Has anyone updated their iPhone to iOS7.1?
Theres a feature there that I have been looking for, for a long time in my A3... its something called HFP (Hands Free Profile).
What is HFP you ask? It allows the phone to dicatate the directions through the A3 even when the phone is connected just as a handsfree device (not audio player).
So theoretically you could be playing the radio or listening to music via the SD card and then if you have your iPhone navigating you somewhere (only with Apple Maps though) it will dictate the directions through the AMI system going back and forth between music and the voiceover.
The reason I ask is because I've always had issues upgrading to newer versions, so I would rather verify the function works on the A3 before I upgrade the fw.
