The pioneer 4100nex works great in my Mazda 6 except for the phone calls. I hear them perfectly but the other person hears their own echo and its very frustrating to have a conversation when they don't want to talk. I tried placing the microphone everywhere in the car, changing out the microphone with another, turning down the mic sensitivity, turning down the Bluetooth volume before syncing the phone and using another phone. PLEASE if anyone have any other input, I would appreciate it. Thank you.
