Updating APIM Firmware (Calibration Files)

You can safely go to:
3.0 APIM NAV & NON-NAV Unit Firmware (Production Release, 2017-Pre-2018.5, H-Early J Series)
(Originally Found On 2017/Early 2018 Units That Ship with 2 USB Ports on Back)
GB5T-14G376-AA
HB5T-14G374-CA
HB5T-14G375-DA or HB5T-14G375-FA (HB5T-14G375-CA NON-NAV)
GB5T-14G379-AA
HB5T-14G379-BA

Thanks, I will give those a shot this evening. I was using the 15UT ones.

Edit: The above files worked for me. They didn’t initially due to only loading the cal and strategy. After selecting all four, and updating, everything updated as it should. Calm screen now stays so I guess I’m on MY18.5. Thanks again

F150boss greetings from Colombia, I was calibrating the APIM module of my ford fistes titanium model 2016 without navigation but it was not possible the screen stayed black and I have problems finding a place to download the original calibration files.

I am using an OBDLINK EX adapter
I used FORscan 2.4.6 to update the firmware in APIM.

THIS IS THE VERSION I HAD PREVIOUSLY

PLEASE I NEED YOUR HELP, HOW CAN YOU GUIDE ME TO CALIBRATE ELAPIM WITH THE ORIGINAL FACTORY FILES

Oh man. I need to try this! I have a 14 foST that I upgraded to sync3, and the screen has been fli keyring for the last year. It drives me insane. I even replaced the lcd to see if that would fix it.

Just wanted to chime in here with @bookemdano 's previous post a couple months back:

Receently picked up an early build H model APIM (Jan '17 build date, both USB ports populated) and was successful in getting it updated to the -DA level calibration. With the illumination gateway set to C1MCA for my C-Max (and likely the same for other Focus based vehicles) the Auto dim toggle is persistent and functional on the latest 22110 build of Sync. Enabled, works the same as we’re used to with the flickering and all. Turned off, brightness stays unchanged short of the Day/Night mode switching stuff.

Anybody saw this before? I had no part number and Calibration level so i cant updating my APIM Calibration Files. Sync Software is the newest. I also havent a “APIM Module firmware update Window” in newest Forscan beta.

Also as Picture the backsite of my APIM. I bought a Mustang 2015 US with Sync 2 and upgrade it with a “China” Sync 3 APIM. Dont know i which vehicle this new APIM was before… Any solutions?

So you bought a US car and I am guessing your in Germany but your profile says US. Than you buy a Chinese APIM that is a J series with 2 USB ports. Odd.

I live in germany but i bought a US Car. I bought this APIM at Aliexpress, dont know i which car was it before.

That is a counterfeit APIM. You can never change anything on it, it was written by eMMC. Return it and buy a proper one not from there.

Thanks for the answer. But what means “Fake APIM”? What was the APIM before the eMMC coding? I mean everything works nice and smooth (GPS, newest maps, newest Sync Software… everything okay).

It will work but you can’t update the firmware, etc.

It seems that the serial number MX5300UR is used by the hackers in that software image. There are tons of these on the web for sale. All with the same MX5300UR serial number.

I never thought that those APIMs exist. My sticker is a little bit different and say “Assembled in C***” China? czech? Nevermind… I´m glad that everything works perfect and it isnt the biggest thing that i cant have a calm screen.

But i wonder: What was these APIMs befor the Chinese hacking? SYNC 3.0???

When you see the dual USB ports on the APIM it is the first Gen Sync 3 module.
