Hello, I have an after market Kenwood stereo system that doesn't have 2-way telephone mute. I have a hands free Nokia (CARK-91US) system installed in my car. It has a wire connection for the mute on the radio but my radio doesn't have the mute connector. Is there some way possible to connect this wire to the radio so that I have the mute feature? This feature mutes the car radio automatically during a conversation and then returns to the previous volume gradually after the phone is hung up. Thanks in advance. Please email me direct at bigdaddyc@net-art.de
