Note: This guide should work with any handsfree car kit that uses an external speaker or that has an auxiliary audio output (I used the Nokia Bluetooth CK-7W Handsfree Bluetooth car kit). A wiring diagram for the head unit connector / wiring loom is linked to at the bottom of this page.
It is really easy to install a car kit that will:
- Play / output sound through the car speakers
- automatically mute the head unit / stereo
..and you don’t need a £40 wiring adapter from autoleads either!
However: your head unit must have a ‘Phone’ button.
You will need:
- A car (Mondeo, Focus, Fiesta…) with a 6000CD head unit that has a ‘Phone’ button.
- A car kit (Bluetooth or wired) – one with an external speaker or an audio out will do
- The 4 head unit removal keys (from ebay).
- Screw driver (Philips).
- Knife / wire trimmers.
- Something to splice wires together.
- Electrical tape (and maybe some glue).
- This wiring diagram
Remove the headunit:
Using 4 keys bought from eBay. There are 4 slots for the keys, which are (roughly) in each corner of the head unit, and are horizontal. They keys only go in one way – with the flat sides of the handle on the outside, facing away from each other. Insert the keys firmly, they should click and then gently pull out together – one corner of mine took a bit of jiggling with the key but when all corners are free, the head unit should come out very easily; if you are pulling a lot then you may not have released one of the corners properly.
Here is a video that shows you how to remove the headunit
Connect the wires:
Unplug the aerial, then the main connector block – this has a retaining arm that needs to be released using the catch at the bottom of the block, then raised 45 degrees; Only then can you remove the block.
You may want to undo some of the tape that secures the wiring together behind the connector – we’ll tidy this up before it all goes back.
Release the bottom left, black rectangular connector from the main connecting block (block B – see diagram, below) that is horizontally aligned with the white block (not the two blocks above this). You may need a small screwdriver to insert into the side of the main block to do this.
Looking at the back of the connector you released, the left side (this is the side with the plastic retaining edge projecting out the side) is where you will insert the bare ended cables for the speaker (pins 1,7). Cut the speaker cable from the car kit and trim to get access to the black and red wire. There is no good way of getting these cables to stay put, I made sure they were inserted properly and then use electrical tape to secure them to the other wires in this plug – so far it has done the trick, if yours come loose, superglue may do the job :). It does not matter which way you insert the black and the red wires; speakers work on alternating current, so there is no positive or negative in that sense.
The top, right hand pin (pin 6) in this same connecting block should be taken (it was on mine), so pick the next vacant pin (pin 5 counting from the left (you insert a speaker cable in to pin 1 and 7)), into this one you will insert the yellow mute cable from the car kit. Again, no good way to secure the pins, so electrical tape should hold it in. In the end I used a bit of superglue to get the cables to stay-put!
There is a nut at the back of the head unit compartment which holds the earth for the stereo – you can undo this a small amount and then insert the black earth wire for the headunit behind it, then tighten it, ensuring the wire does not become loose and is held tight.
The power wires for the hands free kit are the last two pins (15, 16) in the top right block (Block A). Splice the blue wire into one and then the red wire into the other. Now, the car kit will either turn off straight away when the ignition is turned off, or will stay on until it is disconnected from the phone. Test to see which you have and then if you need to, swap the wires leading to the fuse blocks of the car kit to reverse the situation. I have it left on, but its personal preference.
Now reconnect everything, be careful with the wires for the speakers / mute cable they can become loose at this point. Connect the hands free kit wires to the hands free kit.
Test
At this point you can turn on the ignition and test the car kit – if it doesn’t work, check the power light on the hands free kit button is on, if it is you should be able to pair it with a phone. If it is on and there is no sound, check the cables in pins 1, 5 & 7. If no power then check all connections. Make a call to make sure everything works.
Fit the mic / button
Now disconnect the wires for the button and mic, the mic can attach to the roof by the light in the headlining, run the wire behind the lining, where it meets the windscreen, to the A-piller and hide it behind it (remove the door seal). You may need to undo the 5 screws that attach the bottom part of the dash on the drivers side to enable you to get the wire behind it and back out the headunit opening. Once you have this and the button fitted, you can tuck the wiring and then car kit unit into the vacant space below where the head unit slots into.
Now refit head unit and check everything works.
