Cell Phone to HU Mute?

[Biker]

Is there an inexpensive way to have my Bluetooth Motorola RAZR Mute my HU?

My Kenwood Hu does not support the Bluetooth adapter that monitors the phone but it does have a wire to mute the sound. I dont need a fancy Motorola Bluetooth Car kit with Voice recognition etc. All I want is when I recieve a call my HU mutes and I use the phone.

Thanks

near as i can tell you need the blue tooth adapter for it to work. Or you need a car kit for your phone that has a mute wire that tells the deck to mute. I had a Nokia in car system that had the mute for the deck and it worked great.
