After SYNC 3 update I still cannot get polish lang. on IPC

bw1 · December 17, 2025, 11:53pm

Hi, I am not sure is this topic is actually SYNC 3 related, but in every tutorial I saw people got polish language in IPC after sync update and forscan as-build modifying.

Below I will list what I’ve done:

Sync 3 update with cyanlabs updater
1.a - Red screen
There was an error during installation: Red screen + “error in 1U5T-14G658-AH-1644006443000.TAR.GZ”
1.b - I modified reformat content as below (I’ve deleted problematic file)
reformat.lst content:
VOICE=5U5T-14G391-AT_1660763323000.TAR.GZ
GRACENOTES=4U5T-14G423-AC_1615425645000.TAR.GZ
APPS=NU5T-14G381-AD_1689364279000.TAR.GZ
1.c SYNC finally booted with new version. Actually everything works well in it. Polish language is showing up, radio works. No issue here.
APIM / ACM / FCIM / IPC as-built config
With forscan I managed to change region, but when changing to PL language in SYNC3, GUI shows message “one or more modules do not support polish language”.
Tried with as-build from eu market mustangs, but IPC rejects that - forscan shows message like: “configuration incorrect” (it is not message about wrong checksum).
Portugeese =/= Polish
Yep, after modyfing IPC as-build data Portugeese showed up as option on my dash.
Does it make any sense?

Please help me understand if skipped files during sync3 update could affect my current issues with IPC.
If this is related to SYNC3 update, how to get polish language in instrument cluster screen (IPC)?

If your Mustang was an import NOT marketed as EU, but imported otherwise from US, the IPC would not support Polish language, If it was sold in EU as new, it likely would. I don’t know if you could flash the firmware in the IPC to support Polish. The APIM changes will not affect the IPC language, this is an IPC firmware change if it’s possible on your NA vehicle.

Ahhh, that makes sense now.

Does anyone know to change firmware of IPC?I have forscan.

F150Chief · December 18, 2025, 6:20pm

I have seen several threads about this on the FORScan forum site. You might try there.
