SUBJECT: | FOTA (Firmware Over-The-Air) Reprogramming Procedure to Optimize Harman Gen 3.1 Audio / Navigation |
INTRODUCTION:
This bulletin provides information on a new reprogramming procedure (FOTA) to optimize the Harman Gen 3.1 Audio and Navigation head units (H/U) utilized in the models as listed above. Firmware-over-the-air (FOTA) is a process by which remote devices can receive updates to their operating software. This process has become second nature with smartphones, tablets and many other connected devices. FOTA for automotive infotainments systems has been designed with a similar type of customer convenience in mind. FOTA updates are designed to provide regular enhancements along with some software patches to our infotainment systems improving the user experience for our customers. The convenience factor comes not only with the supply of regular updates and the enhancements they provide but also through customer control of when these updates are applied by allowing them the freedom to choose when these updates are downloaded and installed. All that is required is a secure WiFi connection such as through a home network or the use of a secure WiFi hotspot to create a connection to the update server and any customer can obtain and install an available FOTA update to their infotainment head unit. In this bulletin we are focusing on FOTA for Harman Gen 3.1 MID-level audio systems and Gen 3.1 HIGH audio-navigation systems. BASE and BASE PLUS models are not FOTA capable. This bulletin will describe in greater detail the process for how FOTA is accomplished as well as provide insights and some procedures for how to resolve conditions that may arise as a result of audio or audio/ navigation head unit swaps or replacements performed outside of the Harman/ United Radio exchange unit program. The procedure will involve:
- Assisting customers with FOTA related concerns if they have been unsuccessful in performing the FOTA by themselves. (Possible vehicle or H/U concern.)*
- Performing the FOTA update for customers not comfortable or needing assistance with performing it themselves but have requested the Retailer install it.*
- Updating the software using a USB flash drive following the steps outlined in TSB 15-236-18R, “Reprogramming File Availability for Additional Optimization of Harman Gen 3 Audio and Navigation Head Units” when FOTA cannot be performed due to VIN/ head unit serial number mismatch.*
*NOTE: If a customer is simply requesting help with how to perform FOTA, NEVER share a copy of this bulletin. Instead, provide a copy of the appropriate customer instructions for FOTA. Detailed customer instructions for this procedure are available on the Subarunet: Service Operations & Technical > Forms/Downloads page. See Appendix B on pg. 17 for more information.
It is VERY IMPORTANT to read and understand this information completely before proceeding.
NOTES:
- On the models listed, FOTA is available for MID and HIGH (Navi) H/Us only.
- NOTE: For Gen 3.1, there is a new type of H/U known as BASE PLUS. BASE PLUS may look similar to a MID unit (both have a CD player) but, just like the BASE model, it is not FOTA capable. See the related Exchange Bulletin or Electronic Parts Catalog (EPC) to determine the H/U type.
- The available FOTA software version is usually the same as the USB version available to Retailers. But, since the USB software is always released to retailers before the FOTA version, availability of the latest FOTA version may be delayed.
- FOTA software updates are for the H/U software ONLY. Map updates are a separate function which the customer may update on their own by using either USB download or Map Over the Air Update (MOTA). Go to: subaru-maps.com
- On BRZ models, this update procedure is applicable to HIGH / Navigation (Navi) -equipped head units only.

INTRODUCTION:
This bulletin provides information on a new reprogramming procedure (FOTA) to optimize the
Harman Gen 3.1 Audio and Navigation head units (H/U) utilized in the models as listed above.
Firmware-over-the-air (FOTA) is a process by which remote devices can receive updates to their
operating software. This process has become second nature with smartphones, tablets and many
other connected devices. FOTA for automotive infotainments systems has been designed with
a similar type of customer convenience in mind. FOTA updates are designed to provide regular
enhancements along with some software patches to our infotainment systems improving the user
experience for our customers. The convenience factor comes not only with the supply of regular
updates and the enhancements they provide but also through customer control of when these updates
are applied by allowing them the freedom to choose when these updates are downloaded and
installed. All that is required is a secure WiFi connection such as through a home network or the use
of a secure WiFi hotspot to create a connection to the update server and any customer can obtain and
install an available FOTA update to their infotainment head unit. In this bulletin we are focusing on
FOTA for Harman Gen 3.1 MID-level audio systems and Gen 3.1 HIGH audio-navigation systems.
BASE and BASE PLUS models are not FOTA capable. This bulletin will describe in greater detail
the process for how FOTA is accomplished as well as provide insights and some procedures for
how to resolve conditions that may arise as a result of audio or audio/ navigation head unit swaps or
replacements performed outside of the Harman/ United Radio exchange unit program. The procedure
will involve:
• Assisting customers with FOTA related concerns if they have been unsuccessful in
performing the FOTA by themselves. (Possible vehicle or H/U concern.)*
• Performing the FOTA update for customers not comfortable or needing assistance with
performing it themselves but have requested the Retailer install it.*

