SubarueBay logo of America, Inc. (SubarueBay logo) is recalling certain 2017 model year Impreza vehicles with Harman
navigation/audio head units to update software affecting the operation of the rear view camera image.
DESCRIPTION OF THE SAFETY RISK
The rear view camera image may not display properly. More specifically, due to a software problem
within the infotainment unit, the following may occur:

During initial boot-up, a memory error might result in a blank screen; or
If multiple processes occur at the same time, the screen might freeze.

increased risk of injury or a crash.
DESCRIPTION OF THE REMEDY

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

INTRODUCTION:
The following information addresses reprogramming file availability and a software update
installation procedure to optimize the rear view camera feature of the new Harman Gen 3 audio
and Navigation head units utilized in the new 2017MY Impreza. 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 before proceeding.

These reprogramming files apply to the following audio / navigation head unit part numbers:
Multimedia System Type
Part Numbers
6.5 Inch Display Audio System (Base)
86201FL60A and 61A
8.0 Inch Display Audio System (Mid)

8.0 Inch Audio / Navigation System (High)
86271FL60A

Descriptive Features
No CD slot / Eject Button
Phone Button in Top Row Center
Map Button in Top Row Center

Materials Required:
3- 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. There are various types of USB flash drives
available from many suppliers. If the head unit does NOT recognize the USB drive
during the reprogramming process, it may be that the IC controller type used in the drive is not compatible. In such a case, a different USB drive may be required. While not all of their products may
be compatible, USB flash drives from Kingston, SanDisk, Transcend and Verbatim are suggested
products.
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:

All SOA Pre-Production Vehicles require a “full version” update be installed BEFORE this
update can be applied (extremely rare occurrence). Contact your FSE for assistance with any
Pre-Production Vehicles.

The USB flash drive can be USB 2.0 (High Speed USB) or 3.0 (Super Speed USB)

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 drive which contains or requires the use of file management, encryption, file backup or
other software to function properly.

Symptoms to be Addressed by These Reprogramming Files:
The main purpose of this campaign is to address display screen freeze-up during rear view camera
display (when the shifter is in “R”). In addition, the screen may also freeze when either the SubarueBay logo
STARLINK or Disclaimer Caution / I Agree is displayed.

IMPORTANT: Although the main purpose for this campaign is to address operational concerns
involving the rear view camera feature, software is also included in this update for the following
other 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
(Multi-Function Display) is incorrect and the arrival time displayed in Navigation units is also
incorrect.

3) The time in the MFD automatically reverts back 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.

SERVICE PROCEDURE / INFORMATION:
STEP 1- Verify the currently installed Software Version ID using the following steps:

From the HOME screen, touch “Settings”.

From the Settings > General screen, scroll down to and then touch “System Information”.
