So I have a AUX and iPod connector in my car, but no mic. I want to be able to hook up my iPhone to the car stereo as a handsfree calling system. What I have tried in the past is hooking up a mic between the phone and the aux connector. It worked, but not very well. I always got people complaining about there being too much echo that it was unbearable. I guess the MIC i added inbetween was a cheap single mic which picked up the sound coming from the car speakers. Anyone tried anything similar that actually worked well?? I'm open to trying creative things. Thanks in advance for all the creative input!
