My understanding from balders who updated from sync 2 to sync 3 is you use the "as built" data from a sync 3 car.What happens if you swap to Sync 3 as far as updates for the Sync system and maps go? I'm sure my local Ford dealer would have a meltdown trying to figure out Sync 3 updates in a 2016 model. Or is it all done over wifi DIY at home (apart from maps?)
Setting changes using FoCCCus can be done using FORScan which is recommended. FoCCCus hasn't been supported since circa 2015 and will possibly only work up 2016 cars as the configuration files for later models are missing. The BCM changed in the Kuga for 2017 cars.It's not that one I'm afraid. I've already done that it's setting 172 in Focccus someone said you have to change it but didn't post what to change it to.
