Summary
The following information addresses reprogramming file availability and a software update installation procedure to provide optimization to the new Harman Gen 3.1 Audio and Navigation head units utilized in the models as listed above. The procedure will involve either downloading the software update files from Subarunet (or using those sent directly from Nuspire) and transferring them onto a flash drive for head unit installation.
After confirmation, move to the car and either start the engine or follow the procedure as
outlined in document GR8-1100 on STIS for use of the GR8’s Power Supply Mode.
HIGH - 19 Impreza - 19 Crosstrek - 19 Legacy-Outback - 19 BRZ - 19 Forester - 19 Ascent...
Copy ONLY the folder named “update” to the USB.
•
Never change the folder name from “update”.
•
Confirm there is only a folder named “update” on the flash drive.
CAUTION: Confirm one final time the head unit you are about to update matches the update file
selected. Attempting to install the incorrect update file will disable the head unit.
STEP 5- Update Installation:
IMPORTANT INFORMATION: Review these points carefully BEFORE proceeding.
• On 2019 Legacy/Outback models equipped with versions Rel_UA.19.01.70 or Rel_UD.19.17.70,
the new software update will only correct satellite switch functionality conditions.
• On any model other than 2019 Legacy/Outback equipped with versions Rel_UA.19.01.70 or Rel_
UD.19.17.70, there will be no improvements if the current software is applied as the software
these vehicles have is already equivalent to the latest update.
• Vehicles equipped with software version Rel_U1.18.38.50, Rel4.18.11.50, Rel_U0.18.30.20,
Rel4.18.20.50, or Rel_U1.18.20.60 will receive the listed improvements when installing this
latest software update.
IMPORTANT: Always record the customer’s radio station presets and navigation favorites (where
applicable) before proceeding further as they will most likely need to be reset once the update and
re-boot procedures are completed. In addition, some customizable system settings may need to be
reset as they may return to the default setting during the update.
•
With the engine idling (or GR8 connected), plug the flash drive into the USB Port.
IMPORTANT NOTE: If the head unit does not recognize the USB flash drive during the

reprogramming process, this may be due to an incompatible Controller IC in the USB flash drive or
it is otherwise incompatible with the head unit. If this occurs, delete all files from the flash drive and
re-format it to “FAT32”, instead of “NTFS” and reload the appropriate “update” folder to the USB
flash drive. If the USB flash drive is still not recognized, please discontinue the use of that drive and
instead use a USB flash drive from a different manufacturer.
•
After the unit “authenticates” the USB flash drive, press “Next” and after the second screen is
displayed, press “Next” again.
NOTE: If an attempt is made to install the wrong “grade” file into the wrong grade head unit
(EXAMPLE: “Base” update file into a “Base Plus or Mid” or “High” head unit), the USB
Authentication error screen below will be displayed:
•
The current and available software version information will be displayed. The Available
Version I.D should be Rel.19.22.70.
•
After confirming the Available Version, press “Install Now” to start the reprogramming
process. The screen will go blank (black) for a brief period after installation begins.
•
Each of the updates (Base, Mid and High) should take less than 10 minutes to install.

IMPORTANT NOTES:
• Do not leave the vehicle once the update begins as ignoring pop-up requests may lead to
battery discharge.
•
Do not touch any of the buttons on the head unit while the updating process is taking place.
•
If during the updating an error screen is displayed asking “Do you want to Retry”, press
“Retry” to restart the update.
•
Once the updating process is complete, the head unit will perform a “soft” reboot.
(NOTE: several “hard” reboots are required to fully install the update. This procedure is
covered in Step 6 below.)
•
button to
CRITICAL STEP: After the reboot process completes, press the HOME
return to the HOME screen. (NOTE: If the “install message” is displayed asking if you
want to start the update process again, press “Cancel”, press the HOME button again and
return to the HOME screen.)
STEP 6 - Turn the ignition OFF, open and close the driver’s door then remove the flash drive from
the USB port. If an error screen is displayed asking “Do you want to Retry”, press “Cancel”.
IMPORTANT: Wait AT LEAST 3 MINUTES before proceeding to Step 7.
STEP 7- Verify the newly-installed Software Version ID using the following steps:
•
Turn the ignition back ON. Confirm the “SUBARU
STARLINK” screen is displayed. If
“SUBARU STARLINK” screen is NOT displayed on the first screen, system did not fully
enter “sleep mode” and reboot properly. Perform Step 6 again and wait AT LEAST 3
MINUTES before proceeding.
•
In some cases, the radio presets may not appear initially.
•
From the HOME screen, touch “Settings”.
•
From the Settings > General screen, scroll down to and then touch “System Information”.

driver’s door.
STEP 8- CRITICAL: Operation Check and Full Re-Boot Procedure:
1) Turn the ignition back ON (ACC) and confirm normal system operation.
•
2) Confirm the Home screen is displayed.
3) Turn the ignition OFF, open and close the driver’s door then WAIT AT LEAST 3
MINUTES to confirm the unit “times out” or “goes to sleep”.
4) Perform 1), 2) and 3) above again twice. If normal operation is confirmed, press
to the Home screen and shut the ignition OFF to complete the procedure.
to return
IMPORTANT: If during this procedure, the screen goes blank (black) and the STARLINK
screen does not appear, the head unit must be replaced. THIS SHOULD BE A VERY RARE
OCCURRENCE. Contact SOA Techline should this condition occur.
STEP 9- If lost during the update process, reset the customer’s radio station presets, navigation
favorites (where applicable) and if necessary, reset the clock to complete the procedure.
