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. These files do NOT include Map Update data. It is VERY
IMPORTANT to read and understand this information completely to understand all changes from
prior releases before proceeding. A time line chart along with a complete list of all the conditions
addressed by this and previous Harman 3.0 software updates is provided in “Appendix A” located at
the end of this bulletin.
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.
If a Map update is pending, please follow the instructions posted on Subarunet: Service
Operations & Technical > Forms/Downloads > Navigation System Map Updates and select the
applicable link.
•
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.
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.

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.
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.
