Hello! I am creating this thread as a how-to guide for people with the 2016 Forester Non-Nav on how to update their head-unit. This is mainly for people out of warranty, as if you are under the 3 year/36,000 mile (which ever comes first) warranty, the dealer "should" do it for you. The trend (from reading online) seems like most dealers are not aware of this update, or may not think it is worth the effort (remember they try to maximize profit based on how much labor time/charge SoA (Subaru of America) assigns the work, and how much time it actually takes them). In other words, even if SoA assigns a 1 hour labor designation for a belt replacement, a tech who has done it a bunch of times and is skilled enough to do it in 5 minutes would be getting paid for the completion of the job (not necessarily the time spent). This update is given 0.6 hrs by SoA, but I believe if one were doing it for the first time, 0.6 hrs is extremely optimistic.If you are under warranty and can prove that your head-unit is not up-to-date (you can tell by going into diagnosis mode > service info > version info > DA push and comparing the Nor/eSD numbers with those in the TSB - if they match the TSB file name numbers, you are up-to-date), if your dealer says it is "not necessary," you can escalate the issue with Subaru of America to have them pressure your dealer into doing it. It is not an issue of whether or not it is "necessary" as it has an assigned labor time, and operation number (A031-128) that you can see on page 20 of the TSB file. I just emailed Subaru of America this a two days ago and they said if the head-unit is not up-to-date and the dealer says it is not necessary, the dealer still has to do it.I have not been able to find a guide on how to perform this update anywhere on the Internet in the past week (much less any update files). I estimate that Subaru changed Subarunet to only be accessible with a login (only Subaru employees have one - you cannot "register") in early 2017 (you can tell from reddit question ages and old links to update files). Consequently, the update files that were once available to the public with Technical service bulletin 15-205-16 are no longer available.The link that used to work up until the end of 2016 was https://content.subarunet.com/snet/business/service/forms/audio_downloads.htm . It now gives you a 404 error.Subaru employees/technicians now login via https://www.subarunet.com/ . It seems like they would look for something along the lines of Service>>Forms / Downloads>>Downloads for Audio/Navi (from 15-205-16 TSB) if they were actually performing the update for you.The reason why I said this guide is for people with the 2016 forester with non-nav headunit is because I have just recently gotten access to [only] these files and will be posting them in a link at the end for anyone interested to download. You are free to use this guide if you have a different year/navigation head-unit, but most of the information in this post is also in the TSB guide.I am uploading these links assuming I will not be given a DMCA take-down notice.It seems like the reason why no one has their own specific files, much less the other vehicle files is because when people go to get their head-units updated at the dealer, the technician does not share their USB with the customer at any point.Of course someone could have downloaded all of the update files back when they were public in 2016, but at ~300 MB per file, it is highly unlikely anyone would have download more than what they needed, or kept the files after they did the update themselves.The best person to contact for files however is someone on the Subaru Legacy forums . You need to send him a PM with your email address and the specific file name of the update files you need (e.g. If I had a 2016 Outback with navigation, I would ask in the PM for NU9309_USB_1st.exe and NU9309_USB_2nd.exe).If you do not send specify the specific file name, do not be surprised to not get a response back as the last few pages of the thread are people basically begging for files.I asked him what files he had and he said he mostly has files for the legacy/outback so there's a chance he gets back to you and says he does not have the file you need.Partial how-to guide (should be used in conjunction with TSB PDF file):Download the TSB 15-205-16. Follow the directions to see if you are up-to-date.To get into diagnostics mode, hold the home touch-sensor button, then press the Audio/Tune knob 5 times. From there, click the following: Service Information > Version Information > PUSH (to the right of DA).Compare numbers for Nor/eSD with the update files for your specific vehicle in the TSB (e.g. if you have a 2016 forester with non-nav, Nor/eSD will say OU9909 - it matches the table entry so it is up-to-date).In the case the number in Nor/eSD do not match the table values for your specific vehicle, you are not up-to-date. If you have a 2016 forester with no navigation, congrats, you got lucky and can just download the files located below. If not, you will have to get into contact with Jdog81 and hope he has your file and decides to email you a link to download the files (~300 MB each).Once you have the files, extract them to two folders (I just did two folders named update 1, update 2). The reason why is because you have to copy over the extracted files over to a FAT32 formatted USB (usually old USB's that are <4 GBs - the newer ones don't even have an option to format at FAT32. The newer/larger USBs are usually NTFS or exFAT. These will NOT be recognized by your car when you plug them in) one update folder at a time to update (it is a two-step update).*USB drive has to be formatted as FAT32 (my computer > right click USB drive > format > file system > select FAT32). Make sure the USB drive is empty except for the extracted update filesI have read of people online getting drives that are larger than the 4GB limit on the TSB to work, but I think FAT32 is non-negotiable (car can't recognize any other file system)*There can only be ONE Update File stored on each flash drive or the update procedure will not work. If you see more than one Update File stored, start over by re-formatting the flash drive again and reloading the Update File you are trying to install.Assuming you moved the files over to a USB you digged around your house for, you plug it into the car's USB port, open diagnostics mode, then follow the TSB instructions on updating. At the end, you can confirm you have completed both update files successfully by either checking the Nor/eSD version #'s , or by just going trying to run the update again. You will see a page like this Here is a reddit comment thread that shows the process of how I figured all of this out (I am reddit user jkxs). Some information will probably be repeated, but if you're really interested...Lastly, if you found this guide to be helpful, please give me and jdog81 some credit when sharing this (instead of just copy pasting it somewhere, please share the thread link). I was only able to receive the update files due to jdog81 and so without him, I would have never wrote this guide. Please feel free to share your experiences in this thread and fill out the poll! If you were able to get files from jdog81, please post what specific file names you got so someone in the future may contact you if they need it as well. If jdog81 said he did not have your specific files, please also share what files you requested so jdog81 does not get 500 messages asking for files he has already said he does not have.I'm not sure if sharing this with Subaru of America or your dealer is the best idea, but at the same time, I don't think I'm doing anything wrong sharing DIY information on files that used to be public. I am going to my dealer in two days (reoccuring TPMS issue) and see if I can get more update files for you guys, but I probably won't get them considering I would need to use their login, how big the files are (300 MB each) and how many total there are (28). That's 26 files, or ~8 GB of files!!!Edit:This area is for me to confirm files that jdog81 has successfully sent people:OU9016_USB_1st.exe and OU9016_USB_2nd.exe (2015 Legacy/Outback without NAV)Also to add files for other years/models/NAV:2016 WRX with NAV: NU9208_USB_1st.exe and NU9208_USB_2nd.exe OU9019_USB_1st.exe and OU9019_USB_2nd.exe (2015 Legacy without NAV)For the Gracenote install, once you have extracted the files, make sure the only folder on your USB is gracenote_data (when you first extract it is GN_NU_7633/gracenote_data so just copy paste the gracenote_data folder onto your USB. It will not recognize the USB files if you extract the files straight to the USB as your car is looking for the folder named "gracenote_data". In other words, it is not "smart enough" to detect that gracenote_data is in that GN_NU_7633 folder.)
