Do we have a mute wire for the stock radio? I am going to have a friend help me install my motorola bluetooth kit Friday, and wonder if my radio can mute with an incoming call like it does with my navigation and onstar.

From what I understand from reading the bluetooth carkit manual I can mute the stereo if I find this wire...

 

That's a good question, I would like to know also.

 

If you can, take some pictures, this is an install I'd be interested in.

 

Anyone? There has got to be a mute wire... since the navi and onstar both mute the stereo-

 

For your '03 the audio mute signal wire is white/black and is connected to terminal 3 in the input and output connector on the navi harness. Terminal 3 is the top row 3rd from the left.

On the back of the navi unit it is connected to cavity A14 of the larger wiring harness. cavity A14 is on the bottom row 4th from the left.

Hope this helps.

 

Thanks Steve, I'll let you know how it works out!

 

Just remember, this wire has to be grounded out.
Thats what it will do to mute it, so your bluetooth kit has to have a ground out when incomming calls.
do not apply power to this wire or it will cause feedback and might blow something.
