Ask your dealer?

Internet says UL vs UK regions is Latin America/global vs North America.

The 2025 is of course newer.

Internet warned of ensuring your head unit can take the N.A. version hence best to check with the dealer.

 

Thanks. So it sounds like my current release is a global release and the letter is referencing a North American version. I feel that if Subaru sends targeted emails to customers referencing their specific VINs instructing them to perform updates on their own, Subaru should supply or reference all the information the customer needs to do the update in the email including the check you mentioned.

I was a little gun-shy about applying updates after receiving a letter in February of this year extending the warranty on the head unit due to what sounded like a lot of problems that seemed to be software related. My unit has been acting fine for over four years but I didn't apply any of the three 2024 updates. This has me wondering if any of those updates introduced problems.

I'm going to hold off doing this one until more people have tried the current update before I do anything more about it.

 

I got the same message when I tried to install the update on my 2023 Crosstrek. Hopefully someone posts a dealer response here.

 

The update failed and now my console is not working. No radio and nothing.

 

I never update anything—and it all still works. That goes for phones, tablets, cars. If it’s running fine, I leave it alone.

 

I wish Subaru would explain what was being fixed with the updates they send. I'd like to know what components are being updated and for what reason. That way I can better judge whether or not I want to apply the update. If it was for better routing logic in Subaru's navigation app I'd be happy to apply it. If it was for safety reasons they should definitely let the customer know when they send the notice.

 

Here is info on the update.

Rel_UK.25.04.70 Details

 

Thanks. I don't have either of the problems this bulletin says the update addresses. Also, the procedure mentioned in this bulletin seems way more complicated than the procedure that Subaru sent to customers to perform the update over wifi. I will pass on doing the update for now.

 

Lol they typo Harman as "Harmon".

 

TCL - The procedure in the service bulletin is normally done at the dealership. The OTA procedure is normally not available for a few months. Subaru normally publishes a second Service Bulletin, 15-256-19R, when the OTA procedure is available. As a note, UL firmware versions are for Nav systems.

 

Thanks for that info. It's unfortunate that Subaru didn't explain the OTA delay when they sent the email to the customers asking them to perform the procedure. Their customer service number at the bottom of the email may be getting a lot of calls now . I tried calling before I started this thread and after I was transferred to the correct department the phone just rang and rang until it hung up on me.

 

I just received an email from Subaru of America requesting me to apply the July update Rel_UK.25.04.70 but when I started the update procedure it said my device software was already up to date despite it showing a different update number than specified in the update documentation. Mine showed Rel_UL.23.13.70 before and after the attempted update. The vehicle is a 2021 Crosstrek Limited and I don't have a Starlink subscription or whatever they are now calling it.

I did not attempt to apply the updates that I was notified about in 2024 because we were in between houses living in a short-term apartment and did not have ready access to wifi in the parking lot.

Has anyone else tried to apply this update and had a similar issue?

Thanks in advance.

Yes. I have the same software version as you. Connecting to a WiFi hotspot and trying to update generates an "update failed. Retry?" message. When I called my dealer he suggested I disconnect the battery so as to completely reset the HU and try again. Will try that eventually.

 

I don't recall getting an "update failed message". The procedure I followed came from a PDF file linked to in Subaru of America's email. When I came to the step where it said to press the "check for updates" selection I got this message:

 

I updated my 2019 BRZ with the current update OTA on July 16, 2025 after the third try.

 

What was the failure mechanism on the 1st two attempts?

 

I got the screen that said : "Software Up to Date" twice even though my installed software was the previous version. I reset my clock to the current time (off by 1 minute) and the current update downloaded and installed with no problem in about 10 minutes. I don't know if resetting the clock made any differance, but the instructions state that the clock must display the current time, so I reset it.

 

woo, will check it out...

 

I'll let you know after I turn on my 2021 Crosstrek Ltd. wi-fi toggle and check for an update.

 

Up to date!

tried updating my 2020 and it wouldn’t update, as of 7/25 I have no issue…
I think we can say”if it ain’t broke, don’t fix it.

 

Breaking News! A software update is now available on my 2021 Crosstrek Limited e-mail received @ 11:46am EST.

 

Can you do it yourself or dealer?

 

This will be my third update since purch. new Dec. 18, '21. Toggle wifi on and then update - automatic/ no dealer.

 

I just did that very update. I had to sit in the garage and noodle with settings. What finally worked was to switch to a different Wi-Fi connection, then switch back to my usual Wi-Fi setting. AND get logged back into Aha app. Then check for updates. It cycled through doing 4 updates. Now it shows the correct system information.

 

I got the same email for our '22 Crosstrek. I'm holding off for now. Odd that they can track mileage, tire pressure, etc. etc., but they want us to do our own system updates? I have the system set to automatically do updates, but why now do I have to do it? Maybe it's to generate biz for the service departments. Edit: I read the bulletin that the user so kindly posted above. I rarely use the head unit for anything other than the basic radio and the aux feature where I run the audio for my Uniden scanner.

 

I don't believe there's a hidden agenda on Subaru's part. If you're already set to automatic update, then as long as you have connected before, It's already done.

 

I believe you can have auto check and auto download, but you still have to initiate the installation phase.

 

Just did update on '21 limited. Settings were set to automatic download so all I had to do was turn on the wifi then download when prompted and it started automatically.

 

Got my email today.

Updated OTA using iphone hotspot.

Would anyone have the link to / the actual file of Rel_UK.25.04.70 ? Will try updating it via USB ...

 

Hasn't it been noted that Subaru often doesn't make updates available for the owner to manually install?
