I have an iPhone 4 with the latest Google Maps app on it. My phone is paired to my '12 Audio System. When I fire up Google Maps to give me directions, the audio comes through the speaker system automatically which is "great." However, after every direction from Google Maps (e.g In 1/4 mile turn right on...) the hands free calling function announces "Call Ended." After EVERY single direction which is somewhat annoying. Anyone know if there is a way to stop that from happening?
