Hi all,
I have a 2016 Ford Flex sel that originally came with an older SYNC system. I retrofitted a newer SYNC 3 APIM into it “old one died”
On the screen, About SYNC shows:
SYNC 3, Software Version: 3.0
Build: 19205_PRODUCT
VIN: 2FMHK6C87GBA08280
Gracenote: 1.1.1.1139 (NA‑0010)
Navigation Maps Version: NA 1 14
I installed Syn3 Updater on my Windows PC and set:
Current version: 3.0.x, Region: NA, Navigation: Yes
New version: 3.4.23188 (NA maps)
When I try to proceed, I get the red error saying:
You have specified that you have a MY20 (Manufacture Year 2020+) SYNC 3 unit
You can not do the following:
– Upgrade from 3.0 or below to 3.2 or above if applicable
– Install ESN locked map releases
– Change region
My situation:
Car is a 2016 Flex sel, but the APIM is newer than the car (likely a MY20‑style unit).
I do not want to brick this APIM.
I’d like to get to SYNC 3.4 with North America maps if it’s safe for this hardware.
Questions:
With this MY20 APIM in a 2016 Flex, is there a safe path using Syn3 Updater to go from 3.0.19205 → 3.4.x?
If yes, what exact settings should I use (install mode, version, map package, and whether to keep MY20 protection enabled)?
If no, is my only safe option to have a dealer or FDRS update this APIM instead?
I’ve attached a screenshot of the MY20 error and can also provide the APIM part number if needed.
Thanks in advance for any guidance
