I have an iPhone 4S, the wife has an older Windows Phone 7 (or whatever the name is).
From the very beginning, her phone automatically does voice dictation and prompting of text messages. A text comes in, her car audio notifies her, and asks if she wants to read it, then it reads it over the audio. Finally it asks if she wants to reply, then she can dictate a message and send it...no requirement to activate anything...all seamless.
My iPhone 4S in the same car, will not do anything...(nothing to select in bluetooth settings.)
So it is not necessarily the car, it is the iOS.
I want to know, what implementation is in the Windows Phone that is missing from iOS.
I want to upgrade her to an iPhone, but we will lose that functionality.
