The audio unit model number is displayed on the lower right of the faceplate as shown below.

To confirm if this bulletin applies, press the “Talk” switch on the steering wheel and listen to the voice which will provide some basic information, instructions and a list of options to select from.

SELECT LANGUAGE

 

  • After selecting the language, “Welcome!” is displayed. The unit should automatically display the Setup / Pair Phone screen next.

  • If the system does not automatically display the Setup / Pair Phone screen, the update files to reprogram the audio unit will likely need to be installed.

Software Version Check / Reprogramming Procedure:

  • Cycle the ignition off then back on.
  • Without turning on the audio unit (blank / black screen), press and HOLD the TEXT button while pressing the station preset buttons 5 & 6 simultaneously. The current software version will be displayed as shown below, right.

  • If the 4th, 5th and 6th digits of the version ID number displayed are 504 as shown in the photo above, the unit must be updated. If they are 505 or higher and the system does not automatically display the Setup / Pair Phone screen, the audio unit will need to be replaced with an exchange unit from Clarion.

VERY IMPORTANT:  If an exchange is determined to be necessary, a detailed description of the problem MUST be supplied in the space provided on the Exchange Form.

 

IF REPROGRAMMING IS REQUIRED:

Materials Required:

1 empty, USB 2.0 (do NOT use USB 3.0) storage device (flash drive) will be needed to perform the update procedure.  The device should be dedicated to storing and transferring these updating files only.  It must be a minimum of 2GB in size and contain a FAT32 file format before downloading the update files onto it.  The following recommended and readily-available devices include: Verbatim® model# 97002, PQI® model# U273 and Kingston® model# DTSE9.

(SOA).  If the GR8 indicates the vehicle’s battery must be charged, charge the battery using the GR8 before proceeding to update the audio unit while using the Power Supply Mode.

  1. I have a Subaru Impreza 2011 with the CZ424L1 head unit with software version «M 272608V071»
    Would this firmware update work for me? Or do i need something else?

  2. Hi

    I have a 2011 Forester. HU number is CP 225K1, for which I find no info whatsoever. My BT connection keeps on dropping for no reason.

    My firmware version is M 272608V071. The closest thing I could find is the 470-2725-11-V074_MainMicom-USA.mot, but it seems that version is a little different (M 272511V074).

    Is it advisable to use this update? I scared I turn the thing into a brick.

    Reply
    • So I did the update.

      The good news is the BT issues seem to be sorted.

      The bad news is, seeing that the firmware is for left-hand drive USA models, my right hand drive unit’s controls are now the other way round… Tuner is now On/Off, volume is tuner… >_<

  3. What would far more useful if Subaru puts out a firmware upgrade to support .OGG/Vorbis and .FLAC and WMA lossless that is found on Tesla, Honda, all Boeing passenger aircraft and Nissan, Opal and Mercedes. So do most of the Chinese car manufacturers. So does Apple and Android.

    What is infuriating is that Clarion (who is Subaru’s OEM ) offers this out of the gate with the NX706. It as if Subaru deliberately crippled the entertainment system playing from USB. Even the manual refers to WMA, but skips over which of the three variants of WMA work.

    Disfigures an otherwise excellent car and makes it third rate rather than a simple, royalty free couple of CODECS being added in (that Clarion already has in its libraries).

  4. Why isn’t there a recall on this bluetooth pairing problem for 2014-2015 Subaru Foresters? It seems that it is a common problem for lots of peoplel.

    Reply
    • I have a 2015 Subaru Forester, I purchased new. I have a CF605UL and I checked it to see what the software version was. It came back as 604. This means it needs an exchange unit from Clarion according to what I have read. I have taken car to Subaru dealer and they want 1500.00 to replace head unit. The blue tooth has not worked correctly since I bought vehicle, but I didn’t realize it at the time. Now, I am 3 months past my warranty so no one will make good on this. How do I rectify this situation? It seems like a similar problem with many 2015 Foresters.

  5. I’m hoping someone can help here. I also have the CF225KM Forester 2014 radio with software version M347704V081, and I have the exact same issue with the display showing BT-A PLEASE WAIT. Bluetooth on this thing just won’t work. I’ve tried disconnecting my car battery to reset it (for up to an hour) but this doesn’t fix. Does anyone have a firmware update for this head unit that I could try to install? I’ve taken my car to two Subaru dealerships and they’ve been unable to assist. Could we get in touch via email, oemdtc? ?

  7. Hello, trying to locate firmware update for CF625UM, the link in this article is no longer valid. Thank you in advance.

  8. Thank you. Was hoping not to go that route as I am sure there will be a significant charge for a unit that doesn’t work. The updated software won’t work? Again… Thank you.
