When using Sync 2 in my MK5 Mondeo found screen difficult to use. For example when adjusting which music files to play I found I was having to touch top of button below item I was selecting. A quick google found a link to following vid: https://youtu.be/jGsoEns1bcQ
Using diagnostic mode shown in vid it was easy to re-align screen, buttons now work where I touch screen and not above.
Diagnostics may help owners with other problems.
