I am able to connect my Fascinate to the Aux input of my car stereo but when I make a call with the cable still connected, the internal microphone doesn't work. I have to disconnect the stereo cable and put the phone on speaker. Ideally, I want to be able to keep the stereo cable connected and hear the person over the radio, and be able to talk. Is there a stereo cable with a microphone built into it that can be used for this purpose? I had one for my HTC device (Amazon.com: Handsfree Stereo Headset Headphones + Microphone + 3.5mm Adapter Converter + Car Home Charger Plug Port For All HTC Phone Smartphone PDA: Cell Phones & Service) that worked very well, but it would only push mono to the stereo. My car doesn't have bluetooth so I can't go that route. What's my best option here so I can play music in my car and make handsfree calls without bluetooth?
