Hi everyone,

I would like to have the software of the head unit of my Impreza 2018 Sport (CAN) / Premium (US) updated to the latest version.

On my car the FOTA (Firmware Over-The-Air) update doesn't work. Looks like only 2018 Limited trim, and all 2019 to now have it working.

The current version installed is Rel1.17.08.20 which came in the car when I bought it. The new version could be one of these: Rel_A2.20.07.20, Rel_A2.20.18.20 or Rel_A2.20.28.20.

Here is the service bulletin that explains the firmware update: https://static.nhtsa.gov/odi/tsbs/2020/MC-10179424-0001.pdf

I could do it myself but I don't have a login for partners.subaru.com to download the correct file. Does someone here have?

I sent an e-mail to my dealer but he did not answered yet.

Thanks, all the best,
