When I used iMaps for turn by turn directions in my car, the voice would break in over the radio or even sound through the car speakers when the radio is off. The option for HFP, I think, used to be on the same screen that you would pick the sound source (iPhone or handsfree). Now, I can only hear iMaps if my radio is set to the bluetooth setting. I went from a 5S ios7 to a 6 with iOS8 so I'm not sure if this is an iOS thing or an iPhone version thing. Does anybody know how I can turn HFP back on? Thanks.
