bluetooth car kit and audio mute

Hi, I got a bluetooth car kit. I will like to install it to my 2001 Honda accord EX sedan with 6 speakers. One thing I was wondering if my head unit has mute feature. Because when the phone call coming, the mute cable will send a signal to the head unit and mute the audio. Could you let me know if my Head unit has mute function and where can I find it? Also, where can I find information about which cable diagram for my head unit as well? Thank you all in advance. Ultramini

If its factory...no. You will have to wire in a relay to cut the ignition wire on the radio.

Hi Thank you for your reply. So you mean that not all the factory head unit has telephone mute feature? What about the after market head unit? Thank you for your help.
