Materials Required:
An empty, USB 2.0 or 3.0 storage device (flash drive) will be needed to perform the update
procedure. The device should be dedicated to storing and transferring these updating files only. It
must be a minimum of 16GB or more in size and contain a NTFS file format before downloading the
update files onto it.
IMPORTANT NOTES:
• NEVER change the update file names after downloading them.
• NEVER save any other files on the same flash drive.
There are various types of USB flash drive available from many suppliers. If the head unit does NOT
recognize the USB drive during the reprogramming process, due to controller IC type of USB drive
or compatibility with the head unit, clear the file and re-format the flash drive for “FAT32” as outlined
below in Step 2 instead of “NTFS”. If a recognition problem persists, use USB flash drive from
another manufacturer.
Recommended Flash Drives:
• Kingston®: Data Traveler G3, G4, SE9 or the Hyper-X Series
• SanDisk®: Cruzer Series, Ultra Flair
• Transcend®: JetFlash 300, 600 or 790
• Verbatim®: Store ‘n’ Go

• 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 – 2019-20 Impreza_Crosstrek_Crosstrek Hybrid_BRZ_Forester_Ascent_WRX & 2019 Leg…
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: 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.

Continued…
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.)
• CRITICAL STEP: After the reboot process completes, press the HOME button to
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”.
Bulletin Number: 15-236-18R; Revised: 12/08/23 Page 11 of 24

Rel_UK.23.16.70
• Press (Home) to return to the Home screen and shut the engine OFF. Open and close the
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 return
to the Home screen and shut the ignition OFF to complete the procedure.
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.

temporarily. In case the customer terminates the MOTA when in this condition, the map stays
blank (white). See NOTE 1 below.
10) Hands Free conversation volume not loud enough compared to the audio volume (unfavorable
balance). See NOTE 2 below.
11) Added function for SXM Weather Alert setup. See NOTE 3 below.
NOTE 1: The MOTA operation is performed in two steps, i.e., Downloading (download the map
data to the H/U via Wi-Fi) and Overwriting (replace the map data to new one inside the H/U.)
Before updating the software to Ver. 6, the map screen turns blank (white) during the Downloading
process until it is completed. If the customer stops (by turning off the H/U,) during the Downloading
process, the map display will stay in blank condition. The MOTA operation can be restarted even in

Downloading. However, the map still turns to blank (white) during the Overwriting process, which is
a normal operating characteristic.
NOTE 2: To meet with customer expectations, Ver. 6 software will increase the Hands-Free
conversation volume by 6dB against the base audio volume. Customers will now be able to hear
Hands Free conversation volume which used to be at audio volume level 30 at level 22 after installing
this update. If the customer prefers the original Hands-Free conversation volume setting, it can
be manually adjusted by following: Home >> Settings >> Sound Tab >> Phone Volume >> then
lowering the volume 6 – 8 steps.
The base audio volume setting chosen at the Factory Data Reset is at level 22 compared to the
previous setting, which is level 30. (This means customers will no longer have to adjust the base
audio volume to get comfortable Hands-Free conversation volume.)
NOTE 3: Added function for SXM Weather Alert is only applicable to HIGH grade head unit.
Conditions Addressed By Update #3:
1) Steering wheel satellite switches (other than volume control) and head unit hard buttons (other

numbers.
NOTE 1: The MOTA operation is performed in two steps, i.e., Downloading (download the map data to the H/U via Wi-Fi) and
Overwriting (replace the map data to new one inside the H/U.) Before updating the software to Ver. 6, the map screen turns blank (white)
during the Downloading process until it is completed. If the customer stops (by turning off the H/U,) during the Downloading process, the
map display will stay in blank condition. The MOTA operation can be restarted even in this condition. After the Ver. 6 software is installed,
the map does not turn to blank (white) during Downloading. However, the map still turns to blank (white) during the Overwriting process,
which is a normal operating characteristic.
NOTE 2: To meet with customer expectations, Ver. 6 software will increase the Hands-Free conversation volume by 6dB against the
base audio volume. Customers will now be able to hear Hands Free conversation volume which used to be at audio volume level 30
at level 22 after installing this update. If the customer prefers the original Hands-Free conversation volume setting, it can be manually
adjusted by following: Home >> Settings >> Sound Tab >> Phone Volume >> then lowering the volume 6 – 8 steps.
The base audio volume setting chosen at the Factory Data Reset is at level 22 compared to the previous setting, which is level 30. (This
means customers will no longer have to adjust the base audio volume to get
comfortable Hands-Free conversation volume.)
NOTE 3: Added function for SXM Weather Alert is only applicable to HIGH grade head unit.
