Archive: Update all versions of Ford Sync 3 to the latest Sync 3.4 (Build 3.4.19200)

Couple questions.

First: anyone pull this off on a 2018 Ford Expedition Platinum? I am stuck on V3.0 19205 I believe. After it's installed I can see Android Auto screens in the center instrument cluster (behind the steering wheel)? if so that is awesome :)

Second: if I am using US Nav, then I don't need the third USB stick? Just stick one for repartitioning then stick two with the US NAV version is enough right?

Third: I don't need to upgrade the APIM, right? No reason but I could reflash it to get the Calm Mode?

1. It will work on any sync 3 I'm sure someone has done it for a ford expedition.

2. Correct due to the lack of licenses for na maps we do a workaround.

3. Nope but if you can it's good to do so to get extra features.

Aa will show in the instrument cluster screen but it may need a Apim firmware update I'm not sure.

You need a wired els27 ( I think that's the model) then you need the experimental build of forscan due to the risk of this process via forscan compared to UCDS I won't provide any further details.

hi, Thanks for the detail replied. maybe a bit too detailed ;)

No this is a leaked ford official tool, the images are probably to stop any potential LCD burn in, although i'm not sure these displays are using a technology that is prone to this. the images are a bit odd though i have to admit, i guess since it's a factory tool they probably just did something to show it wasn't frozen.
It has to be official as all packages are signed by ford's cryptographic signature. strangely this tool does check if you have a compatible car but then continues anyway, could literally be a bug in the code or intentional, either way we can use it to get sync 3+ on our non 3+ compatible devices.

the DONTINDX file is exactly what it sounds like "Dont Index" it tells SYNC to just not index the USB and instead only process the update.

You can downgrade but the exact steps vary a lot, hopefully you took note of your IVSU's as that will make it a lost easier.

I can't answer what the differences are, 19200 appears to be what is used on new cars in showrooms according to reports., 19101 is the only one with a auto dim option, all others force it on with no choice to change it.

It is complicated for ford to update older units, the reformat tool, repartitions the system. they can't release an update due to too small partition sizes on the older variants.

Edit 1 : Yes this happens on default themes, not sure if it's a bug by ford and they never fixed it or it's intentional, personally i reckon the latter.

Edit 2 / 3 : You will likely need to set some setting in Forscan or UCDS, i can't advise with this as it's different depending on many factors, google your car and apim asbuilt.

Edit 4: honestly i don't know i only really use AA mostly.

Edit 5: i don't seem to have this issue,.

Thanks a lot for doing this. I'm about to proceed.

Just to be clear, both of the DONTINDX.MSA files are not necessary (for either usb 1 or 2). Because I can't find that file in either of the archives I downloaded.. I suppose the screenshot show's it in one of the steps but it says it's not necessary which is good since I don't have the file.

Not required for any

I believe the voice the data is street names and directions and things like that, general voice will be part of the base package.

I'm also wanting to upgrade the apim software. I believe it requires hardware that you have to purchase. From what I can tell it requires a usb to odb connector and some software called forscan.

I think this one will work with Forscan: https://smile.amazon.com/gp...
