Hi kids. Okay so I just bought a new car stereo with a front aux port for an MP3 player. I've been using my phone plugged into this for my music in the car, and I had the idea of using the same principle as a hands free phone thingy. The theory is that the speech would come through the car speakers, from the headphone port on my phone. The same way the hands free cable works. The only issue is, is the phones mic disabled when the cable is plugged in, as the phoen thinks a hands free headset is attached, and not a cable to the car stereo. Is there a way of having this aux cable attached through the headphone port, but still leaving the mic active? Does that make sense? If so, can someone explain it to me LOL. Thanks Andy.
