Gerry no mate, the keys have to be turned but not fully, ie engine should not be turning. Just follow the instructions in that pdf to the letter and you'll be good!
I would like to report that I did the update via USB stick this morning and have been testing the bluetooth phone ability throughout the day. I made and received 24 calls in total , and I am very happy to report that they all worked perfectly!
This made me happy like a little boy during Christmas 🙂 I was very disapointed when my 2009 Ford Mondeo Sony unit started playing up big time after I updated my iPhone 4 to iOS 5. I am on the road most of the day and really need to be able to make / receive calls while Im driving. I also absolutely loved the great Ford Sony system since the call quality and volume was the best that I have found in many different cars.
I struggled for about a week and then my radio unit locked solid, even when you turn off the engine and lock the car the radio unit would still stay on , locked in its own world thinking it is still busy on a call with an unknown number... This was bad because this would go all throughout the night and I am sure this could deplete the battery. (Although it didnt even with the GPS being on charge the whole night at the same time as well!)
Ended up having to have the fuse pulled out (apparently disconnecting battery wouldve been ok as well)
When I saw the post from Shamu35 (my hero!) I was a bit sceptical that it could be such an easy fix after all the struggles with Apple and the Ford Dealership. But it worked and for all of you with the problem and the massas that will still go through the same motions, just do the USB update!
It begs an interesting question still : Who's fault is it ? Apple launches new OS and suddenly the Ford system doesnt work anymore - so its Apples fault. BUT then Ford has a "fix" which you have to download and install on your system and then it works fine again - so that means Ford had to fix / upgrade their system... hhmmm difficult one.
Nevertheless I do believe communication from both companies was shocking. Apple should have responded to all their loyal followers when they realised they have a problem. At the same time it would not have been difficult for Ford to issue a memo to all its branches to inform the people about the issue and point them in the right direction. From what I have red from other peoples experiences with Ford dealerships was the same as mine - they were clueless and in my case the guy told me if Ford releases an update it would not be covered under my warranty and I would have to pay the $300 !?!?! to do the upgrade. I almost told him he can go shove it deep where the sun dont shine, but then thank fully Shamu posted that link and life returned back to normal.
Take care people! I love both my iPhone and my Ford again!
