SUBJECT:
Reprogramming File Availability for Additional
Optimization of Harman Gen 3 Audio and Navigation
Head Units
INTRODUCTION:
The following information addresses reprogramming file availability and a software update
installation procedure to provide optimization to the Harman Gen 3 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. It is VERY IMPORTANT to read and understand this
information completely to understand all changes from prior releases before proceeding.
IMPORTANT NOTES:
•
If a vehicle presents with a current blank or black screen condition, request an exchange unit.
•
Be sure to locate and re-format any existing USB drives used for updating Harman audio units in
order to fully clear them before adding these new files to them.
CAUTION: NEVER attempt to install this software on any
2019 MY vehicles as they are equipped with Gen 3.1 Audio/
Navigation systems. This update is ONLY for models equipped
with Gen 3.0 Audio/ Navigation systems. Should an attempt be
made to install any of these files into a Gen 3.1 head unit, the
authentication error screen to the right will be displayed.
* NOTE: On BRZ models, this update applicable to HIGH / Navigation - equipped head units only.
•
If the navigation maps have been recently updated, the newest software may have already been
installed at the same time. This may eliminate the need to attempt any further update of the
software. ALWAYS check the head unit’s software version prior to attempting any new software
installation.
CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles,
or to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

PRODUCTION CHANGE INFORMATION:
These latest updates (June 2019) apply to the models listed above equipped with Harman Gen 3.0
Audio and Navigation head units only. They include all previous enhancements implemented in all
prior software updates INCLUDING the previously released WTN-74R updates. Therefore, if
WTN-74R is still open, these latest updates will continue to satisfy the campaign. See the
WARRANTY / CLAIM INFORMATION section at the end of this bulletin for further instructions.
The latest software version (including all available updates) was incorporated into production per the

Materials Required:
16GB (MINIMUM) USB 2.0 or 3.0 flash drives which are readily available at most office supply
retailers will be needed to perform these updates.
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
NOTES:
• The USB flash drives can be USB 2.0 or 3.0.
•
The USB flash drive MUST be reformatted to NTFS before loading any files to it. NTFS is
not the standard format on most USB flash drives.
•
The update files are not overly large but, during the reprogramming procedure, the head unit
backs up some files to the USB drive. For this reason, sufficient USB drive memory size is
required, especially for the High / Navigation units.
•
The flash drives should be dedicated to storing these reprogramming files only. Do NOT
use any flash drives which contains or requires the use of file management, encryption, file
backup or other software to function properly.
•
Re-format (see Step 2) any prior USBs you may have used for WTN -74R as that version of
software must no longer be installed. This update includes all WTN -74R updates.

Operation of the head unit after switching the ignition off and back on has been revised:
PREVIOUS Version: The head unit power is turned OFF by pressing the Power/Volume knob
for 4 or more seconds. On the next ignition ON, the display remains OFF / black while the audio
begins playing automatically. This was the prior characteristic operation.
NEW Version: The head unit power is turned OFF by pressing the Power/Volume knob for 4 or
more seconds. On the next ignition ON, the display remains OFF / black and the audio will also
be OFF until the Power/Volume knob is pressed to turn the head unit back ON.
NOTE:
•
•
The Mute function of the Power / Volume knob (a brief press and release of the Power /
Volume knob to mute audio output) is unchanged.
•
A “system reboot” function is initiated by pressing and holding the Power / Volume button for
10 seconds. This feature was included as part of the previous (11/2017) software update.
An enhancement of Voice Recognition feature has been made for improved HVAC system
interface and recognition of temperatures requested in Fahrenheit instead of Celsius. EXAMPLE:
“Set temperature to 75.” With the previous version, the system interpreted “75” as degrees
Celsius which would have been 167 degrees Fahrenheit and outside system parameters. As a
result, there was no response from the HVAC system.
Additional Symptoms and Enhancements addressed by previous updates and also included in
this latest (June 2019) update:
1- No streaming audio; when using the Pandora® app, there is no audio output.

2- “Media is loading” is displayed on the screen but, the media never completes loading.
3- The screen freezes when the STARLINK screen is displayed.
The following conditions were addressed in another previous software version update and
WTN-74R:
1- Radio station presets disappear (touch screen buttons return to “Initializing”).

2- STARLINK “Telematics Service in Progress” screen freezes.
3- Apple Car Play / Android Auto function does not operate (“No Device Connected”).
4- The complete guidance route can be displayed.
5- A Longitude and Latitude search feature has been added.
6- A “Beep” notification feature has been added for driving time and rest periods.
7- This latest (November 2018) update also includes a security enhancement.
For reference, the previously released WTN-74R symptoms are also provided below. The main
purpose of WTN-74R was to address display screen freeze-up during Back-Up Camera display (when
the shifter is in “R”). In addition, the screen may also freeze when either the Subaru STARLINK or
Disclaimer Caution / I Agree screen is displayed.
Continued...
Bulletin Number: 15-211-17R; Revised 06/26/19

The WTN-74R update also addressed these additional operational conditions:
1) After switching the vehicle (ACC or IGN) on, the display screen goes black with no audio output
and the hard key buttons are illuminated (on solid, or flashing / blinking).
2) Time of day displayed in the MFD is incorrect and the arrival time displayed in Navigation unit
is also incorrect.
3) The time in the MFD automatically reverts to a “default” setting, even after setting the time using
“Manual” mode.
4) Audio volume goes to maximum automatically after one click of the volume up button on the
steering wheel. In some cases, this condition may also occur without input from the operator.
Maximum volume is also displayed on the screen.
