When I am listening to music over headphone jack in car through AUX cable and I get a phone call, it defaults to the handset for the phone call. I want it to default to the headset jack so I can have a speakerphone call. How can I do this? Also, when listening to music the same way, and I decide to make a voice dial call, it defaults to the handset, not the headset. How can I change this default?
I got a bluetooth speakerphone/radio transmitter from Motorola and problem solved. I think that the problem was that the FM transmitter that plugs in through the headphone jack is only a stereo connector, not the three way stereo and microphone connector, so although the media player assumes is has a headphone connected for playback, the phone app does not detect a microphone so it doesn't default to the headset. I am not totally upset with that logic, just disappointed that it wasn't a default that I could set myself. The bluetooth solved it, though!
