How do I get my iphone 4S to output phone calls to my car stereo over USB?
I have a JVC KD-X40 stereo. Music and navigation audio outputs to the stereo but phone calls switch to the internal speakers. I don't see any reason to pay for a bluetooth handsfree system when the iphone speakerphone works great. Any ideas on how to get the phone call to come over the car stereo instead of through the tiny built in speakers of the phone?
Thanks in advance for any suggestions.
iPhone 4S, iOS 6
