• Operation of the head unit after switching the ignition off and back on has been revised:
PREVIOUS Version: The head unit power is turned OFF by pressing the Power/Volume knob for 4 or more seconds. On the next ignition ON, the display remains OFF / black while the audio begins playing automatically. This was the prior characteristic operation.
NEW Version: The head unit power is turned OFF by pressing the Power/Volume knob for 4 or more seconds. On the next ignition ON, the display remains OFF / black and the audio will also be OFF until the Power/Volume knob is pressed to turn the head unit back ON.
NOTE:
• The Mute function of the Power / Volume knob (a brief press and release of the Power / Volume knob to mute audio output) is unchanged.
• A “system reboot” function is initiated by pressing and holding the Power / Volume button for 10 seconds. This feature was included as part of the previous (11/2017) software update.
• An enhancement of Voice Recognition feature has been made for improved HVAC system interface and recognition of temperatures requested in Fahrenheit instead of Celsius. EXAMPLE: “Set temperature to 75.” With the previous version, the system interpreted “75” as degrees Celsius which would have been 167 degrees Fahrenheit and outside system parameters. As a result, there was no response from the HVAC system.
Additional Symptoms and Enhancements addressed by previous updates and also included in this latest (July 2018) update:
1- No streaming audio. When using the Pandora® app, there is no audio output.

2- “Media is loading” is displayed on the screen but, the media never completes loading.
3- The screen freezes when the STARLINK screen is displayed.
NOTE: The following conditions were addressed in the previous software version update (and WTN-74R) but, this one update incorporates all prior updates.
1- Radio station presets disappear (touch screen buttons return to “Initializing”).

2- STARLINK “Telematics Service in Progress” screen freezes.
3- Apple Car Play / Android Auto function does not operate (“No Device Connected”).
4- The complete guidance route can be displayed.
5- A Longitude and Latitude search feature has been added.
6- A “Beep” notification feature has been added for driving time and rest periods.
For reference, the previously released WTN-74R symptoms are also provided below. The main purpose of WTN-74R was to address display screen freeze-up during Back-Up Camera display (when the shifter is in “R”). In addition, the screen may also freeze when either the Subaru STARLINK or Disclaimer Caution / I Agree screen is displayed.

The previously released WTN-74R updates also addressed these additional operational conditions:
1) After switching the vehicle (ACC or IGN) on, the display screen goes black with no audio output and the hard key buttons are illuminated (on solid, or flashing / blinking).
2) Time of day displayed in the MFD (Multi-Function Display) is incorrect and the arrival time displayed in Navigation units is also incorrect.
3) The time in the MFD automatically reverts to a “default” setting, even after setting the time using “Manual” mode.
4) Audio volume goes to maximum automatically after one click of the volume up button on the steering wheel. In some cases, this condition may also occur without input from the operator. Maximum volume is also displayed on the screen.

Nice to know ...

This would have been nice to know (eg, to reset with Android Auto) after last November's update, instead of turning the engine off & waiting three minutes:

...
• A “system reboot” function is initiated by pressing and holding the Power / Volume button for 10 seconds. This feature was included as part of the previous (11/2017) software update.

This is also nice, but a better solution would be to simply power up with the audio muted, if it was muted when powered down (like, you know, radios have worked for the last century):

• Operation of the head unit after switching the ignition off and back on has been revised:
PREVIOUS Version: The head unit power is turned OFF by pressing the Power/Volume knob for 4 or more seconds. On the next ignition ON, the display remains OFF / black while the audio begins playing automatically. This was the prior characteristic operation.
NEW Version: The head unit power is turned OFF by pressing the Power/Volume knob for 4 or more seconds. On the next ignition ON, the display remains OFF / black and the audio will also be OFF until the Power/Volume knob is pressed to turn the head unit back ON.

A real problem prior to last November's update; since then, just selecting another input & then reselecting the desired media, works. Hopefully, this fixes that:

...
2- “Media is loading” is displayed on the screen but, the media never completes loading.

 

Looks like I'm heading to my Subaru dealership this week... get er done!

 

This is great to know and really helpful. Thanks for the heads up.

 

Well dammit, I was just there end of last week!

I'll definitely get this done next time unless someone can dig up a copy of the upgrade files

 

Its simple to do yourself if so inclined.

 

Sure, but last I knew Subaru was being a lot more stingy with the files so I haven't seen a source for the recent versions.

 

I'm currently at the dealership and they're working on the update. Apparently, they're having problems downloading the software from Subaru's site...
They did confirm there is an update available.

We'll see how this goes.

 

Update done!

 

Just a cousin popping in from the XV forum, as I frequently do because all things Impreza are all things XV; I figured I’d finally make an account here.

