will take you through the steps required to get the selected Update Files onto your flash drives and ready to use. Update File sizes are quite large and depending on the speed capabilities of the computer you are using, may take some time to complete the download.

PLEASE BE PATIENT!

Once the download is complete, you will need to locate the Update File, unzip it then save the unzipped version to your USB flash drive (Update File #1 onto drive “1”, Update File #2 onto drive “2”).  NOTE:  If you have not already done so, follow the procedure (Step 2 starting on page 7) for re-formatting (removing any existing files) your flash drive.  Plug the “clean” flash drive into your computer.

• Go to your Windows Start screen, select “Computer” (or click on My Documents if you are using the SDS Toughbook) then click on “Downloads”.

• Once your list of downloaded files opens, locate and click on the downloaded Update File (in this example, “OU9103_USB…”) you are looking for. TIP: If you click on Date Modified you can sort the downloaded files by the date they were added which will bring the newest file to the top.

• Double clicking the Update File will bring up a dialogue box with a security warning. Click on “Run” to continue.

• As shown below, click on “Removable Disk” which is your USB flash drive where you want the unzipped _file(s) to be saved. Click “OK” then click on “Unzip”.

• The Update File will unzip and be saved to your flash drive.

• Confirm the Update File (and flash drive) is ready to use by going back to Start > Computer (or My Documents on the SDS Toughbook) and double clicking on “Removable Disk” to display the drive’s contents as shown in the examples below.  Some Update Files will consist of just 1 item but others may list 3.  All of the files will have a “.kwi” extension at the end of their file name.  If OK, proceed with Step 4: Update Software Installation below.

REMINDER: There can only be ONE Update File stored on each flash drive or the update procedure will not work. If you see more than one Update File stored, start over by re-formatting the flash drive again and reloading the Update File you are trying to install.

 

IMPORTANT NOTES:

• Do not change the Update File names after downloading them.
• Do not save any other version Update Files onto the flash drives.

MODEL	FACE PLATE ID NUMBER	1ST UPDATE SOFTWARE FILE NAME	2ND UPDATE SOFTWARE FILE NAME
Legacy / Outback	FB664US	NU9011_USB_1st.exe	NU9011_USB_2nd.exe
	FB644US
Impreza / XV Crosstrek	FM634US	NU9106_USB_1st.exe	NU9106_USB_2nd.exe
WRX	FV631US	NU9203_USB_1st.exe	NU9203_USB_2nd.exe

 

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.

NOTE: Where applicable, record any radio station presets as they will be lost along with any mobile device pairing during this procedure.

 

Version Update Procedure

• Turn the ignition / key (ACC) “ON”.

• Press the “AUDIO/TUNE” button.

The Select Audio Source screen will appear.

Install the flash drive into the vehicle’s USB port.  After the flash drive is recognized, the USB icon will illuminate.

• Once the USB icon is illuminated, switch the unit into “Diagnosis Mode” by pressing and holding the HOME button while pressing the “AUDIO/TUNE” button 5 (five) times.

• Press “Service Information”

• Press “Program Update” then follow the sequence shown in the screen shots below

Wait for “OK” to activate (turn black)	Press “OK”	Press “SELECT”

 

NOTE:  The “OK” button will not activate (turn black) if the wrong Update File(s) are on the flash drive.  Re-format the flash drive and reload the proper Update Files starting from the beginning of  Step 2.

Press “OK”	Once the updating starts, the status bar may need to complete more than once and could take up to about 15 minutes.	Turn off ACC

If the progress bar stops, please wait 15 minutes. If the progress bar does not change even if after 15 minutes, turn ACC OFF and back ON again then, restart the update procedure from Step 4.

 

IMPORTANT:  Do not turn the ACC (ignition / key) off or disconnect the flash drive from the USB port during updating.

• Once the update completes successfully, turn the ACC off, WAIT 30 SECONDS then turn it back on again.

• After the unit boots back up, the “Updating software” screen and its status bar will be displayed. This update may take up to 5 minutes to complete.

When the Software Update completes, the unit will restart automatically.  Once the STARLINK opening screen is displayed, remove the flash drive from the USB port and turn the ACC off. 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 “Service Information”

• Press “Service Information”

• Press “Push” next to AVN

 

• Verify the current versions according to the “Version Check List” table shown on page 6. Use the down arrow to scroll to the bottom of the list for complete verification.

 

Step 6: Memory Clear Procedure

After confirming both software updates have been installed successfully, the Memory Clear procedure must be performed to complete the update procedure.  After pressing “Back”, the following screen will be displayed:

NOTE: All presets will likely be lost and will need to reset after performing this procedure.

 

• Press “Memory Initialization”

• 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.  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.
