##Patch Notes:
Symptoms Addressed By Update #4:
* System: * Reset CID screen (CCU) repeatedly resets every 3 minutes. *
CarPlay: * **Wireless conenction drops while using wireless CarPlay due
to external signal interference from surrounding facilities etc.** (only
applicable to HIGH and MID trim) * **During CarPlay handsfree call
receiving party is not able to hear the caller as the microphone data is
muted** * Android Auto * When wireless AndroidAuto connection failed,
the same connection failure error was displayed in all cases. Since it
was difficult to understand how to deal with the problem, the connection
failure error was divided into several phases. * 1st step: Bluetooth
connection phase * 2nd step: Confirmation phase of Wi-Fi connection
information * 3rd step: Wi-Fi connection and Android Auto connection
phase * Failure in the 1st step: Various error messages are displayed
to try the user to redo the connection procedure. * Failure in the 2nd
step: When an error occurs, an automatic retry is performed by internal
processing, and the screen indicates that a retry is in progress. *
Failure in the 3rd step: The timer for determining failure is too long,
so it is changed from 130 seconds to 45 seconds to shorten the time
until the error message is displayed. (only applicable to HIGH and MID

fails. (Caused by the USB connection mode connecting the Android device
to the on-board device not switching in the expected order) * Bluetooth
* Toggling the CarPlay ON/OFF switch multiple times on the Manage
Devices screen while the iPhone is connected via USB, may result in a
"Bluetooth connection unavailable" state. It is the same as a "CarPlay
connection unavailable" state. Bluetooth icon in the top right corner of
the CID screen may still indicate a connected state. * When multiple
Android Devices attempt to connect during ignition on, it may result in

two or more shortcuts of DMS/SRH/SRVD icons are set on the Home screen,
the order of icons changes from DMS to SRVD, SRH, VDC, AVH, and ISS. *
The AVH icons on the HOME screen are initially lined up next to the
ValetMode icon. However, in some cases they are placed at the top (upper
left corner of the first page) or next to the MAP icon. (only applicable
to HIGH and MID trim) * After switching the clock function to AUTO, the
CID screen display may become distorted. (only applicable to HIGH and
MID trim) * It may take excessive time to start the CID screen after
ignition on. * SXM * The first time ignition on after the CCU software
update added the SXM360 functionality, the SXM playback screen may

|THANK YOU the fucking muting during a CarPlay call might be fixed; it
|was driving me nuts. Praise the iSubaru
|u/Taylor_Script - 2 months
|
|I just recently got a 24 outback and noticed that about the 9 minute
|mark of a call I had to switch away and back to CarPlay for the other
|person to hear me. Is this the same issue? Would be great if it is as
|it is frustrating.
|u/Chippy569 - 2 months
|
|> s this the same issue? yes
|u/nealtronics - 1 month
|
|have you gotten the update installed yet?
|u/Dbc122 - 1 month
|
|Got it earlier this week and it’s great, haven’t had a single
|CarPlay issue so far. Immediately better. Took a 2 frigging hour
|wait at the dealer but done.
|u/nealtronics - 1 month
|
|I just got it done today and will report back tomorrow! First
|tech botched the update so they had to call in a Master Tech or
|Lead or someone who was able to get it done. Dropped the car off
|at 11AM and finally picked it up by 5:30PM. It will all be worth
|if it resolves the fucking CarPlay issue.
|u/nealtronics - 1 month
|
| Buying a brand new car and discovering this issue was
|devastating and it's insane most people will just live with it or
|crash their cars fiddling with their phones toggling
|CarPlay/Speaker ON/OFF as a workaround. Tested this out with
|two phones today iPhone 11 Pro and iPhone 13 - not a single
|problem no muting/disconnects. My wife got pissed off at me so
|she hung up after about 15 minutes in. So fucking relieved this
|is finally fixed!!!
|u/Rick91981 - 2 months

