I've been trying to update my SYNC system using the automatic updates feature over wifi for a long time now. When my car connects to wifi, it shows that it has begun updating but I've never seen it finish. Each time it connects to wifi, it starts downloading the same file from the beginning! I looked into doing a manual update by USB but I can not download the file from the Ford owners site because according to my VIN, the car is all up to date? WTF. If its all up to date then why would it keep trying to download files over wifi? Any ideas?
