I'm about to install a H/F bluetooth kit and would like to have it mute the audio from the radio.
The radio is the stock Mercury "Premium" sound system with the cd changer in the trunk and a CD/Cassette player in the dash. The unit does have a button on the head unit for mute/phone.
If it matters the Bluetooth unit is a Motorola IHF1000
Thanks!

If you can not find out anything else, Audiovox has the following info for the amp turn on wire.  It will probably require a transistor and a relay to interrupt the amp turn on wire during a call.  If you want to go this route, I can post a diagram for you.

Hi,

I believe it is Pin 7 at the main connector of the radio..same row as the Battery and Accessory wires.  If the Battery wire is Pin 1, Accessory Pin 2...well you get the idea.  And it is active low (negative/ ground signal).

Thank you much, it was pin #7, when I connected it to ground the radio display said "Phone"
Of course there was no wire in the harness to connect to but I was able to jury rig something that I believe will work fine, worst it'll do is not mute the radio.
I'm guessing that this radio was designed to interface with a phone kit of some sort, of course there is nothing in the Ford shop manuals about the connections for the radio other than the power and speaker connections.

i've done searching online and with contacts I have.  I have found diagrams pertaining to the pinouts at the back of the radio and descriptions/functions.  When the mute input is activated, it enables a mono line input.  This in turn outputs sound on the front speakers...if memory serves me correctly.  The radio will need to be on for this to be possible of course. 

As for a terminal to insert into the factory connector housing, there are a few options.  The connectors are made by Molex, HDAC 0.64 series...The Molex website has references to Ford, Tyco and Molex part numbers.  Metra has their 71-5520-1 connector set.  Remove a terminal for your use, I believe Metra fills all possible positions with a terminal and wire.  A phone interface harness will provide the same options as above...usually they are 'T' style harnesses.

I have a 2003 Explorer and like you, am looking for the pin/wire that I can connect my Sony HCB-700 radio mute wire to so the radio will mute when a call comes in. Any ideas/advice?
