This is non sense and as I have mentioned in original Sync was not like that.
I am gonna to explain you step by step why:
When you drive slowly next to an obstacle and distance doesn't change but you are around 5 inches to an obstacle you have keep on your screen if distance on the monitor is changing or not to avoid hitting, but when animation disappears after 5 sec you can not control when you are very close to an object. If it's still not clear I can record a video for explanation.
On navigation Sync animation was still on, untill switch was on.
