The local wifi on the APIM is only used as a backup to the TCU in a Sync 4 setup. If you were to set up an APIM, TCU, and GWM with the private networking (ETH) along with HS4 you might get it to work that way. It will not work on it’s own as far as I have seen.
And more than likely change the VIN in the BCM to the Donor VIN to spoof it to the Ford computers. Than change it back once you have the update. I have done this successfully with SYNC 3.
To jump in on this, I believe I mentioned it before but every update on a module from the new FNV platform (so SYNC 4) is VIN specific and the installation manifest is encrypted and signed by Ford for that VIN. So even if you install a module and somehow get an update package you will not be able to update it. Spoofing the VIN will also not work for OTAs as Ford’s backend servers do a whole vehicle network check prior to issuing updates. If any software/module is missing from the vehicle or is not in the expected configuration, there will be no OTA provided.
TLDR - updates will never work on retrofitted modules unless someone can crack the installation manifest and get past a digital signature check.
I only spoof the VIN with the downloaded updates on Sync 3 and it’s really only necessary for Map updates.
Yes, it’ll work for sync 3.
Guys, I want to test sync 4 on the bench. Can anyone share a wiring diagram how to connect it with GWM 2019? Or there’s anything else needed? Thanks
2019 GWM is probably a J or K series. It will not work with Sync 4.
What does not work so far? Nice job man
only the air conditioning is not working. I heard that you need to change the wiring or the module.
I got Sync 4 install on my ford fusion 2016 wanted to do sync 2 to sync 4 retrofit got everything to work but 2 issues my backup camera lines do not show and Navigation is inaccurate can anyone post their APIM sync 4 with ford fusion configuration not sure if my configuration if correct on line 7D0-05-01 to 7D0-07-04 is on point since I’m using sync 2 profile to go on by the way if anyone is trying to do the same as me I removed pins 53/54 just to get the module to boot up with my car issues fixed and pins 16/17 off the APIM module to fix my radio and AC system and my doors controls I removed it directly off the APIM module in case I want to revert back to my original APIM without a wire harness add on and disconnected the gyro inside the dash as the compass was going nuts.
Why?, just use SYNC 3, what benefit does SYNC 4 has especially in a car from 2016
Sync 3 APIM was more expensive than a Sync 4 APIM the price was what made me buy it in all for sync 3 was going to be around $300 - $500+ I would need the gps and usb and sync 4 cost me $60 just saw the price and made my decision easy I can easily throw $60 for a gamble testing with that price I don’t see any difference other the. Wireless CarPlay and that the price $60 with usb adapter and gps antenna $110 if it didn’t work I would just be out of $60 and I can reused the usb adapter and antenna and get sync 3
you have a configuration, how did you make the air conditioning work for you? where did you get the maps for sync4?
Thanks can’t wait to compare with my Apim configuration for the maps when I bought the Apim it already came with navigation on the back of the Apim said 32gb I’m in USA it already had the maps installed so I lucked out for my AC I removed pin 16/17 since for some reason it was shorting my radio my doors control and AC controls can’t really test navigation on it yet since it’s supper not accurate atm but it does start to navigate when I input a location I’ll post pictures later if I can get navigation to accurately work.
in sync3 the gps antenna is connected to it and in sync4 the gps antenna is connected to the tcu. you need to change the configuration. I have a file if you want with a description.
Yes plz send me that configuration file just want to cross all my options just in case I missed something.
After Sync3 to sync4 APIM swap now Forscan can not detect the TCU module. What could it be?
Maverick 2022 Lariat AWD FX4 Lux.
(pins 53 & 54 removed)
I never figured this out, another reason why I went back to sync 3
