Intending to Update from 2.3.17109 to 3.4.23188

Roland97 · 3 October 2025 17:29

Hello everyone,

I have a recently purchased 2017 Ford Focus hatchback, and I would like to update its navigation system. However, several questions have arisen before I start the process.

My head unit’s current version is 2.3.17109, and I’d like to update it to the latest 3.4.23188 version.

I used the Interrogator Log to read the head unit’s data, but I ran into a few issues.
For some reason, the Syn3 updater reading throws an error when i open the interrogator log.
The APIM Type shows up as Non-Nav. What exactly is the difference between NAV and Non-Nav? (I know its a stupid question.) I can search for streets and start navigation without any problems, so I don’t fully understand the distinction between the two. Furthermore, the official Ford website doesn’t show a map update available as well for my vehicle, only the 3.0.23219 software version.
The previous owner did not mention that the head unit had ever been replaced.

Finally, if I decide to proceed with the update, can I go directly to the latest 3.4.23188 version, or are there any intermediate steps I need to perform first?

Thank you in advance for your help and answers!

Hello.

What error?, something about overlays?.

Basically, storage. NAV APIMs are 32GB for NA and 64 for EU. NO-NAV APIMs are 8 or 16 GB.

From the log you sent before, the APIM is JS7T-14G371-FDC, which is a NAV APIM for EU, 64GB.
Syn3updater says it’s NO-NAV since it can’t read the log properly, hence showing 0GB:

Initially since it’s already on above 2.2.17xxx, try if CarPlay and/or Android Auto works.
Since the vehicle is from 2017 everything should be good, but I would check that.

Also, a few things to consider:

There is an unsolved “issue” with Focus and Kuga running 3.4: the auto adjustment for the screen brightness does not work that well and makes the screen flicker. The only solution is to disable it, but that can only be done on an early 3.4.19xxx I believe.
Once you go to 3.4 you can’t go back to 3.0 or below.
As per our hardware db, APIM JS7T-14G371-FDC is not MY20 and can be reformatted. You should be good, and I’m using should because there’s always a small risk involved.

Roland97 · 4 October 2025 05:49

,The XML file you have selected does not contain the expected outpot
Syn3 Updater has determined you are on 2.3.10109 and may be using overlays
Syn3 Updater is unable to determine the configuration of your APIM”

Oh, I see. Thank you!

I’ve only tried CarPlay during these past few days, and it worked without any issues. I haven’t tried Android Auto yet.

So, if I understand correctly, if everything is working without a problem, is it not worth updating to the latest version? Or would it only be worthwhile to update the maps? (Although, I primarily use Waze via CarPlay.)

SaNdMaN · 4 October 2025 09:22

No need then, if Car Plays work so should Android Auto.

That’s up to you. Personally I have a wireless android auto dongle connected, so I see the Sync3 interface for about 30 seconds (if so) once I get into the car, then Android Auto takes over. My Sync3 version is 3.0 and maps are from 2015, I also own a Focus.

You can’t use Syn3updater to update just the maps on your current build, you can do that manually though, there’s a guide around that I can look for…

Roland97 · 5 October 2025 05:19

Which 3.0 version are you using? Also, are you satisfied with that version?

SaNdMaN · 5 October 2025 11:20

I’m on the latest 3.0, which is 3.0.23219 if I remember correctly…

Satisfied is a bit overkill, I hardly use it as an UI… Let me put it this way: for the things I need from it, which are:

listening to radio
using android auto
no weird flickering on the screen

then yes, I’m very satisfied with it… but again, I see the Sync3 UI for less than 30 seconds before android auto automatically starts when I enter the car…

Roland97 · 5 October 2025 16:46

Then I will stick with the current version as long as it works without issues.

Thank you very much for your help.

F150Chief · 6 October 2025 02:06

In case you change your mind and decide to update to the latest Sync 3.0 version, you will need to use the overlay removal tool first and upgrade to Sync version 2.2.17011 before you upgrade to Sync 3.0.23219.

If you decide to upgrade to Sync 3.4 this is not necessary.

DreeN06 · 16 October 2025 18:02

Hello!
Just for clarification I’m the Owner of the mentioned Focus and since then I have witnessed a few little glitchies. For example one time I was using the Apple Carplay just fine. I stopped the car then reignited it and suddenly the carplay was gone. No matter what I did it just didnt feel like coming back. The next day the issue has solved itself somehow and since then it works.
Because of that I’m interested in updating to 3.0.23219. The update will resolve any kind of further problems like this?

Thanks!

F150Chief · 17 October 2025 01:55

There is no guarantee it will solve the issue but there are some issues addressed with AA/CP. Unfortunately, Ford does not publish the actual data about the fixes. I have had that happen before on Sync 3.4, an earlier version, but have not seen that behaviour on the latest version.
