Hi. Ford are creating an update to allow the Sync 2 head unit system to display 128 characters, due out end of April. This problem is also on Sync 3 head unit systems.
It seems 2017 Ford Focus with MK3 system in the UK can accept and display 128 characters and also we are aware of a 2017 Kuga in Italy that displays text correctly but no 2017 Kuga in the UK displays text correctly, along with Kugas with Sync 2 systems.
Ford say its the head unit that is causing the problem, but Sony would know the correct text length. It also seems that playing a CD on Sync 3 does not display full album/track text, but playing same track ripped to a memory stick, displays text OK. I have not checked if Sync 2 has this problem
I have spoken with someone at Ford Germany last February and they confirm there is a problem and they are working on a fix for release end of April. I think it will be a dealer update.
