hi all, just bought a car kit for my mobile phone nice & cheap, but one instruction baffles me - "connect the yellow music mute cable to the car stereo".
i know what this does, but which wire does it connect to? and how does it work?
anyones thoughts on this would be a great help.

It's the mute wire which tells your stereo to attenuate. If you have an aftermarket headunit then it should have a mute wire (usually pink).

If you are using the factory stereo then connect the yellow phone kit wire to a relay (you'll need to also fit this) that controls the factory radio's accessories power wire. That way when the phone rings, the phone kit willl trigger the yellow wire and the relay will cut the accessories power to the deck.

I'll make a couple of assumptions here and assume that
1: you have a BA ute
2: you have the factory audio system
3: you are using the mobile phone interface under the dash

Its been a while since i've paid attention to the wire colours so I can't help you there, but on the 4 pin mobile connector under the dash you will find

1: Battery +ve
2: GND
3: ACC +ve
4: Audio mute

Work out the first three and you've found the mute wire (pale green from memory, but don't quote me....)

I installed mine this weekend. There are three sockets hanging behind the fuse box on the drivers side. Two are white, and one is blue. You are going to use the two-pin white, and the four-pin blue.

The two-pin white is an input for the head unit that takes the speaker output from your handsfree kit, and relays it out of the audio system speakers, with you able to control the volume.

The blue four-pin provides 12v, 12v acc, Gnd and Mute.

The pin config is as follows:
___
_| |_
|A|B|
|C|D|

Looking into the blue socket (With the factory cables coming out of the back, away from you), A = 12v, B = GND, C = 12v Acc, D = Mute.

I have connected my handsfree to the head unit input via the 2pin plug at the rear of the fuse box..I have a weid noise coming out of the speakers whilst on the phone, it sounds a bit like a heartbeat!!

There are a few things that affect handsfree kit interference:

1. Ensure that your Mic cable goes nowhere near the antenna cable
2. Ensure that the antenna cable goes nowhere near the head unit
3. Don't mount the handsfree box near the head unit
4. Ensure that the handsfree speaker cables going into the plug behind the fusebox are correct polarity.
