iPhone 4s with Parrot device
I have a parrot car kit and I have my new iPhone 4 s paired no problem. I can call someone and chat, again, no problem, that is until someone else call me while I am talking to another person, I can accept the incoming call but then the iPhone goes back to using the speaker on the handset? yet on my old Nokia I am still connected, any idea's why this happens or how I can remedy my problem?
