I have just uploaded the maps (a massive 25GB) and SYNC. Then the car did it's own sync update in the night over the top of that.
Now there are major problems:
Twice the navigation screen has gone jet black with the top line showing as it should. Had to stop and restart the car.
The car keeps dropping Bluetooth to my Samsung, which it used to do, then they fixed it. Now it drops connection again every few minutes.
Pretty poor for such a large company. Very unimpressed and my experience with the customer support and garages is they don't care once you have the vehicle. I have had 3 Fords now, and this might be the last. I don't understand why they cannot engineer a system that works. That is just bad management and QA. I am so fed up with this lack of support.
