I tried having the dealer flash it but they seemed completely incompetent. First telling my they couldn't find a TSB for my car, then when I shared the specific number they said they found it but when I checked they had downloaded an old version from August 2018 that didn't fix my SiriusXM issue and sent me on my way. Thinking that returning to them would be another circus I started digging online and found the documents / updates!



You all can access this too from the Subaru Technical Information System website which looks like it's run by SOA:



https://techinfo.subaru.com/stis/#/



For $35 they allow users 3-day access to all of their technical documents! This includes TSB's, Head Unit Updates, even the dealer Service Repair Manual! I registered and spent the weekend downloading as many PDF's & Updates as I could for my Subaru. In the TSB is a link to the download page for the software updates.



I'm pretty good with computers so feeling I could probably do a better job than the average mechanic I dug around myself (thinking about it, shouldn’t there be at least one computer tech at dealers to work jobs like these and not the guys doing the wrenching?).



The update was successful and my SiriusXM issue was fixed. Part 1 takes 15 minutes to download and 2 minutes after reboot, Part 2 takes 10 minutes to download and 5 minutes after reboot. You need a 2GB min - 4GB Max flash drive which I had to buy on eBay since I had nothing that small. They recommend a battery maintainer so that the voltage doesn't drop while updating. I used my generic one on the 12V 2A trickle charge setting which maintained 12.3V through the update. You can't just leave the car running as the TSB says the update will abort if the voltage rises above 14.5V which my alternator would spike at 14.7V. You don't want a bricked HU.



If you chizzlers are too cheap to pay $35 for the software directly from SOA and this forum allows I did download all of the Jan 30 '19 files for each year / model. I will only respond to a request in a PM with you specifying the EXACT software version you need from the linked PDF (ex OU9312) as well as a link to a shared folder on YOUR google drive so that I can upload. PLEASE ALSO MAKE SURE PERMISSIONS ALLOW GUESTS TO UPLOAD. If you are unaware how to do this you probably shouldn't be flashing the updates in the first place :P. Once you get the file take a backup to your local machine so that if I clear older files to free up space you don't lose the updates. I make no promises that these updates will work and take no responsibility if you brick your HU. Mon-Thurs I am at my computer 9-6pm. If you msg me outside of that expect a delayed response. So the forum limits PDF attachments to 1.22MB but I was able to find the latest revision of 15-205-16R dated January 30th 2019 and attach the first two pages outlining the fixes as well as the software versions here.I tried having the dealer flash it but they seemed completely incompetent.
