Hi community. I’ve bought above Fiesta for my daughter. The Syncversion is 3.0 Build 23219_PRODUCT
I prepared an interrogator stick and found the model-no: JK2T-14G371-FCC
Is it possible to update it to latest v3.4?
As long as it is not a 2020+ APIM you are fine. Based on that model number and the database here than you should be good. Personally I perfer to look at the sticker just to be safe.
Keep in mind that for your vehicle the only difference between 3.0.23219 & 3.4.232188 is a prettier interface, the two builds were released just slightly over a month apart.
Any thing additional that you might want to try to turn on the 3.4.x gives you requires updating the APIM firmware/calibration as well.
