FOTA (Firmware Over-The-Air) Reprogramming
for DENSO Gen 4.5 Audio Navigation Infotainment 		
Systems via DCM
INTRODUCTION:
This bulletin provides instruction for use of a new reprogramming procedure to optimize the
Denso Gen 4.5 Audio and Navigation system utilized in the models listed above. Firmware-overthe-air (FOTA) is a process where remote devices can receive updates to their operating firmware.
This process has become second nature with smartphones, tablets and many other connected
devices. FOTA for automotive infotainment systems was designed with an emphasis on customer
convenience. FOTA updates provide regular enhancements along with software patches as needed to
enhance the customer experience. The convenience factor comes not only with the supply of regular
updates and the enhancements they provide, but through customer control of when these updates are
downloaded and installed. The only requirement is a valid subscription to SUBARU STARLINK
Safety Plus, since the download of the software is performed via DCM. FOTA operation is
conducted in two steps: download (from the server to the vehicle via DCM) and installation (internal
to CP1.5 system in the vehicle). This bulletin will focus on FOTA for Denso Gen 4.5 audio systems
(MID) and audio-navigation systems (HIGH) which utilize the 11.6-inch touch-screen display.
Models with 7-inch dual screen display (Base) are not FOTA update capable.
This bulletin outlines the procedure for performing FOTA updates successfully. These procedures
involve:
•
Assisting customers with FOTA -related concerns if they have been unsuccessful in
performing the FOTA by themselves. (Possible vehicle or system concern.) *
•
Performing the FOTA update for customers who are not comfortable or need assistance with
performing it themselves but have requested the Retailer to install it*
•
Updating the firmware using a USB flash drive by following the steps outlined in TSB
15-305-22R “Reprogramming File Availability for Optimization of Gen 4.5 Denso CP1.5
Infotainment Systems” when FOTA cannot be performed due to the setup or eligibility
constraints*.
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.
Subaru of America, Inc. is
ISO 14001 Compliant

* NOTE: If a customer is simply requesting help with how to perform FOTA, provide a copy of the
appropriate customer instructions for FOTA available on Subarunet: Service Operations & Technical
> Forms/Downloads page.
See Appendix A later in this bulletin for more information.
It is VERY IMPORTANT to read and understand this information completely before proceeding.
NOTES:
•
REMINDER: FOTA is available for MID and HIGH (Navi) systems with 11.6-inch display
only.
•
The currently available FOTA firmware version is not the same version available to Retailers
for USB updating use. However, a system updated using FOTA can be further updated by
using the USB update procedure if additional updates are needed. For additional details
clarifying the scope of FOTA updates, review the applicable Owner’s Manual Supplement’s
additional information for the Center Information Display. The information is downloadable
from: https://www.subaru.com/ owners/index.html. See Appendix C below for more
information.
•
FOTA updates are for the system firmware 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 for more information.
Reference photos of each system faceplate are supplied below:
SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
The FOTA update process involves a remote downloading and installion the update firmware
therefore, time duration depends on signal strength and transfer rate performance. During installation,
the infotainment system’s functionality will be restricted.
