its not about what needs activating in ucds its putting focus mk4 or MY18.5 sync firmware files into the earlier sync and then using tools to repartition the internal memory and certain files are now blacklisted so only early versions of 3.4 work with the tool
Did the F8 map update on mine last Sunday on a run out to the East Coast, The 3.4 upgrade is beyond me I was so proud I did the Map update without a hitch.
Doesnt work Coastliner – says I am up to date. Then again I am running 3.4 which isnt supposed to be for our cars so it wont give me a 3.4 update based upon my VIN number…
