It seems i'd get a more funcitonal experience if I used my iPhone 4S via the USB connection instead of purely via Bluetooth. By this I mean you get feedback on the LCD display and the voice-commands you can use are greatly increased compared to using BT.
When I use BT I have no problems at all but when I plug my iphone into the USB socket and press the aux button to change to USB I can't get it to work. I've tried to play music but neither the controls on my phone or the controls on the car work. Sometimes it doesn't play at all, other times I can see the track counter moving up and the seek bar moving on my phone but I don't get any sound coming out the car speakers, other times the sound comes from the iphone speaker.
I've played about moving the output of the phone between dock and sync and only sync seems to work.
The whole USB\iPhone side of things seems a bit flaky. What's everyone ele's experience of this?
Also do Ford release updates for the Sync system? Do we get notified of updates or is there somewhere I can go to see what the latest version is and download an update?