Just wanted to say thanks for the update info. I’ve been tracking it for a month since it hit the European Outback forum. The buggy and weird firmware has been a thorn in all our sides.

 

YAY! Scheduled for Friday!

 

A note of caution:
Be prepared to wait awhile at your dealership for them to get the update.
Apparently, I was the first person to request this TSB at Stohlman Subaru in Tysons Corner, VA.

I was there for almost 3 hours, primarily because they were having major issues downloading the file.

Anywhoo, I'm still having issues with Android Auto disconnecting randomly on this update, so maybe it's just my phone that's the culprit.

 

Can anyone explain the procedure to do it yourself?

 

You can't do it yourself. You need the Subaru file on a flash drive and Subaru does not make it available to the public.

 

That is correct, unless someone posts the file somewhere public.

I spoke to one of the Subaru employees yesterday at the dealership and he said the same thing.
I asked if it would void the warranty if I tried to flash the OS myself, and he said, "Probably".

 

Getting mine done Wednesday morning. They assured me they will have the file downloaded and on flash ready to rock and roll.

 

I just had Android Auto quit completely last week. Coincidence?

 

Has anyone else gotten the update yet? I just got my car updated yesterday, and wow is there a huge difference in responsiveness now, I didn't have any weird issues before the update, but it's like a whole new radio after this latest update. They really outdid themselves in my eyes so far.

 

That's good to hear, but also annoying. I'm not going back out just for a radio update, but i want it

 

Got mine updated yesterday. I noticed the the volume indicator is bigger now when you change the volume and it almost seems like the bass has more boom to it also. I have the HK premium audio

 

I thought something looked different when I adjusted the volume today. Just had my car at the dealer for a few issues and they completed the update.

 

Just fyi, I'm still running Rel2.17.43.20 and I haven't experienced any problems since this update.

Before this update, it was just endless headaches like blank or black screens, no playback from USB, radio stations deleting on their own, back-up camera malfunctioning, etc.

 

Just curious, everyone who's getting the update, do you have a 2017 or 2018 model? I have an '18 that I got in January and I really haven't had any major issues. Had a couple of small bugs here and there but nothing that a restart of the car didn't fix. I wonder if my system has the version that you all are getting? I'll need to run out and check my version.


Edit: Just checked and I'm on Rel2.17.22.20. I'm hesitant to update since I haven't had any issues. I just had it into the dealer yesterday for service and it looks like they didn't update it.

 

I think the dealer will only update it if you ask them to. FYI if you try to get it updated once it is out of the bumper to bumper warranty it will cost around $70 here in Conneticut.
My car is a 2017 but should be the exact same radio in 2018

 

Yes, but don't you want to be able to turn the radio off and have it stay off the next time you start your car?

 

Yes, but don't you want to be able to turn the radio off and have it stay off the next time you start your car?

Really? They finally fixed that?? That's been my 1 gripe with the system. That and the fact that there are no auto door locks.

To all that have not done the update...DO IT. It will not hurt anything...only help and the head unit will perform better. I was running 2.17.43.20 (the latest and greatest) too and not a single issue but this update fixes a ton of stuff and you should get it without hesitation.

If you have a 2018, you do NOT have the latest as the update was just released on July 25th.

Guess I'll ask them to do it next week when I bring it back in for my warranty fixes.

Does this apply to ALL of the radios? I don't have the "HK Upgrade" but I think all the radios are actually made by HK, right? I have the standard Sport radio.

I ask because if that's the case I guess my dealer just isn't up on the latest versions. Just took the car in today to get them to order the strut tower caps and they said there was a software update for the radio. Previous version was 2-17-22-20, get the car back and now it's 2-17-43-20.

 

Yes, it applies to all radios...there is a LOW, MID and HIGH software version based on the headhunt you have in your trim level. 2.17.43.20 is outdated now.

 

NoData...

I made a thread a while back that I still had issues after a previous update that were addressed by the update. I ended up doing the factory reset on the head unit and all the issues disappeared. Take pics of your settings before resetting so you can set everything back up again quickly. For whatever reason, some need to do it for the fixes to take effect and others don't it seems.

 

I'd like to confirm: after the most recent update when you turn your radio off, then turn the ignition off, exit the car, re-enter the car and start the ignition, your radio does not automatically turn on? Mine does.

 

Try this for giggles:

1. With the radio on, hold down the volume/power know for a solid 10-15 seconds to see if it reboots.
2. If still having the issue, disconnect the positive battery terminal for 5-10 minutes and then reconnect and try again.

If the issue persists, go back to your dealer as you may need them to order you a new head unit.

 

Anyone else with the stock HK system think they tuned it again?
