I saw an older threads regarding this issue, but I wonder if anyone has found a workaround for the iPhone 4 failing to connect automatically to the Ford Sync system when the car is turned on. My 3G and 3GS never had any issues and would often override the USB input for audio when I started the car due to the auto pairing, but the iPhone 4 has to be paired manually every time I turn the car on. Both are fully updated.....any info out there regarding a possible fix?
