SUBJECT: FOTA (Firmware Over-The-Air) Reprogramming for DENSO Gen 4 Audio / Navigation Infotainment Systems

 

INTRODUCTION:

This bulletin provides instruction for use of a new reprogramming procedure to optimize the Denso Gen 4 Audio and Navigation system utilized in the models listed above.  Firmware-over-the-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 secure Wi-Fi connection through a home network or the use of a secure Wi-Fi hotspot to create a connection to the update server.  Once connected, customers can easily obtain and install any available FOTA update to their infotainment system.  FOTA operation is conducted in two steps: download (from the server to the vehicle via Wi-Fi) and installation (internal to CP1 system in the vehicle).  This bulletin will focus on FOTA for Denso Gen 4 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 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 install it*
  • Updating the firmware using a USB flash drive by following the steps outlined in TSB 15-26120R “Reprogramming File Availability for Optimization of Gen 4 Denso CP1 Infotainment Systems” when FOTA cannot be performed due to the setup difficulties*.

* 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 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.  For additional details clarifying the scope of FOTA updates, review the 20MY Legacy/Outback Owner’s Manual Supplement’s additional information for the Center Information Display.  The information is also be downloadable from: https://www.subaru.com/ owners/index.html  See Appendix B 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.
