8289 Views 11 Replies 7 Participants Last post by  walker
The purpose of this thread is to document the update history for the Subaru Outback Gen 4.5 Denso CP1.5 infotainment. It will serve as a record of the updates and a general lookup/destination for reference in other threads.

This thread is not intended for any lengthy discussion around firmware. This thread does not benefit from extended discussion or input here. Information is gathered from other threads, and consolidated here fore reference. This helps those that have not spent time, or do not want to spend time, reading through several other, very long threads

Please do not clutter this one up. See links below for better places to discuss that stuff. Things there may end up here, in summary form. There is already a dedicated thread for general discussion of the 2023 software - installation, updating, bugs, problems, etc. For further information, see the CP1.5 software thread

NOTE: Gen 4.5 is in the title of the TSB, and refers to the infotainment unit, not the generation of the outback.

What This Thread is NOT About:

Discussions around:
  • recalls
  • issues / problems
  • annoyances
  • help with operating
  • help installing firmware
  • your experience installing software
  • new features found in an update
  • should dealers install software
  • general software questions
  • etc
belong in other threads elsewhere on the site, as those threads already have more focused, and substantial, discussion.

Frequently Asked Questions

What is Different Between the Gen 4.5 Denso CP1 and CP1.5 Version Units?

No idea. It's different firmware, and it's now listed in a DIFFERENT technical service bulletin, where the 2020-2022 CP1 units are all listed under their own TSB. That seems significant. For purposes of this thread, it's not important. A good place to ponder the question would be here in the CP 1.5 software thread.

How Do I Identify My CCM (Infotainment Unit) Software Version/Level?
Easy! Follow these steps.

Product Communication Device Mobile phone Portable communications device Mobile device

Version Numbering:
  • The first four digits identify the hardware revision of the unit. Each model year has a different hardware identifier, and some models within a model year may be different.
  • The 5th digit is either an H,M or B, identifying the level of that hardware unit
  • The 6th digit is always the letter M
  • The last 6 digits is the software version
2023 Model Year
F61WHMxxx-xxx(High model software)
F61WMMxxx-xxx(Mid model software)
F61WBMxxx-xxx(Base model software)

Why Isn't the Wilderness Model Listed?
The hardware identifier for the wilderness trim is the same as for the other trims in 2023. There is no different hardware version identifier as the 2022 had. The new update is designed to fit on one USB, with different sub directories, so that you only use the one USB stick to update multiple trims. No longer have to worry about putting the wrong files on there, just create the USB and it works for all of them.

What Does the High/Mid/Base Level Indicate?
The High and Mid labels are for the 11.6” screen units. High is with Navigation, Mid does not have Navigation.
Base is the dual 7” screen units.

Because the purpose of this thread is different than the purpose of that thread.

This is a reference thread. I'll update the first post and hopefully make that a little more clear for others.

The first post in this thread I'll keep up to date as updates come out. like a do for four other threads, just like this one (firmware reference threads). I won't post updates in the other one, it's for discussion and other stuff. I might post things like "hey, there is an update to the TSB, might be some new firmware out", that sort of thing.

Please don't clutter this one up, it's more for ease of reference and summary, especially for those that don't follow the longer software threads regularly.

Thank you in advance!

Sorry, but I’m not seeing it. In the 2020-future forum?

Gotcha. Yes I looked on the firmware site for the 23 but only found January. Mine was built February 14, so I’ll be doing the March update once the files become available. I’ve also asked my service manager but he hasn’t responded yet.
Updated my 2023 ob wilderness over the weekend. Took about 10 minutes to complete. Now waiting for them to add avh to the options like the 22 got

let them know in the chat thread, not here. This isn't a thread on how to install this, or if it worked right, and so on. Thanks!

There's one similar thread already pinned, at least I think. I'm not that up on Gen 6 SW; is a thread merger appropriate?

I am not a mod here so can't do any changes here ....
I you want something changed, report it to us - personally speaking I don't read much of this forum, given I own a Gen 3.

no - this thread is to document changes and the TSB specifically. I added a few other items to it, as information is difficult to find in the main chat thread. This is meant to be a consolidated reference thread, where people can come and find the information without digging through several other threads.

It's not meant as a thread which gets information from discussion within the thread itself. Some want it pinned because it has the information they want without going through hundreds of replies in those other threads.

for this one, and a few others, it would be nice to be able to update the very first post and lock any other replies to keep this one (and a few others l have like this one) free of replies that belong in those other threads, to keep it clean