|Thanks for the info Chippy!
|u/Chippy569 - 2 months
|
|I thought of you when I bolded the starlink app being deleted lol
|u/Rick91981 - 2 months
|
|Haha it really is about time they got rid of it, caused way too
|much confusion for people!
|u/Krawltec - 2 months
|
|Now if only us folks in MA could get an OTA update. Since the systems
|locks us out of WiFi upgrade. And it’s a hassle schedule a day for the
|dealership. Especially when they try to charge you for it.
|u/Rick91981 - 2 months
|
|Tell them you're having problems with the infotainment freezing so
|they can classify it as warranty work and you won't be charged. Or
|diy it(not officially supported but lots of us have done it)
|gen6firmare.com might be a few days before the new files are
|available
|u/TomAustinBoston - 2 months
|
|u/Rick91981 can you describe the infotainment freezing a bit more
|so I can get them to classify it as warranty work and not charge
|me? (2024 Ascent Touring)? Thanks,
|u/Rick91981 - 2 months
|
|You just need to give them an issue for them to update it over
|warranty, don't need a ton of details. Tell them it's laggy, or
|if you want to specifically target something this update
|addresses, tell them you have issues with people not hearing you
|when using Carplay. If you're on android then just say your
|wife/husband has iPhone and it's a problem when they drive.
|You don't need to go crazy here, they just need a simple reason
|that a customer is having a problem. This way they can file it
|as warranty and get paid for their time from Subaru.
|u/romankphoto - 2 months
|
|IS the no OTA just MA thing, does OTA works in other places?
|u/Rick91981 - 2 months
|
|OTA will work in other states, but don't expect this update to be
|available anytime soon. OTA is usually a few months behind so
|it'll be a while. If you want it quicker, have the dealer do it
|or do it yourself(via unofficial methods)
|u/romankphoto - 2 months
|
|did it myself via USB, seems pretty straight forward
|u/Rick91981 - 2 months
|
|Yup, it's very easy. I haven't done this update yet but have
|done past ones.
|u/Chippy569 - 2 months
|
|for what it's worth, the new crosstrek ('24+) and new
|forester ('25+) and new WRX ('24+) and outbacks (and
|presumably Ascents) '25 and newer require a dealer scan
|tool and SSM5 to run the update.
|u/Rick91981 - 2 months
|
|Outback requires it for the '25 as well. Not sure if
|that's just a "do it this way because we recommend it" or
|a "we made programming changes so it cannot be done the
|old way"
|u/Chippy569 - 2 months
|
|the "software update" button in the dealer menu is
|nonexistent. and I just had a '25 ob in my bay right
|now so I just discovered this lol
|u/Rick91981 - 2 months
|
|Ah interesting, thanks for the info. So then they
|did make programming changes so it can't be done the
|old way. Well at least someone can't try it and end
|up breaking something by doing it the wrong method.
|u/Lotek_Hiker - 2 months
|
|Are there 'explain it to me like I'm a Labrador' installation
|instructions for USB?
|u/Chippy569 - 2 months
|
|Uhhh, sure. 1. Set up appointment at your local dealer. (Speak!) 2.
|Arrive at your appointment time. (Good boy/girl.) 3. Hang out in the
|lobby (Sit, stay) or go for a [walk]. 4. Approximately an hour later,
|enjoy your up-to-date firmware. (Treats!)
|u/Lotek_Hiker - 2 months
|
|Woof. Not exactly how to do it by USB, but thanks.
|u/Chippy569 - 2 months
|
|What random files you find on the internet, you use at your own
|risk. The new crosstreks and Foresters and WRXs require a dealer
|scan tool to perform the update.
|u/Omega_spartan - 2 months
|
|It’s too bad that they changed the flashing procedure. I was
|able to get the file from a legit source but you can’t access
|the update menu from the dealership menu now.
|u/rock962000 - 2 months
|
|I love that the first few of these newer style updates I've done, I
|somehow skipped past the big red dotted line box that states to verify
|the DCM is up to date when updating the CCU...... Thankfully they were
|up to date when re-checking. Flat rate will be the death of me
|u/Chippy569 - 2 months
|
|the DCMs pushed their own OTA updates over data, it'd be super weird
|to find one that isn't.
|u/rock962000 - 2 months
|
|I had one on a 23 Ascent recently that needed the DCM replaced
|because it had an older software version when performing the CCU
|software update. Granted it was the only one I've come across that
|was not up to date, but definitely makes me remember to check now.
|u/Cojaro - 2 months
|
|Do dealers update in-stock inventory when an update comes out? I'm
|picking up a '24 Ascent tomorrow.
|u/Chippy569 - 2 months
|
|No. We could with Harman radios, but Denso does not have a similar
|way for us to bill it as inventory.
|u/Carobu - 2 months
|
|I thought OTA updates were enabled in the last update? I still don't
|see it on my 24 Impreza.
|u/Chippy569 - 2 months
|
|They're enabled but subaru doesn't push the files to the OTA update
|system for a couple months after we get them on USB
|u/speedhounds - 1 month
|
|I got this update FB1SMM150-770 on 22 Legacy. Don’t know what changed
|u/Chippy569 - 1 month
|
|Your '22 is a CP1.0 hardware, so this thread won't apply in your
|case.
|u/Master-Bookkeeper438 - 1 month
|
|Hi, can you post these notes in plain text format? I wanted to copy
|them into text file but it comes over with blue weird formatting
|u/Chippy569 - 1 month
|
|This is as plain as reddit gets. Try old.reddit.com
|u/NowArgue - 1 month
|
|If you’re on a Windows PC, use Notepad to paste the text instead of
|Word. It automatically removes the formatting. Also, you can try
|pasting with Ctrl+Shift+V which attempts to paste without formatting,
|but doesn’t work with all programs.

|I was told today by the dealer that my 24 CTW with 800 miles on it
|“running version F91WMM053-880” is not part of the new update that you
|posted but since I am experiencing the same issues they will do a “
|Courtesy update” for me. They also told me that updates are only
|covered for 3/36 even if you bought the Subaru Gold warranty
|u/Chippy569 - 13 days
|
|Your dealer is very silly, Subaru is paying us to do updates during
|the PDI now, lol. F91 is one version old. Though they are also
|incorrect about SAS coverage, if you have a $100 deductible it might
|be more expensive to process the claim through SAS than whatever they
|charge to do an update.
|u/Carlluvscorinne - 13 days
|
|Thank you very much for the insight. They said they updated it as a
|“courtesy “ Here is the notes they put in the repair order https:/

|p&s=b6170c73db6e8a6273b0c589a60ab53f940e9bda
|u/Chippy569 - 13 days
|
|Yeah, that's a technically correct way to do it. From a legalese
|standpoint, it means they weren't able to duplicate the concern
|but performed a likely repair anyway. This really only matters if
|it becomes a "lemon law" car, where in the instance of "I've
|brought my car to the dealer for the same problem # times and
|they can't fix it" comes into play. Specifically written this
|way, it is not considered an attempted repair.
|u/Carlluvscorinne - 13 days
|
|Awesome, thanks for the explanation. Multimedia seems fine now
|so that’s what really matters.
