This is a guide for adding an AUX input for the NCDC 2013/15 units, as time has marched on the lasers in these units have really begun to die off. Add to the fact the CD changer (CDC) units easily get stuck, an AUX input is really useful.
In my case, the CDC unit broke some time ago and would not eject. Having used modern cars with bluetooth music streaming, I found it really useful. This guide allows you to add an aux input, to then use with a bluetooth adaptor.
**Note** That my guide here does not make the CDC switchable, this will make it only AUX input and render the CDC useless. You could wire a switch in if you want instead.
Tools needed:
Torx T9 & T7
8mm spanner/socket
Soldering Iron + Solder
Wire strippers
RCA Component Cable
I started off with a standard NCDC 2013 unit:

Use an 8mm socket to remove the bracket at the rear of the H/U.

You need to remove this, which helps grip to the side of the cage. You need a T9 for the larger black screw, do this on both sides of the H/U.

A T7 torx is required to remove the 4 screws holding the CDC to the front of the H/U. Remove these (2x each side)

This will allow the CDC unit to lift up, giving access to the ribbon from the main radio to the CDC, this will just pull down and off. (red plug)

The CDC is now free...

Remove the 2x T7 Torx on the back of the CDC, to allow the top plate to come off, this allows more room to feed cables through later.

Here is my standard RCA cable:
![](http://i264.photobucket.com/albums/ii177/tunnie_84/omega_stuff/NCDC%20Guide/IMG-7975.jpg)
I stripped off the video (yellow) cable, cut off the L/R and stripped them. I had around 0.5m of cable, incase I messed up the connections, to give me spare cable to cut and start again.

Next you need to splice into the ribbon, you need a sharp stanley knife for this. You need to expose (going fromt the left) 1,4,8
1 = Audio L
4 = Audio R
8 = Earth

![](http://i264.photobucket.com/albums/ii177/tunnie_84/omega_stuff/NCDC%20Guide/IMG-7980.jpg)
I then attached 1,4 to L & R audio feeds. You can see here the shielding of the cable, which acts as the earth. I twisted these together to give one connection point. (It's a long time since I did any soldering)

Next up is the earth, for this my method was to use the bracket I took off earlier, I slid this underneath to protect the main ribbon. I then used the soldering iron to burn through the plastic, to expose the core wire, so I could attach the earth.

Everything attached

I then tapped it all up, as I don't have any heat shrink, take note to also tape off un used ribbon connectors. I then put this togther, feeind the cables through into the CDC unit and out the front flap of the H/U.
It's then a case of putting it all back together, you then have assembled unit with RCA ouputs.

You can then use this how you wish, for my needs I bought a £10 cordless bluetooth adpator. So that I could pair my phone to it, for bluetooth audio via Spotify. Press the CDC button to swtich to this audio feed and press play on your device.