• Updating the software using a USB flash drive following the steps outlined in
TSB 15-236-18R, “Reprogramming File Availability for Additional Optimization of
Harman Gen 3 Audio and Navigation Head Units” when FOTA cannot be performed due to
VIN/ head unit serial number mismatch.*
*NOTE: If a customer is simply requesting help with how to perform FOTA, NEVER share a copy
of this bulletin. Instead, provide a copy of the appropriate customer instructions for FOTA. Detailed
customer instructions for this procedure are available on the Subarunet: Service Operations &
Technical > Forms/Downloads page. See Appendix B on pg. 17 for more information.
It is VERY IMPORTANT to read and understand this information completely before proceeding.
NOTES:
• On the models listed, FOTA is available for MID and HIGH (Navi) H/Us only.
• NOTE: For Gen 3.1, there is a new type of H/U known as BASE PLUS. BASE PLUS may
look similar to a MID unit (both have a CD player) but, just like the BASE model, it is not
FOTA capable. See the related Exchange Bulletin or Electronic Parts Catalog (EPC) to
determine the H/U type.
• The available FOTA software version is usually the same as the USB version available
to Retailers. But, since the USB software is always released to retailers before the FOTA
version, availability of the latest FOTA version may be delayed.
• FOTA software updates are for the H/U software ONLY. Map updates are a separate function
which the customer may update on their own by using either USB download or Map Over the
Air Update (MOTA). Go to: dealer.subaru-maps.com
• On BRZ models, this update procedure is applicable to HIGH / Navigation (Navi) -equipped
head units only.

number shown on the unit matches the part number in the Electronic Parts Catalog (EPC) for the
specific VIN being repaired. Example photos are provided below for reference.
Set-Up Instructions and CAUTIONS:
• Move the vehicle to an outside location where the engine can be safely started and kept idling
during the update process.
• Never idle the vehicle in a closed space such as a garage, even if the garage door is kept
open.
• Once the vehicle is in a safe location, be sure the vehicle is in Park (CVT) or Neutral (MT)
and the parking brake is fully engaged.
• Open one or more windows to ensure fresh air is available.
• Stay with the vehicle until the update is completed.
• Unplug any devices, chargers, cables or other USB drives from the vehicle’s USB and power
ports.
Step 1: Check the Current Software Version Number
1-1) Turn the engine ON. When the H/U powers on, press “I Agree”.
Once audio start-up completes, press the HOME button and select “Settings”.
1-2) From the General screen, select “System Information” to check current software version.
(The pictures below are for illustration only and do not show the latest software version
information.)

• If the current software version is Rel_UK.22.49.70, Rel_UL.23.13.70 or Rel_UG.23.16.70
STOP as the head unit has the latest version installed and no further action is needed.
• Confirm the vehicle history to see if any H/U replacement has occurred in the past. If a new
H/U was installed (part number listed in claim information) or if the H/U was swapped from
another vehicle at any time, the H/U serial number must be captured and entered during
claim submission to ensure compatibility for future FOTA updates. REMINDER: H/U
R&R is necessary to access the Serial Number label. See the H/U serial number sample
photos presented on page 11 for reference.
Step 2: Required Preparation before Initiating the FOTA Update
NOTE: As part of this software update, the H/U will delete all the customer’s radio station presets
and change the volume settings to a default volume level. NOTE: If the radio volume is turned down
during the update process, the volume may seem suddenly very loud once the update completes. This
is normal operation. Always note the customer’s radio station presets and volume settings and be
sure to reset them after updating is completed.
TIP: Taking photos of the screens may be easier than writing down the contents of each.
2-1) Record all the preset stations saved by the customer.
2-1-1) Confirm the driver profile (example shows “Default” as driver profile).
2-1-2) Go to the Radio screen.
2-1-3) Record the saved preset stations (SXM, AM, and FM) (example shows #1: FM87.7 #2:
FM92.7…).
NOTE: Make sure to check the next screen by scrolling (pressing the right arrow > button).
